Answer:
35 two pointers, 18 one pointers
Step-by-step explanation:
equations:
x + y = 53
x + 2y = 88
solving them:
y = 35
x = 18
The grades on a math midterm at Springer are roughly symmetric with \mu = 78μ=78mu, equals, 78 and \sigma = 5.0σ=5.0sigma, equals, 5, point, 0. Omar scored 646464 on the exam. Find the z-score for Omar's exam grade. Round to two decimal places.
Answer:
-2.8
Step-by-step explanation:
Given that:
Mean, μ = 78
Standard deviation, σ = 5
Omar's score, x = 64
The Zscore of Omar's score :
Zscore = (x - μ) ÷ σ
Zscore = (64 - 78) / 5
Zscore = - 14 / 5
Zscore = - 2.8
Hence, Omar's exam score is - 2.8
Answer:
-2.8 is correct
Step-by-step explanation:
What happens when the y-intercept is greater than 1?
What happens when the y-intercept is less than 1?
Answer:What happens when the y-intercept is greater than 1?: more than one y-intercept would violate this, since it would mean that there are two outputs for x=0. Therefore, it is not possible for a function to have more than one y-intercept. This function never crosses the y-axis because, since you can't divide by zero, it is undefined at x=0.
Step-by-step explanation:
9514 1404 393
Answer:
The graph intersects the y-axis above the point (0, 1)The graph intersects the y-axis below the point (0, 1)Step-by-step explanation:
Nothing special happens when the y-intercept is above or below the value of 1. The y-intercept is where the function's graph intersects the y-axis.
When the y-intercept is greater than 1, the graph intersects the y-axis above the point (0, 1).
When the y-intercept is less than 1, the graph intersects the y-axis below the point (0, 1).
__
The meaning of the y-intercept will depend on what the graph is modeling. No information about that is provided here.

An angle measures 32 degrees. Through what fraction of a circle does the angle turn? I need help !!!!!!!!
Answer:
4/45
Step-by-step explanation:
The sum of angles in a triangle is 360 degrees
If the angle measures 32 degrees, the fraction can be represent as 32/360
32/360 has to be converted to its simplest form. To this divide both the numerator and the denominator by 8. This gives 4/45
Consider the polynomial function h(x) = -2x^5+ 8x^4
2x^2+15.
What is the end behavior of the graph of h ?
Answer: B
Step-by-step explanation:
Applying limits, it is found that the end behavior of the graph is:
B. As [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex], and as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex].
The function is:
[tex]h(x) = -2x^5 + 8x^4 - 2x^2 + 15[/tex]
To find the end behavior, we apply the limits as x goes to infinity, in which just the term with the highest exponent is considered, hence:
[tex]\lim_{x \rightarrow -\infty} h(x) = \lim_{x \rightarrow -\infty} -2x^{5} = -2(-\infty)^5 = -2(-\infty) = \infty[/tex]
Then, as [tex]x \rightarrow -\infty, h(x) \rightarrow \infty[/tex]
[tex]\lim_{x \rightarrow \infty} h(x) = \lim_{x \rightarrow \infty} -2x^{5} = -2(\infty)^5 = -2(\infty) = -\infty[/tex]
Then, as [tex]x \rightarrow \infty, h(x) \rightarrow -\infty[/tex]
Hence, option B is correct.

Step-by-step explanation:
if it was -3.3 then it would change to 3.3 but because it is already in the positives it stays a positive plz double chesk if needed tho
Answer:
[tex]3.3[/tex]
Step-by-step explanation:
Absolute value expresses the distance of a number from 0.
For this reason, no matter if the number is negative or positive, the absolute value of it will always be positive.
In this case, it is simply [tex]|3.3|=3.3[/tex].

Answer:
y=mx+b
so
y=8x+3. the second answer choice
Answer:
y=8x+3
Step-by-step explanation:
we are given the slope (m) as 8 and the y intercept (b) as 3.
The given options are in y=mx+b format.
Use your given information to write the equation in y=mx+b form
we know that m (slope) is 8. The equation so far is y=8x+b
we know that b (y intercept) is 3. So the equation of the line is y=8x+3

16x – 12 = 30x – 8 solve
Answer:
-2/7
Step-by-step explanation:
solve for x so -12+ 8 = 30x - 16x so -4 = 14x so x = -4/14, so x = -2/7
Answer:
x=-2/7
Step-by-step explanation:
you have to let x be on one side so you subtract -30x to each side.
16x-30x-12=30x-30x-8
-14x-12=-8
now you gotta add 12 to each sides to delete -12.
-14x-12+12=-8+12
-14x=4
divide -14/14x=14/4
-x=2/7
x=-2/7

