[tex]\sf X \sim N(\mu, \sigma^2)[/tex]
Given:

Part A[tex]\begin{aligned}\sf P(180 < X < 190) & = \sf P(X < 190)-P(X\leq 180)\\& = \sf 0.4588035995-0.03380583874\\& = \sf 0.4249977608\end{aligned}[/tex]
Total number of bodybuilders = 1500
Therefore, the number of bodybuilders between 180 and 190 pounds is:
[tex]\begin{aligned}\sf P(180 < X < 190) \cdot1500 & = \sf 0.4249977608 \cdot 1500\\& = \sf 637.4966412\\& = \sf 637\end{aligned}[/tex]
Part B[tex]\begin{aligned}\sf P(X > 195) & = \sf 1-P(X\leq 195)\\& = \sf 1-0.7759602537\\ & = \sf 0.2240397463\\ & = \sf 0.2240\:(4\:dp)\end{aligned}[/tex]
2 . Using the slope-intercept form of a line, find the equation of the line with slope and y-intercept-2. Then graph the line on the grid provided and explain how you determined your graph
Answer:
see below
Step-by-step explanation:
slope intercept form slope = -2 y axis intercept = -2
y = -2x - 2 to graph this pick two values of x say -3 and + 2
plug these values into the equation to find the corresponding y values, plot the points and then draw a line connecting them
The product of two consecutive positive integer is 306. We need to find the Integers.
Hope you guys are help me.
Answer:
Let the given set of integers be n and (n+1)
n(n+1)=306
n to the power square +n−306=0

7) Mofor invests $3,101 in a savings account
with a fixed annual interest rate
compounded 2 times per year. After 6
years, the balance reaches $3. 932. 82.
What is the interest rate of the account?
Answer:
4%
Step-by-step explanation:
[tex]A = P(1+r/n)^{nt}[/tex]
A = final amount
P = initial amount
r = interest rate per time period
n = number of times compounded per time period
t = number of time period
A = 3932.82
r = what we want to find
n = 2
t = 6
[tex]A = P(1+r/n)^{nt}\\3932.82 = 3101(1+r/2)^{12}[/tex]
divide both sides by 3101 to isolate the exponent and its parts
[tex]3932.82/3101 = (1+r/2)^{12}[/tex]
put both sides to the power of (1/12) to help isolate the variable
[tex](3932.82/3101)^{1/12}= (1+r/2)[/tex]
subtract 1 from both sides to isolate the variable and its coefficient
[tex](3932.82/3101)^{1/12}-1= (r/2)[/tex]
multiply both sides by 2 to get r
[tex]((3932.82/3101)^{1/12}-1) * 2= r[/tex]
r ≈ 0.04 = 4%

Complete the point-slope equation of the line through (3,6) and (5,-8)
Answer:
y = - 7x + 17
Step-by-step explanation:
Given, (3,6) and (5,-8)
Equation of a straight line is y = mx + c
Here, y = -8, x = 5 and m = ?
m = [tex]\frac{Change in Y}{Change in X}[/tex]
m = [tex]\frac{-8 - 6}{5 - 3}[/tex]
m = - 7
Substituting x, y and m in y = mx + c we get,
- 8 = - 7(5) + c
c = 35 - 8
c = 17
The equation is y = - 7x + 17 (Answer).
Can someone help with trigonometry? 12 points
Answer:
A° = 44.42°
Step-by-step explanation:
Soh Coh Toa
Soh: sin(theta) = Opp/Hyp
Coh: cos(theta) = Adj/Hyp
Toa: tan(theta) = Opp/Adj
We are using Coh: cos(theta) = Adj/Hyp because we need to find Angle A and that 5 is Adjacent and 7 is the Hypotenuse.
cos(A°) = 5/7
A° = cos^-1 (5/7)
A° ≈ 44.4153086
A° = 44.42°

Which graph represents f(x)=4sin(2πx)?
The function f(x)=4sin(2πx) is a sinusoidal function
The graph of the function f(x)=4sin(2πx) is graph (c)
How to determine the graph of the function f(x)=4sin(2πx)?The parent function of a sine function is
f(x) = sin(x)
The function f(x)=4sin(2πx) implies that the parent function f(x) = sin(x) has been horizontally and vertically stretched
So, the graph of the function f(x)=4sin(2πx) would have a higher amplitude and shorter period than its parent function
Hence, the graph of the function f(x)=4sin(2πx) is graph (c)

Their difference is 256 - 16 = 240.
what is (3x + 4)(5x − 2)
Answer:
15x² + 14x - 8
Step-by-step explanation:
Apply the distributive property by multiplying each term in (5x - 2) by each term in (3x + 4).
5x(3x) + (-2)(3x) + 5x(4) + (-2)(4)
= 15x² - 6x + 20x - 8
Combine like terms:
15x² + 14x - 8
(3x + 4)(5x − 2) is the factored form of 15x² + 14x - 8.

Answer:
y = [-2]x - 1
Step-by-step explanation:
y = [-2]x - 1 will make the lines perpendicular.
Because the product of slopes of perpendicular lines is -1

Use the drop down-menus to complete the sentences. when parallel light rays exit a concave lens, they . when parallel light rays exit a convex lens, they .
Answer:
When parallel light rays exit a concave lens, they
✔ diverge
.
When parallel light rays exit a convex lens, they
✔ converge
.
Step-by-step explanation:
The requried, parallel light rays diverge when passing through a concave lens, and converge when passing through a convex lens.
What is reformation?Refraction is the bending of light as it passes from one medium to another medium of different optical densities, such as from air to water or from air to a glass lens.
When parallel light rays exit a concave lens, they diverge as the concave lens is thinner at the center and thicker at the edges. This shape causes the light rays to bend away from the optical axis and spread apart from each other, resulting in a virtual image that is smaller than the object.
On the other hand, when parallel light rays exit a convex lens, they converge towards a focal point as the lens is thicker at the center and thinner at the edges. This shape causes the light rays to bend towards the optical axis and meet at a focal point, resulting in a real image that is inverted and can be larger or smaller than the object depending on the distance of the object from the lens.
Therefore, the behavior of parallel light rays upon exiting concave and convex lenses is quite different due to their distinct shapes and curvatures, resulting in opposite effects on the direction of light rays and the formation of images.

Drake and Evan are teammates on a high school swim team drake swim 312. 63 m during practice evan swim exactly 1/3 times farther than drake exactly how far did Evan swim?
Answer:
416.84 m
Step-by-step explanation:
First Step:
Multiple 312.63 by 1/3
312.63*1/3=104.21
Second Step:
Add 312.63 to 104.21

In this question, we have been provided that Evan swims 1/3 times farther than Drake, thus, the total distance covered by Evan will be equal to the sum of 312.63 m and the 1/3rd of 312.63 m. Thus, at first we will calculate the one third of the distance and then add them up to get our final answer.
