If the circumference of a circle is 82p , then the value of ‘r’ is
(i) 41 cm
(ii) 82 cm
(iii) 21 cm
(iv) 20 cm
Answer:
41cm
Step-by-step explanation:
The circumference of a circle is 82π
Therefore r can be calculated as follows
2 × π × r= 82× π
2πr= 82π
r = 82π/2π
r= 41
Hence r is 41cm

Karina owns a bakery where she orders both green apples and red apples to use in her baked goods. The supplier of the green apples says that 8% of their green apples are bruised. The supplier of the red apples says that 6% of their red apples are bruised.
Each week, Karina orders 120 of each type of apple, and she looks at the difference (Green−Red) between the proportions of apples with bruises in each order.
What will be the shape of the sampling distribution of the difference in sample proportions, and why?
A. Approximately normal, because we expect 10 bruised and 110not-bruised in both orders, and all of these counts are at least 10.
B. Approximately normal, because we expect 16 bruised and 104 not-bruised green apples, and 12 and 108 for the red apples, and all of these counts are at least 10
C. Not normal, because we expect fewer than 10 bruised apples in both orders.
D. Not normal, because we expect fewer than 10 not-bruised apples in both orders.
Not normal, because we expect fewer than 10 bruised apples in both orders.
Step-by-step explanation:
Answer: C
Not normal, because we expect fewer than 10 bruised apples in both orders.

Kenny wants to take his dog to obedience school. At Sit and Stay School, 12 lessons cost $96. At Canine Community Center, 25 lessons cost $125. Which is the better deal?
Answer:
25 lessons that cost $125
Step-by-step explanation:
If 8 lessons cost $96
then, 96/12 =8
therefore a lesson costs $8
If 25 lessons costs $125
then, 125/25= 5
therefore a lesson costs $5 which is cheaper.

Identify the vertex of the quadratic function
Answer:
(-2,-1)
Step-by-step explanation:
On the graph, the vertex is where the bottom of the U is. In general, it's always that same place on the U, but the U could be turned upside down or left or right. Looking at the bottom of the U, count on the x axis first (left 2, which is negative). That's your first number. Then count on the y axis (down 1, again, negative). That's your second number.

10x + 18
4x + 8
21x + 65
10x + 8
Part B
If the store owner spent a total of $90 on both orders, how much does a box of light bulbs cost in dollars? Enter the number in the box.

Answer:
Your answer is: X = 11
Your equation: 7x+30=90
If you subtract 7 from 90 you get 77.
If you divide 77 and 7 you get 11.

Answer:
mode: none
median: 4
mean: 4.2
Step-by-step explanation:
when dealing with mean, median, mode the first thing you should do is arrange the numbers in order from least to greatest. Once you have done so the easiest thing to do first is see which number is in the very middle, this is your median. Mode is the number that appears the most. Mean is another word for average. To find the mean, add up all the numbers then divide the sum of all the numbers by how many numbers are listed. In this case, 2+3+4+5+7=21.
21 divided by 5 (how many numbers there are) = 4.2

What is the system of equations?
A system of equations is a collection of one or more equations that are considered together. The system can consist of linear or nonlinear equations and may have one or more variables. The solution to a system of equations is the set of values that satisfy all of the equations in the system simultaneously.
Let's use the given information to set up a system of equations to solve for Ryan's age.
We know that Ryan's age, y, is twice Chaise's age, x, so we can write:
y = 2x (Equation 1)
We also know that Ryan is 11 years older than Chaise, so we can write:
y = x + 11 (Equation 2)
Now we can substitute Equation 1 into Equation 2:
2x = x + 11
Simplifying, we get:
x = 11
So Chaise is 11 years old.
To find Ryan's age, we can use either Equation 1 or Equation 2. Let's use Equation 2:
y = x + 11
y = 11 + 11
y = 22
Therefore, Ryan is 22 years old.

Answer:
y = x + 1
Step-by-step explanation:
The line y = x goes through the origin, and forms a perfect 45 degree angle with the x axis.
This is that same line, moved upward 1 unit, so the y value comes out 1 unit more.
Also, in y = mx + b form (slope-intercept form), we see slope m = 1 and y-intercept b = 1, so
y = 1x + 1 = x + 1
y = x + 1
Raphael deposited $6,500 in an account that pays 4.25% interest, compounded annually. He left the money in the account for 4 years, without depositing money to it or withdrawing money from it. At the end of the 4 years, how much interest in dollars and cents did the account earn? Record your answer and fill in the bubbles on your answer document. Be sure to use the correct place value.
Answer:

I tried, but I'm not a math whiz or anything.
The amount of interest is $1170.
What is the compound interest?Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.
The formula used to find the compound interest = [tex]A=P(1+\frac{r}{100})^{nt}[/tex].
Given that, principal =$6500, rate of interest =4.25% and time period = 4 years.
Here, Amount = 6500(1+4.25/100)⁴
= 6500(1+0.0425)⁴
= 6500(1.0425)⁴
= 6500×1.18
= $7670
Interest = Amount-Principal
= 7670-6500
= $1170
Therefore, the amount of interest is $1170.
