According to the equation, a person who weighs 63 kg is predicted to be approximately 141 centimeters tall.

The equation given is Y = 0.91X - 65.5, where X represents the height in centimeters and Y represents the weight in kilograms. To predict the height of a person who weighs 63 kg, we need to solve for X, the height in centimeters.

To do this, we can plug in the given weight of 63 kg for Y in the equation and then solve for X. So, we have:

63 = 0.91X - 65.5

Adding 65.5 to both sides, we get:

63 + 65.5 = 0.91X

Simplifying, we have:

128.5 = 0.91X

Finally, to solve for X, we divide both sides by 0.91, giving:

X = 141.21

An equation in slope-intercept form for the perpendicular bisector of the segment with endpoints H (-3, 2) and K (7, -5) is y = -0.7x - 0.1.

In Mathematics and Geometry, the point-slope form of a straight line can be calculated by using the following mathematical equation (formula):

y - y₁ = m(x - x₁)

Where:

First of all, we would determine the slope of this line;

Slope (m) = (y₂ - y₁)/(x₂ - x₁)

Slope (m) = (-5 - 2)/(7 + 3)

Slope (m) = -7/10

Slope (m) = -0.7.

At data point (-3, 2) and a slope of -7/10, a linear equation in slope-intercept form for this line can be calculated by using the point-slope form as follows:

y - y₁ = m(x - x₁)

y - 2 = -7/10(x + 3)

y - 2 = -7x/10 - 21/10

y = -7x/10 - 21/10 + 2

y = -0.7x - 0.1

The probability of a score for a recent basketball game, shenille attempted only three-point shots and two-point shots is 18 points in the game. The answer is Option B.

Let x be the number of three-point shots and y be the number of two-point shots attempted by Shenille.

Then, we have:

x + y = 30 (total number of shots attempted)

Let's solve for one of the variables. For example, we can solve for x by subtracting y from both sides of the equation:

x = 30 - y

Now, we can express Shenille's points in terms of x and y:

Points = 3x + 2y

Substituting x = 30 - y, we get:

Points = 3(30 - y) + 2y

Points = 90 - y

Shenille's success rate for three-point shots is 20%, so the number of successful three-point shots she made is 0.2x. Similarly, the number of successful two-point shots she made is 0.3y.

Total points scored = (0.2x)(3) + (0.3y)(2)

Substituting x = 30 - y, we get:

Total points scored = (0.2(30 - y))(3) + (0.3y)(2

Total points scored = 18 + 0.4y

Now we need to maximize the total points scored by Shenille. Since she attempted 30 shots in total, we have:

y = 30 - x

Substituting this into the equation for total points, we get:

Total points scored = 18 + 0.4(30 - x)

Total points scored = 30 - 0.4x

This is a linear function, which is maximized at its endpoint. The maximum value of this function occurs at x = 0, which means Shenille attempted all two-point shots. In this case, y = 30, and the total points scored would be:

Total points scored = 0 + 0.3(30)(2)

Total points scored = 18

There are 173 kinda-prime positive integer less than 1000.

To find the number of kinda-prime positive integer less than 1000, we'll follow these steps:

1. Understand the definition of a kinda-prime number: A positive integer is kinda-prime if it has a prime number of positive integer divisors.
2. Determine the number of prime numbers less than 1000: There are 168 prime numbers less than 1000, as given.
3. Determine the possible prime number of divisors: Since 168 is not too large, we only need to consider 2 and 3 as possible prime numbers of divisors for a kinda-prime number.
4. Analyze the cases:

Case 1: Kinda-prime numbers with 2 divisors (prime numbers)
All prime numbers have exactly 2 divisors (1 and itself). Thus, all 168 prime numbers less than 1000 are kinda-prime.

Case 2: Kinda-prime numbers with 3 divisors
Let N be a kinda-prime number with 3 divisors. Then, N = p^2 for some prime number p. To find the suitable prime numbers p, we need[tex]p^2 < 1000[/tex]. The prime numbers that meet this condition are 2, 3, 5, 7, and 11 (since 13^2 = 169 > 1000). Therefore, there are 5 additional kinda-prime numbers ([tex]2^2, 3^2, 5^2, 7^2, and 11^2[/tex]).

