Answer:
270°
Step-by-step explanation:
a reflex angle is an angle which is larger than 180° but smaller than 360°
an angle around a point is 360°
so to find angle B we do [tex]360-90[/tex] to give 270
so angle B is 270°
If cookies sell for $1 and oranges for 75 cents, how many of each were sold for a total of $8.25?
Answer:
To make total 8.25 we need to take number of oranges in such a way that they always make . 25 in total. Only then we can get 8.25 as total because cookies will always give integers.

supposed normal distribution has a mean of 89 and a standard deviation of 7. What is P(x≤82)? NO LINKS!!!
a. 0.975
b. 0.84
c. 0.16
d. 0.025
======================================================
Explanation:
Convert the x = 82 to a corresponding z score.
z = (x-mu)/sigma
z = (82 - 89)/7
z = -7/7
z = -1
Using the empirical rule (see chart below), roughly 68% of the distribution is within 1 standard deviation of the mean.
This leaves 1 - 0.68 = 0.32 = 32% of the distribution in both tails, and (32%)/2 = 16% of the area is in one tail, which converts to 0.16
About 16% of the normally distributed population is below z = -1.
So we can say [tex]P(x \le 82) = P(z \le -1) \approx 0.16[/tex]
z value:-
[tex]\\ \rm\Rrightarrow \dfrac{x-\overline{x}}{\sum}[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{82-89}{7}[/tex]
[tex]\\ \rm\Rrightarrow \dfrac{-7}{7}[/tex]
[tex]\\ \rm\Rrightarrow -1[/tex]
z=-1As per z value chart
Part distributed to z=-1 is 32%/2=16%=0.16Option C is correct

Answer:
If we classify the shapes shown in the picture, we can see that there are 4 triangles and one square.
First, we need to find out the formulas for the areas of these shapes.
Formula for area of triangle;
A = BH x 1/2
where b represents the base, and h represents the height
Formula for area of square;
A = a^2
where 'a' represents the length of one side of a square
Now we just plug in the actual values to these formulas:-
(Finding area of square first)
A = a^2
A = 2^2
A = 4
Now, we find the area of one triangle and multiply it by 4 because there are four of each of those triangles.
A = BH x 1/2 x 4(no. of triangles)
A = 2(3) x 1/2 x 4
A = 6 x 1/2 x 4
A = 6/2 x 4
A = 3 x 4
A = 12
Now we add the two areas together;
4 + 12 = 16 square feet

-15+3y=9 solve for y
Answer:
y=8
Step-by-step explanation:
Answer:
Y = 8
Step-by-step explanation:
To solve this equation, you must isolate the variable (y).
To do this, let's add 15 to both sides.
-15+3y = 9
+15 +15
3y = 24
Then, we need to divide each side by 3, in order to get y alone.
y = 8
Part A. Find the domain and range
Part B. Which set of coordinates describes a function?
A.{( 6,3), (4,5), (2,3), (0,5)}
B.{( 4,-3),(-4,-6),(4,3),(-4,6)}
C.{(2,4), (4,8), (6,2)}
D.{(-5,-1), (-3, -3), (-1, -5),(-5,-7)}
Answer:
d. {(-2, 5), (-1, 2), (0, 1), (1, 2), (2, 5)}; Domain: {-2, -1, 0, 1, 2}; Range: {1, 2, 5}
Step-by-step explanation:
Part A:
Domain = the set of all x-values plotted on the x-axis = {-2, -1, 0, 1, 2}
Range = the set of all possible y-values on the y-axis that corresponds with the x-values = {1, 2, 5}
Part B:
The set of coordinates that describes the function on the graph are:
When x = -2, y = 5 => (-2, 5)
When x = -1, y = 2 => (-1, 2)
When x = 0, y = 1 => (0, 1)
When x = 1, y = 2 => (1, 2)
When x = 2, y = 5 => (2, 5)
The set of coordinates is:
{(-2, 5), (-1, 2), (0, 1), (1, 2), (2, 5)}

A major grocery store chain is trying to cut down on waste. Currently, they get peaches from two different distributors, WholeFruits and GreenGrocer. Out of two large shipments, the manager randomly selects items from both suppliers and counts the number of items that are not sell-able due to bruising, disease or other problems. She then makes a confidence interval. Is there a significant difference in the quality of the peaches between the two distributors
There is a significant difference in the quality of the peaches between the two distributors because:
We are 95% confident that the proportion of non sell-able items for Whole Fruits is anywhere between 0.064 and 0.156 HIGHER than the proportion of non sell-able items for Green Grocer.What does confidence interval of 95% mean?A confidence interval is a term that connote an estimate (plus or minus) the variation that may be seen in that specific estimate.
A 95% confidence interval implies that if a person do a research such as (two different distributors, e.g. WholeFruits and GreenGroce) and took 100 different samples and then compute a 95% confidence interval for each sample, it therefore means that about 95 of the 100 confidence intervals will hold the true mean value (μ).
See options below
We are 95% confident that the proportion of non sell-able items for Whole Fruits is anywhere between 0.064 and 0.156 LOWER than the proportion of non sell-able items for Green Grocer.
We are 95% confident that the proportion of non sell-able peaches for Whole Fruits is about -0.064 and 0.156.
We are 95% confident that the proportion of non sell-able items for Whole Fruits is anywhere between 0.156 LOWER and 0.064 HIGHER than the proportion of non sell-able items for Green Grocer.
We are 95% confident that the proportion of non sell-able peaches from Whole Fruits is anywhere between 0.064 and 0.156.

One-fifth of an even number added to one-sixth of the next even number makes a total of 15. find the two numbers
(Hint: let the number be x and x + 2.)
Answer:
40 and 42
Step-by-step explanation:
Let the two even numbers be x and x+2.
"One-fifth of an even number:" (1/5)x
"one-sixth of the next even number:" (1/6)(x+2)
Added they make 15: (1/5)x + ((1/6)(x+2)) = 15
(1/5)x + ((1/6)(x+2)) = 15
(1/5)x + (1/6)x+(1/6)*2 = 15
(1/5)x + (1/6)x+(2/6) = 15
(6/30)x + (5/30)x = 15 - (1/3)
(11/30)x = (45/3) - (1/3)
(11/30)x = (44/3)
x = (30/11)*(44/3)
x = 40
x + 2 = 42
