Answer:
89.44%Step-by-step explanation:
Find the z-score:
z = (x - μ) / σz = (65 - 70) / 4 = -1.25From the z-score table we get corresponding value of 0.1056
Proportion of scores higher than Cam's score:
1 - 0.1056 = 0.8944 = 89.44%Answer:
A set of chemistry exam scores are normally distributed with a mean of 70 points and a standard deviation of 4 points. Cam got a score of 65 points on the exam. What proportion of exam scores are higher than Cam's score? (hint the z score taken from the z score chart linked below will be the number of scores below Cam's. We are looking for the number of scores higher than Cam's Score. This is 1 - z score)

Find the value of x need ASAP
Answer:
x=75°
Step-by-step explanation:
the triangle is an isosceles triangle (which you can tell since they show you that the two sides are congruent)
so this means that the base angles are congruent
so, x=75°

Answer:
f(5) = 2
Step-by-step explanation:
it says to use the function (-x+3) for when x is bigger than 2
f(x) = (-x) + 3 replace x with 5
f(5) = (-5) + 3 and f(5) = 2
Answer:
[tex]f(5)=-2[/tex]
Step-by-step explanation:
In piecewise functions, we need to find the applicable equation to use based on our value of [tex]x[/tex]. [tex]f(5)[/tex] denotes [tex]x[/tex] as 5. Since [tex]5>2[/tex], we will use the equation that corresponds to [tex]x>2[/tex], which is [tex]-x+3[/tex].
Substituting [tex]x=5[/tex], we have:
[tex]x=-(5)+3,\\x=-5+3,\\x=\boxed{-2}[/tex]
Match each equation with the problem it represents.
Answer:
4 more than the product of 9 and a number is 36. /// 9n + 4 = 36
9 times the sum of a number and 4 is 36. /// 9(n + 4) = 36
4 times the sum of a number and 9 is 36. /// 4(n + 9) = 36
9 subtracted from the product of 4 and a number is 36. /// 4n - 9 = 36

Step-by-step explanation:
m<UZV = 180-108=72°
arc YVU = 180+72+85= 337°
diameter XV = 24 m
so, the length of arc YVU =
337/360 × π × D
= 0.94 × 3.14 × 24 m
= 70.84 meters

A number of two digits is increased by 54 when the digits are reversed. The ten digits is three times the unit digit. Find the number
Let n be the unknown number. We can write it as
n = 10a + b
with a and b integers between 1 and 9 (either with positive or negative sign).
Reversing the digits gives another number
m = 10b + a
The first number is increased by 54 when the digits are reversed, which means
m = n + 54 → 10b + a = 10a + b + 54 → 9b - 9a = 54 → b - a = 6
The digit in the tens place of n is 3 times the digit in the ones place, so
a = 3b
Substitute this into the previous equation and solve for b :
b - a = b - 3b = -2b = 6 → b = -3
Solve for a :
a = 3b = 3(-3) = -9
Then the original number is n = 10a + b = 10(-9) + (-3) = -93
Tyler asks for a fish tank for his birthday. The task he wants is a rectangular prism 20 inches long, 10 inches wide, and 12 inches tall.
Answer:
2400 in^3
Step-by-step explanation:
Tyler asks for a fish tank for his birthday. The task he wants is a rectangular prism 20 inches long, 10 inches wide, and 12 inches tall. How much water will the fish tank hold?
the capacity of the tank can be determined by calculating the volume of the tank
volume of a prism = length x width x height
20 x 10 x 12 = 2400 in^3

2x + 5 /3x + 7 = 3/5 find X plz
Answer:
x = -96/55
Step-by-step explanation:
Given that 2x + (5 /3)x + 7 = 3/5
Firstly, we have to multiply through out the expression by the common denominator. We can see that the denominators are 3 and 5, hence the common denominator is 15. Multiplying through by 15 gives:
2x * 15 + (5 /3)x * 15 + 7 * 15 = (3/5) * 15
30x + 25x + 105 = 9
Collect like terms:
30x + 25x = 9 - 105
55x = -96
Dividing through by 55:
x = -96/55

Step-by-step explanation:
Answer:
The cube of first six natural numbers are
1, 8, 27, 65, 125, 216
Step-by-step explanation:
Natural Numbers are known as 1, 2, 3, 4, ..., ∞
Now,
For Cube of first six natural numbers
1³ = 1
2³ = 8
3³ = 27
4³ = 64
5³ = 125
6³ = 216
Thus, The cube of first six natural numbers are
1, 8, 27, 65, 125, 216