With 90% confidence, we can estimate that the true population mean lies between 13.96 and 16.04.

If the population appears to be normally distributed, and σ (population standard deviation) is unknown, we can use a t-distribution to calculate the confidence interval.

To find the confidence interval, we need to use the following formula

CI = X' ± t_(α/2, n-1) × (s/√n)

Where X' is the sample mean, t_(α/2, n-1) is the critical t-value based on the desired confidence level (α) and the sample size (n-1), s is the sample standard deviation, and √n is the square root of the sample size.

Given that we have a confidence level of 90%, α = 0.10, and we need to find the critical t-value for a two-tailed test with 10-1=9 degrees of freedom. Using a t-distribution table, we find that the critical t-value is approximately 1.833.

Assuming that we have a sample mean of X' = 15 and a sample standard deviation of s = 2, we can now calculate the confidence interval

CI = 15 ± 1.833 × (2/√10)

CI = 15 ± 1.04

CI = (13.96, 16.04)

To find the argument of the complex number z = 1/16 - (sqrt(3)/16)i, we need to find the angle that the complex number forms with the positive real axis in the complex plane.

We can start by finding the magnitude of z, which is the distance between the origin and the point representing z in the complex plane:

|z| = sqrt( (1/16)^2 + (sqrt(3)/16)^2 )

= sqrt(1/256 + 3/256)

= sqrt(4/256)

= 1/4

Next, we can find the argument of z using the formula:

arg(z) = tan^(-1)(Im(z)/Re(z))

where Im(z) is the imaginary part of z, and Re(z) is the real part of z.

In this case, we have:

Re(z) = 1/16

Im(z) = -(sqrt(3)/16)

Therefore, we get:

arg(z) = tan^(-1)(Im(z)/Re(z))

= tan^(-1)(-(sqrt(3)/16)/(1/16))

= tan^(-1)(-sqrt(3))

= -60° (in degrees)

So, the argument of z is -60 degrees (or -π/3 radians).

Step-by-step explanation:

The height of the pistol after 10 seconds is 783 feet.

We can use the method of finite differences to find the degree of the polynomial function that models the data. The first differences are:

3, 18, 37, 56, 72

The second differences are:

15, 19, 19, 16

Since the second differences are constant, we know that the function that models the data is a quadratic function of the form:

h(t) = at² + bt + c

where a, b, and c are constants to be determined.

To find a, we can use the fact that the coefficient of t² in the quadratic function is equal to half of the second difference. Thus, we have:

a = 1/2(15) = 7.5

To find b, we can use the fact that the coefficient of t in the quadratic function is equal to the first difference minus twice the coefficient of t². Thus, we have:

b = 18 - 2(7.5) = 3

To find c, we can use the fact that the constant term in the quadratic function is equal to the value of h(0). Thus, we have:

c = h(0) = 3

Therefore, the equation that models the data is:

h(t) = 7.5t² + 3t + 3

To find the height of the pistol after 10 seconds, we can substitute t = 10 into the equation:

h(10) = 7.5(10)² + 3(10) + 3

h(10) = 750 + 30 + 3

h(10) = 783

Thus, the height of the pistol after 10 seconds is 783 feet.

Step-by-step explanation:

If the expressions given, only C) if( x == 1) is always true.

In the given code fragment, the value of x is read from the user using the scanf() function. The value of x can be any integer value, depending on what the user enters. After the value of x is read, the program checks the value of x using a conditional statement (if statement) and executes the code inside the if statement only if the condition is true.

Expression A) if( x = 1) assigns the value 1 to x and then checks if x is true. This means that the condition is always true, because the assignment operation (=) returns the assigned value (in this case, 1), which is a non-zero value and therefore considered true in C programming.

