Answer:
x = -8
Step-by-step explanation:
slope of y = 1/6 is zero
the negative reciprocal of zero is considered to be 'undefined', which is the slope of x=-8 (or x = 'any number')

Which statement is most likely to be true for this distribution?
A. The mean is the same as the median.
B. The mean is less than the median.
C. The mean is greater than the median.
Answer:
B
Step-by-step explanation:
The distribution is skewed to the left (the lower end is pulled out to the left). The mean is less than the median. If the distribution were even more skewed to the left the mean would decrease, but the median (middle number in the data) would stay the same.
Sophie has 7 cookies she wants to share equally with ten friends at her party. Part A If she separates all of the cookies and gives each friend an equal amount, how much cookie will each friend receive? Part B If Sophie wanted to give each friend 1 1/2 cookies, how many more cookies would she need?
Answer:
Each friend gets 0.7 cookie
8 cookies
Step-by-step explanation:
A.
Number of cookies = 7
Number of friends = 10
how much cookie will each friend receive?
Number of cookie each friend get = number of cookies / number of friends
= 7/10
= 0.7 cookie
Each friend gets 0.7 cookie
B.
If each friend 1 1/2 cookies
how many more cookies would she need?
Total number of cookies needed = 1 1/2 × 10
= 3/2 × 10
= 30/2
= 15 cookies
She already has 7 cookies
Number of cookies needed more = 15 cookies - 7 cookies
= 8 cookies

According to the line plot what is the total amount of time spent studying by all students who studied 1/4 hour or 3/4 hour
Answer:
2 3/4 hours
Step-by-step explanation:
We see from the figure that 2 students spent 1/4 hours and 3 students spent 3/4 hours.
So the total time spent is
2* (1/4) + 3(3/4) hours
= 1/2 + 9/4
=(2+9)/4 taking l.c.m
= 11/4
= 2 3/4 hours
The total time spent by 5 students on 1/4 hours and 3/4 hours is 2 and 3/4 hours.

Answer:
Volume = 120 cubic cm
Step-by-step explanation:
We would apply the formula for determining the volume of a square bases pyramid which is expressed as
Volume = 1/3 x base area x height
From the diagram,
length of square base = 6 cm
The base area = 6^2 = 36
height = 10
Thus,
Volume = 1/3 x 3/6 x 10
Volume = 120 cubic cm

Can anyone explain how you graph things for example, like y=x-4 how would you graph that
Answer:
In basicallity if a question such as this pops up, the correct way to go would first be to graph this. y=x-4 would be equivalent to x=4.
My paper work is below:
y = x - 4
0 = x - 4
-x = -4
x = 4

In ΔPQR, the measure of ∠R=90°, the measure of ∠P=26°, and PQ = 8.5 feet. Find the length of QR to the nearest tenth of a foot.
Answer:
3.7feet
Step-by-step explanations
Using the sin rule
A/sin a = B/sin b
Let A = PQ = 8.5feet
B = QR = x feet
a = R = 90°
b = P = 26°
Substitute the values into the Sin rule
8.5/sin90 = x/sin26
8.5×sin 26 = x × sin 90
8.5×0.4383 = x× 1
3.7255 = x
Hence the length of QR to the nearest tenth 3.7feet
Evaluate the function for an input value of 3. f(x)= −4x 2 −3x−5
Answer:
- 50
Step-by-step explanation:
x = 3
f ( x ) = - 4x^2 - 3x - 5
f ( 3 )
= - 4 ( 3 )^2 - 3 ( 3 ) - 5
= - 4 ( 9 ) - 3 ( 3 ) - 5
= - 36 - 9 - 5
= - 50

What is the sign of the product (3)(−25)(7)(−24)? (10 points)
Group of answer choices
Positive, because the products (3)(−25) and (7)(−24) are positive, and the product of two positive numbers is positive
Negative, because the products (3)(−25) and (7)(−24) are positive, and the product of two positive numbers is negative
Negative, because the products (3)(−25) and (7)(−24) are negative, and the product of two negative numbers is negative
Positive, because the products (3)(−25) and (7)(−24) are negative, and the product of two negative numbers is positive

a. Write a sinusoidal function that models Omaha's monthly temperature variation
b. Use the model to estimate the normal temperature during the month of April.
Answer
[tex]y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49[/tex]
Step by Step Explanation
Given
See attachment for table
Required
Determine the sinusoidal function
The sinusoidal function is represented as:
[tex]y = A \sin(Bx + C) + D[/tex]
Where
[tex]|A| = Amplitude[/tex]
And it is calculated as:
[tex]A = \frac{1}{2}[Highest - Least][/tex]
From the table:
Highest = 77 and Least = 21
So:
[tex]A = \frac{1}{2}[77 - 21][/tex]
[tex]A = \frac{1}{2}[56][/tex]
[tex]A = 28[/tex]
B is calculated as:
[tex]Period = \frac{2\pi}{B}[/tex]
The period is 12 i.e. 12 months
So:
[tex]\frac{2\pi}{B} = 12[/tex]
[tex]B = \frac{2\pi}{12}[/tex]
[tex]B = \frac{\pi}{6}[/tex]
C is calculated as:
[tex]\frac{C}{B} = -4[/tex]
[tex]C = -4 * B[/tex]
[tex]C = -4 * \frac{\pi}{6}[/tex]
[tex]C = -2 * \frac{\pi}{3}[/tex]
[tex]C = -\frac{2\pi}{3}[/tex]
Lastly, D is calculated as:
[tex]D = Least + A[/tex]
So:
[tex]D =21 + 28[/tex]
[tex]D=49[/tex]
So, the function is:
[tex]y = A \sin(Bx + C) + D[/tex]
[tex]y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49[/tex]
Answer:
y=28 sin (pi/6 t - 7pi/6)+49

HELP NEEDED!!! 20 POINTS FOR A ANSWER AND EXPLANATION ON QUESTION #2! I cant figure this out help me please
Step-by-step explanation:
Start at the orgin.
The y intercept in the equation is -1 so I would shift 1 unit down to the orgin at (0,-1)
Then at the point, since the slope is -4. I would go down -4 units then go over 1 unit to the right.. So the next point would be (1,-5) then so on and so on.
You can check if your graph is correct by writing out specific points on the linear equation and making sure there slope is equal to -4.
I am a 2-digit number. If sum of my two digits is added to the product of my digits, it is me again. Can you find me?
Answer:
Step-by-step explanation:
Let “ab” represent the digits of the number.
a ≠ 0
Value of the number = 10a+b
a+b + ab = 10a + b
a + ab = 10a
ab = 9a
b = 9
“ab” = 19, 29, 39, 49, 59, 69, 79, 89, 99
Answer: 49
Step-by-step explanation:
4x9=36
4+9=13
36+13=49