What is the domain of the function
Answer:
[tex]x\geq -6[/tex]
Step-by-step explanation:
The domain of a function is all of the values that [tex]x[/tex] can be under that specific function. In this case, we're asking what values of [tex]x[/tex] allow [tex]\sqrt{\frac{1}{3} x+2}[/tex] to exist.
In order for square roots to exist, the quantity under the square root must be greater than or equal to [tex]0[/tex], because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for [tex]x[/tex]:
[tex]\frac{1}{3}x+2\geq 0[/tex]
Solving this inequality, we get:
[tex]\frac{1}{3}x+2\geq 0[/tex]
[tex]\frac{1}{3}x\geq -2[/tex] (Subtract [tex]2[/tex] from both sides of the inequality to isolate [tex]x[/tex])
[tex]x\geq -6[/tex] (Multiply both sides of the inequality by [tex]3[/tex] to get rid of [tex]x[/tex]'s coefficient)

The combined area of a square and a rectangle is 33 square meters. The width of the rectangle is 1 meter more than the length of one side of the square and the length of the rectangle is 3 meters more
than its width.
a) Calculate the dimensions of the rectangle and its perimeter
b) Calculate the dimensions of the square.
Answer:
4 m = width of the rectangle.
6 m = length of the rectangle
20 m = perimeter of rectangle
3 m = side of the square
Step-by-step explanation:
Let s = length of side of square
s + 1 = width of rectangle
s + 3 = length of rectangle
Area of rectangle = (s + 1)(s + 3)
Area of square = [tex]s^{2}[/tex]
So, (s + 1)(s + 3) + [tex]s^{2}[/tex] = 33
[tex]s^{2}[/tex] + 4s + 3 + [tex]s^{2}[/tex] = 33
2[tex]s^{2}[/tex] + 4s - 30 = 0
2([tex]s^{2}[/tex] + 2s - 15) = 0
2(s + 5)(s - 3) = 0
s = -5 or s = 3
Length of a side cannot be negative, so -5 is ignored
3 m = side of the square
4 m = width of the rectangle
6 m = length of the rectangle
2(4) + 2(6) = 8 + 12 = 20 m = perimeter of rectangle
2 x minus 4 y = 8. x + y = 7.

Step-by-step explanation:
An equilateral triangle with side length 9 cm is shown in the diagram, work out the area of the triangle.
Give your answer rounded to 1 DP.
Question:-
Find the area of an equilateral triangle with side length = 9cm correct upto one decimal place.
_______________________________________________
Solution:-
In an equilateral triangle all sides are equal.
Let s = side length = 9 cm
Then, area of equilateral triangle is given as:
A = (√3/4)s²
Putting the value of s here,
A = (√3/4) * (9 cm)²
=> A = (√3/4) * 81 cm²
=> A = √3 * 20.25 cm²
We know that, √3 = 1.732
=> A = 1.732 * 20.25 cm²
=> A = 35.073 cm²
Rounding to one decimal place,
=> A = 35.1 cm²
_______________________________________________
The answer is 35.1 cm².

Answer: D) The balloon
Explanation:
Ignore the "above sea level" and "below sea level" portions. Focus purely on the numbers themselves. The largest value is the furthest away from sea level. The smallest value is closest to sea level.
Therefore, the balloon is furthest from sea level because 27 is the largest of the four values (5, 12, 18, 27).
Match the correct volume equation to each 3-D figure.

What is the equation of this line of best fit in slope-intercept form?
Answer:
C is the right answer
Step-by-step explanation:
I need help please and thank you
Answer:
4
Step-by-step explanation:
The slope of the line is given. It is 4. Use the equation y=mx+b to answer the other questions.
Substitute 1 in for y, 4 in for m, and 2 in for x and solve for b. The equation would look like 1=4(2)+b.
Solving that equation will give you b=-7
That means the y-intercept is -7.
The equation would then be y=4x-7

48% of US adults have very little confidence in newspapers you randomly selected 10 US adults. Find the probability that the number of US adults who have very little confidence in newspapers is exactly 5
Answer:
[tex]P(x = 5) = 0.2441[/tex]
Step-by-step explanation:
Given
[tex]p = 0.48[/tex] --- proportion that have very little confidence
[tex]n = 10[/tex] --- sample
Required
Determine the probability that exactly 5 have very little confidence
This question will be solved using binomial probability:
[tex]P(x) = ^nC_xp^x(1-p)^{n-x}[/tex]
In this case: x = 5.
So, we have:
[tex]P(x = 5) = ^{10}C_5*0.48^5(1-0.48)^{10-5}[/tex]
[tex]P(x = 5) = ^{10}C_5*0.48^5*0.52^5[/tex]
[tex]P(x = 5) = 252*0.48^5*0.52^5[/tex]
[tex]P(x = 5) = 0.2441[/tex]
