Answer:
87% would be faster than 58 seconds
Step-by-step explanation:
Landon runs the 400 meter dash, his finishing times are normally distributed with a mean of 60 seconds and a standard deviation of 1 second
[tex]\mu = 60[/tex]
Standard deviation =[tex]\sigma = 1[/tex]
We are supposed to find Landon were to 38 practice trials of the 400 meter dash , how many of those trials would be faster than 58 seconds , to the nearest whole number i.eP(x<58)
[tex]Z=\frac{x-\mu}{\sigma}\\Z=\frac{58-60}{1}\\Z=-2[/tex]
Refer the z table for p value
P(x<58)=0.0228
Landon were to 38 practice trials
So, P(x<58)=[tex]38 \times 0.0228=0.8664[/tex]
So, 86.64% would be faster than 58 seconds
Hence 87% would be faster than 58 seconds

Jennifer and Roger both keep herds of sheep. Jennifer’s herd has 12 more sheep than does Roger’s herd, and the combined total of sheep in Jennifer’s and Roger’s herd is 64. How many sheep are in Jennifer’s herd?
Answer:
38
Step-by-step explanation:
Let Roger be x
12+x + x = 64
12 + 2x = 64
2x = 64-12
x = 52/2 = 26
Jennifer will be 12 + 26 = 38

A rectangle has a length of 8 inches
and a width of 6 inches.
What is the area of the rectangle?
Answer:
A = 48 inches ^2
Step-by-step explanation:
The area of a rectangle is found by
A = lw
A = 8* 6
A = 48 inches ^2
We can find the area of the rectangle using the formula below.
Area = length × width
Since the length is 8 inches and the width is 6 inches, we can plug this information into the formula to get (8 in.)(6 in.)
which simplifies to 48 in.².
So the area of the rectangle is 48 in.².

Answer:
402 cm.
Step-by-step explanation:
To find this, we will need to calculate the circumference of the reel. We can do this using the formula [tex]C = d\pi[/tex].
Since the radius is 4 cm, the diameter is 8 cm. Put this into the equation to solve for the circumference:
[tex]C = 8\pi = 25.12[/tex]
Since the reel spun 16 times, simply multiply the circumference by 16 to get:
25.12 × 16 = 401.92
≈ 402 cm.
What is |a| + |b + c| when a = - 4 , b = 2 , and c = - 7 ?
Answer:
9
Step-by-step explanation:
Rule => if ''a'' is negative, |a| = -a|0| = 0absolute value means how far a number from 0if we don't know anything about x,and x equals to a. We can say |x| = a and |-x| = a....So , x or -x equals a . But both of x aren't equals a, one of them is same|a| + |b + c| = |-4| + |2 + (-7)|
|-4| = -(-4) = +4
|2 + (-7)| = |-5|
|-5| = -(-5) = +5
4 + 5 = 9

An experienced landscaper thought it would be funny to play a joke on some rookie landscapers. The rookies were given the measurements, length=4 cube root of 24ft and width=6 cube root of 3ft, and asked to find the exact area (no decimals) of the rectangular region they would be working with. Show the equation and all work needed to find the exact area in simplest form (no decimals). Be sure to write a sentence explaining your answer. Don’t forget the label!
Answer:
48∛9 ft²
Step-by-step explanation:
Data
length = 4 ∛24 ft width = 6 ∛3 ftThe area of the rectangular region is computed as follows:
area = length * width
area = 4 ∛24 * 6 ∛3
area = 4*6* ∛(24*3)
area = 24 * ∛(2³*3*3)
area = 24 * 2∛9
area = 48∛9 ft²
What is the solution to the equation 5 x = 32?
a. x = 6
b. x = 6.4
c. x = 27
d. x = 160
Answer
x = 32/5 = 6.400
Answer is B
Step-by-step explanation:
1: Rearrange
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation
Solving a Single Variable Equation
Solve : 5x-32 = 0
Add 32 to both sides of the equation :
5x = 32
Divide both sides of the equation by 5:
x = 32/5 = 6.400
The correct answer is B.
Answer: x = 32/5 = 6.400
Hope this helps.
Answer:
B
Step-by-step explanation:
5x=32 move the 5 over by dividing
x=5/32. 5 divided by 32 equals 6.4

Name a game or sport in which parallel lines are important in game play and/or scoring
Answer: FOOTBALL
Step-by-step explanation:
Angles play a crucial role in football, from a pass or kick, to the way players move and how plays are called. Football players can even use angles to enhance their individual or team performance. For example, a football placekicker must know what angle to kick the ball at to score a field goal. The path the football will take once it’s kicked comes down to the angle at which it is kicked, the amount of force applied, and the height of the kick. When kicking from thirty yards away, a larger angle is necessary to get the ball through the goalpost. However, when making a fifty yard kick, a shorter angle is called for, so the ball can travel the greater distance to the goal. When the opposing team is trying to block the kick, a higher angled kick is necessary.

Step-by-step explanation:
CYLINDER VOLUME: A (area) = π x r (radius) ^2
A = π (5)^2
A= 25 π
THEN
You need 5 (the radius) twice so 5^2 which equals 25
2 x π x r^2 (BUT WITH 25) → 2 x 25 π ^2
2 x π x r^2 (BUT WITH ORIGINAL RADIUS 5) → 2 x π(5)
Now multiply 25 x height →25 x 10.6 = 265
2 x 25 π ^2 + 265
2 x 25 = 50 + 265 = 315 π ^2

If f(x) = 2x2 and g(x)= x2 + 2x, which expression represents f(g(x))?
Answer:
f(g(x)) = 2(x^2 + 2x)^2
f(g(x)) = 2x^4 + 8x^3 + 8x^2
Step-by-step explanation:
Given;
f(x) = 2x^2
g(x) = x^2 + 2x
To derive the expression for f(g(x)), we will substitute x in f(x) with g(x).
f(g(x)) = 2(g(x))^2
f(g(x)) = 2(x^2 + 2x)^2
Expanding the equation;
f(g(x)) = 2(x^2 + 2x)(x^2 + 2x)
f(g(x)) = 2(x^4 + 2x^3 + 2x^3 + 4x^2)
f(g(x)) = 2(x^4 + 4x^3 + 4x^2)
f(g(x)) = 2x^4 + 8x^3 + 8x^2
Hope this helps...
