Answer:
There are many ways you could put this let me demonstrate.
Step-by-step explanation:
If they were to do this for a year (52 weeks) that would be 50x52=2600+1000=3600. Then 75x52=$3900+500=$4400. but if you were to cut that time in half to 6 months it would go something like this. 50x26=1300+1000=2300. Then 75x26=1950+500=2450. It all has to do with the time. I hope this helped.

Erica finds a block of cheese in her
fridge. Originally, the block weighed
126 g, but there is only 60% of it left.
How many 10-g wedges can she cut
from the cheese that is left?
8
21
12
7
Answer:
7
Step-by-step explanation:
126 g is what you originally had which=60% of whats left
you have to find out how many 10 wedges she can cut from the cheese that is left over
Work Shown:to find how much is left you have to multiply 126 by 60% remember when you multiply you have to move the decimal, and decimal is moved twice, so the answer would be 75.60 after you were done solving it and the number that is closest would be 70 so you would multiply 10 by 7=70 and the reason you pick that is because it is closer to 75.60.
So 7 is the answer.

Answer:
y = 3x+4
Step-by-step explanation:
slope formula is changes of y over the changes of x
[tex] \large \boxed{m = \frac{y_2-y_1}{x_2-x_1} }[/tex]
m is slope in y = mx+b.
Substitute the coordinate points in.
[tex] \large{m = \frac{7 + 2}{1 + 2} } \\ \large{m = \frac{9}{3}} \\ \large{m = 3}[/tex]
Since we know the slope, we rewrite by substituting m = 3 in the slope-intercept form.
[tex] \large{y = mx + b} \\ \large{y = 3x + b}[/tex]
Then we either substitute one of given coordinate points to find the value of b. I will substitute (1,7) in the equation.
[tex] \large{7 = 3(1)+ b} \\ \large{7 = 3 + b} \\ \large{7 - 3 = b} \\ \large{4 = b}[/tex]
Then rewrite the equation from y = 3x+b by substituting the value of b.
[tex] \large{y = 3x + b} \\ \large{y = 3x + 4}[/tex]

A gym knows that each member, on average, spends 70 minutes at the gym per week, with a standard deviation of 20 minutes. Assume the amount of time each customer spends at the gym is normally distributed. Suppose the gym surveys a random sample of 49 members about the amount of time they spend at the gym each week. What are the expected value and standard deviation (standard error) of the sample mean of the time spent at the gym
Answer:
the expected value and the standard deviation of the sample mean is 70 and 2.86 respectively
Step-by-step explanation:
The computation of the expected value and the standard deviation of the sample mean is shown below:
The mean is 70
And, the standard deviation is
= 20 ÷ √49
= 20 ÷ 7
= 2.86
Hence, the expected value and the standard deviation of the sample mean is 70 and 2.86 respectively

What is arithmetic mean?Arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean. One of the basic methods used to acquire a result, the term "Mean" is commonly used in the field of statistics.
The formula for the mean of a given set of data is as follows:
Mean = Sum of Observations/Total number of observations
Given the frequency distribution as :
People per residence (x) Frequency (f) fx
1 2 1 × 2 = 2
2 4 2 × 4 = 8
3 3 3 × 3 = 9
4 1 4 × 1 = 4
5 1 5 × 1 = 5
6 1 6 × 1 = 6
Summation of fx = (Σfx) = 2 + 8 + 9 + 4 + 5 + 6 = 34
Total frequency = (Σf) = 2 + 4 + 3 + 1 + 1 + 1 = 12
⇒ Mean = Σfx/Σf
⇒ 34/ 12
⇒ 2.83 ≈ 2.8
Thus, the mean of the frequency distribution is 2.8.

What is the area of polygon LMN?

C. 65
D. 70
E.80
Answer:
c:65
Step-by-step explanation:
The area of a triangle can be found almost the same way as a sqaure L*W (Length times width). Except the area of a triangle is one half that of a square, so it is [tex]\frac{1}{2}[/tex]L*W. The length is 13 and the width is 10, so 13*10=130, than 1/2 that is 65.

Maria and Ming start at the same point and drive in opposite directions. Maria drives 54 mph and Ming drives 48 mph. How far apart will they be in 3 hours?
Answer:
Step-by-step explanation:
Remark
They are going in opposite directions. That means you add the distances.
Total Distance = Maria_d + Ming_d
Ming
d = ?
r = 48 mph
t = 3 hour
d = r * t
d = 48 * 3
d = 144 miles
Maria
d = ?
r = 54 miles / hour
t = 3 hours
d = r * t
d = 54 * 3
d = 162
Total distance
Total = 162 + 144
Total = 306 miles
Write the additive inverse and multiplicative inverse of 3-7i?
Step-by-step explanation:
additive inverse means multiplying 3-7i by it's conjugate which would be
(3-7i)(3+7i)=3^2+7^2=9+49=58
the multiplicative inverse of a number z is 1/z
1/(3-7i)
multiply numerator and denominator by 3-7i's conjugate and it equals 58
(3-7i)/58
3/58-7/58i

Chris said that a fraction equivalent to 9/12 is 3/6
Answer:
9/12 is equal to 3/4.
Step-by-step explanation:
9 and 12 can both be divided by 3. In the fraction, divide both the top and the bottom by 3 and you get 3/4.
9/12 simplified is 3/4.
I suspect where Chris went wrong was that he though 9 divided by 2 was 3. In reality, it's 4.5.
Maybe he went wrong because he accidentally divided 12 by 2 instead of 3.
The fraction 9/12 and 3/6 are not equivalent as 91/2 is 3/4.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, Chris said that a fraction equivalent to 9/12 is 3/6.
We know we write fractions in the simplest form.
Now, In the fraction 9/12 we can factor out 3 to both the numerator and the denominator.
Therefore, The fraction 9/12 is equivalent to 3/4.

Consider the angle shown below with an initial ray pointing in the 3-o'clock direction that measures θ radians (where 0≤θ<2π). The circle's radius is 2 units long and the terminal point is (−1.15,−1.64).

Therefore, θ=
Answer:
hello attached below is the sketch of the missing diagram
a) h = 2
b) cos^-1 ( 2 ) = ∞
c ) θ ≈ 215°
Step-by-step explanation:
a) The length ( h ) to the right of the circles center
= h^2 = ( -1.15)^2 + ( -1.64)^2
∴ h = 2
b) cos^-1 ( 2 ) = ∞
c) The value gotten from b does not give us the value of θ
AB = - 1.64
BC = -1.15
AC = 2
sin^-1 ( - 1.64 / -1.15 )
cos^1 ( -1.15 / 2 ) gives us the value of θ
tan^-1 ( -1.64 / -1.15 )
∴ θ ≈ 215°
What is the radius and diameter of the following circle?
16 cm
Answer:
radius is 16
diameter is 32
Step-by-step explanation:
Your radius is the line starting from the point in the middle to any part of the edge of the circle. A diameter is when there is a long straight line from both ends reaching the edges of the circle crossing the point.
A diameter is just the radius doubled but except it all has to be straight coming reaching both edges.
A radius is half of a diameter.
Answer:
radius = 16 cm
diameter = 32 cm
Step-by-step explanation:
radius = a straight line from the center of the circle to any point on the circle's circumference
We are given the radius (16 cm)
The diameter is equal to twice the length of the radius
So diameter = 16 * 2
16*2=32 so the length of the diameter is 32 cm