Expression B) if( x < 3) checks if x is less than 3. This expression is not always true, as x can be any value greater than or equal to 3, in which case the condition would be false.

Expression C) if( x == 1) checks if x is equal to 1. This expression is always true if the user enters the value 1 for x.

Expression D) if((x/3) > 1) checks if the integer division of x by 3 is greater than 1. This expression is not always true, as x can be any value less than or equal to 3, in which case the result of the integer division by 3 would be 1 or less, in which case the condition would be false.

James started with 78 rocks, as he gave away 46 rocks and had 32 rocks left.

The problem states that James gave away 13 rocks to Bill, 18 rocks to Lill, and 15 rocks to Mark. Therefore, the total number of rocks he gave away is the sum of these three amounts

13 + 18 + 15 = 46

This means that James had 46 fewer rocks after giving them away. The problem also states that he had 32 rocks left after giving some away. We can use this information to figure out how many rocks he started with by adding the number of rocks he had left to the number he gave away

46 + 32 = 78

By Pythagorean , Eli's home is thus roughly **11.4 miles** from Salem when viewed from a straight line.

A fundamental relationship between a right triangle's three sides in Euclidean geometry is known as the Pythagorean theorem. The hypotenuse is the side that forms the right angle, and the rule says that the square of its length is equal to the sum of the squares of the lengths of the other two sides. In other words, if the hypotenuse is length c and the legs of a right triangle are lengths a and b, then a²+ b² = c² .

Call Yardley Y, Salem S, and Eli's home E. As far as we are aware, Y is located 7 miles from E and 9 miles from S.

We can check that the distance between Eli's house and Salem is the hypotenuse of a right triangle with Yardley as one of the vertices because Eli's house is located due west of Yardley and due south of Salem. The Pythagorean theorem can be used to determine this distance.

Eli's home is 11.4 miles from Salem at a distance of√(7 + 9 ) = √(130).

√(130) = 11.4miles

Eli's home is thus roughly **11.4 miles** from Salem when viewed from a straight line.

Answer:

the correct dosage of the medicine for a 145 lb. woman would be approximately 3.22 cc

Step-by-step explanation:

To calculate the correct dosage of the medicine for a 145 lb. woman, we can use the following formula:

dosage = (weight of patient / weight of reference patient) x reference dosage

where the weight of the reference patient is 180 lb. and the reference dosage is 4 cc.

Plugging in the given values, we get:

dosage = (145 / 180) x 4

      = 3.22 cc (rounded to two decimal places)

Therefore, the correct dosage of the medicine for a 145 lb. woman would be approximately 3.22 cc. However, it's important to note that dosages of medications should only be determined by a qualified medical professional based on a number of factors, including the patient's weight, medical history, and current condition.

Plugging in the values given into the expression, and simplifying, we would have our answer as: B.  [tex]\frac{9}{25}[/tex]

Given that, a = 5 and k = -2, substitute the values into the expression given and simplify:

[tex](\frac{3^2(5^{-2})}{3(5^{-1})} )^{-2}[/tex]

Simplify:

[tex](\frac{9 * \frac{1}{25} }{3* \frac{1}{5} } )^{-2}[/tex]

[tex](\frac{\frac{9}{25} }{\frac{3}{5} } )^{-2}\\\\(\frac{9}{25} * \frac{5}{3} } )^{-2}\\\\(\frac{3}{5} )^{-2}\\\\ = \frac{9}{25}[/tex]

The exact volume of each cone-shaped basket is (240/π) cubic inches.

The formula for the volume of a cone is,

V = (1/3)πr^2h

Where,

V is the volume of the cone

π is the mathematical constant pi (approximately 3.14159)

r is the radius of the base of the cone

h is the height of the cone

In this case, the height of the cone-shaped basket is 20 inches and the radius is 6 inches. So, substituting these values into the formula,

V = (1/3)π(6^2)(20)

V = (1/3)π(36)(20)

V = (1/3)π(720)

V = (240/π) cubic inches

Hence, volume is (240/π) cubic inches.
