Answer:
16 = 16
Step-by-step explanation:
Cross multiplying is when you multiply the numerator and denominator of two fractions.
So, it would be 4 × 4 = 8 × 2 or 16 = 16. This is essentially proving they are equal to one another.
Hope this helps.
Assume that adults have IQ scores that are normally distributed with a mean of ?=100 and a standard deviation ?=20. Find the probability that a randomly selected adult has an IQ less than 140.
Answer:
The probability that a randomly selected adult has an IQ less than 140 is 0.9772
Step-by-step explanation:
Given:
Standard deviation: σ=20
Mean: μ=100
P(X<140)=?
Calculate:
normalcdf(lower,higher,μ,σ) = normalcdf(0,140,100,20) = 0.9772496509 ≈ 0.9772 ≈ 97.72%

Answer:
19.42 ft
Step-by-step explanation:
Triangle Outer Perimeter:
5ft + 5ft = 10ft
Semi-Circle Outer Perimeter:First let's find the circumference of the entire circle:
Circumference = 2πr
Circumference = 2π * 3
Circumference = 6π
Circumference = 6(3.14)
Circumference = 18.84
Now to find the perimeter of the semicircle, we divide that value by two:
6π = 18.84
(6π)/2 = (18.84)/2
3π = 9.42 ft
Total Outer Perimeter:10 ft + 9.42 ft = 19.42 ft

The equation y = 18x describes the amount of money Spongebob earns as a fry cook, where x is the
number of hours he works and y is the amount of money he earns. Show work. Complete sentence.
The table shows the amount of money Squidward earns as a cashier for different numbers of hours worked.
Squidward’s Earnings
Time (h) 3 5 8 10
Money earned
($) 48 80 128 160
(a) How much money does Spongebob earn per hour?
(b) How much money does Squidward earn per hour?
pls help and explain
Answer:
a. 18 dollars per hour
b. 16 dollars per hour
Step-by-step explanation:
for a, 18 is the slope of y=18x, meaning spongebob earns 18 dollars per hour
for b, since it seems like squidward earns 32 dollars every 2 hours, it can be guessed that he earns 16 dollars per hour, since 32/2 = 16

x + 4y = 23
-2x + 3y = -2
Answer:
(x, y) = (7, 4)
Step-by-step explanation:
I find a graphing calculator to give a solution quickly and easily.
(x, y) = (7, 4)
__
Here, we can solve the first equation for x, then substitute into the second.
x = 23 -4y
-2(23 -4y) +3y = -2 . . . . . substitute for x
-46 +8y +3y = -2 . . . . . eliminate parentheses
11y = 44 . . . . . . . . . . . collect terms
y = 4 . . . . . . . . . . . . divide by the coefficient of y
x = 23 -4·4 = 7 . . . . use the expression for x to find x
(x, y) = (7, 4)
A toy rocket is launched from a platform 33 feet above the ground at a speed of 83 feet per second. The height of the rocket in feet is given by the polynomial −16t2 + 83t + 33, where t is the time in seconds. How high will the rocket be after 3 seconds?
a. 2586 feet
b. 234 feet
c. 138 feet
d. 105 feet
Answer:
c. 138 feet
Step-by-step explanation:
h(t) = −16t^2 + 83t + 33
At3 seconds
h(3) = -16(3^2) + 83(3) + 33
h(3) = -16(9) + 249 + 33
h(3) = -144 + 249 + 33
h(3) = 138
c. 138 feet

how do I determine what a function is for a line graph
Answer: Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

Factor the following polynomial x^2-9
Answer:
(x+3)(x-3)
Step-by-step explanation:
We know that [tex](a+b)(a-b)=a^2+b^2\\[/tex]
So, here we have x² and 9, which can be written as 3².
Therefore, we can have x=a and 3=b
So we get
(x+3)(x-3)
To check that we are correct, we can expand the brackets:
x²-3x+3x-9
=x²-9
