When Avani goes bowling, her scores are normally distributed with a mean of 145 and a standard deviation of 12. Using the empirical rule, determine the interval that would represent the middle 68% of the scores of all the games that Avani bowls.
Answer:(133,157)
Step-by-step explanation:
Using the empirical rule, the interval that would represent the middle 68% of the scores of all the games that Avani bowls is (133, 157).
What is Empirical Rule?Empirical rule is a rule for normally distributed data which defines that almost all the data observed ranges between three standard deviations from the mean.
Here, the scores of Avani is normally distributed.
Mean, μ = 145
Standard Deviation, σ = 12
By the Empirical rule, about 68% of the data falls within one standard deviation.
That is, in the interval μ ± σ.
Interval is (μ - σ, μ + σ) = (145-12, 145+12) = (133, 157)
Hence the interval is (133, 157).

A book sold 42,000 copies in its first month of release. Suppose this represents 9.6 of the number of copies sold to date. How many copies have been sold to date?
Answer: 437,500 copies
Step-by-step explanation:
42,000 copies were sold in the first month and this is 9.6% of the total that have been sold till date:
To find the total that have been sold till date, assume the amount to be x.
Expression will be:
9.6%x = 42,000
x = 42,000 / 9.6%
x = 42,000 / 0.096
x = 437,500 copies
437,500 copies have been sold to date.

Find the x-intercept(s) and the coordinates of the vertex for the parabola y=x + 2x-15. If there is more than one x-intercept, separate them with commas,
Step-by-step explanation:
y = x^2 + 2x - 15
To find the x-intercepts, factor out the right side:
y = x^2 + 2x - 15
= (x + 5)(x - 3)
This means that the x-intercepts are at (-5, 0) and (3, 0).
Method 1:
The x-coordinate of the vertex of a parabola is given by the following:
x = -b/2a, where a = 1 and b = 2
= -(2/(2×1))
= -1
Using this value of x gives y = -16
Therefore, the coordinates of the vertex is (-1, -16).
Method 2:
We can find the x-coordinate of the vertex by taking the derivative of y and equating it to zero:
y' = 2x + 2 = 0 ---> x = -1
Using this value of x into our equation, we get y = -16.
Therefore,
vertex: (-1, -16)

Ms. Garcia burns 236 calories riding her bike each
hour. She wants to burn more than 354 calories
riding her bike at the same rate.
Which inequality represents all possible values for
t, the number of hours Ms. Garcia must ride her
bike to burn more than 354 calories?
A t < 1.5
B t > 1.5
C t < 0.5
D t > 0.5
The inequality that represents all possible values for t is:
t > 1.5
Which inequality is the correct one?
We know that she burns 236 calories per hour, so if she rides for t hours, she burns a total of:
t*236 calories.
Now, she wants to burn more than 354, so we have the inequality:
t*237 > 354
Solving for t (by dividing both sides by 237) we get:
t > 354/237 = 1.5
t > 1.5
So the correct option is B.

Jose is trying to pick out an outfit for the first day of school. He can choose from 2 pairs of pants, 6 t-shirts, and 3 pairs of shoes. How many different outfits does Jose have to choose from?
Jose has to choose from 36 different ways.
What is the Combination?The various ways in which objects from a set may be selected, generally without replacement to form subsets is known as combination.
For the given situation,
Pairs of pants = [tex]2[/tex]
T-shirts = [tex]6[/tex]
Pairs of shoes = [tex]3[/tex]
The formula to find the number of ways using combination = [tex]nC_{r}[/tex]
Number of ways of picking the outfit = [tex](2C_{1}) (6C_{1}) (3C_{1} )[/tex]
⇒ [tex](2)(6)(3)[/tex]
⇒ [tex]36[/tex]
Hence we can conclude that Jose has to choose from 36 different ways.

Javier made 180 cupcakes. Each cupcake is covered with frosting. • 1/3 of the cupcakes have vanilla frosting. • 1/10 of the cupcakes have lemon frosting. • 2/5 of the cupcakes have chocolate frosting. • the rest have strawberry frosting. How many cupcakes have strawberry frosting
Answer:
30 strawberry cupcakes
Step-by-step explanation:
180 cupcakes in total
1/3 of 180 - 60 = vanilla
1/10 of 180- 18 = lemon
2/5 of 180 - 72 = chocolate
rest of 180 - 180-(72+18+60) = strawberry
rest of 180 - 180-150 = 30 = strawberry
Add all of them:
60 vanilla
18 lemon
72 chocolate
30 strawberry

180 cupcakes

mary bought five pairs of socks that cost $8 each. if the tax rate was 8% how much did mary pay in total?
(please help!!)
Answer:
The Answer would be $40.64
Step-by-step explanation:
To find a percentage of a certain number, you must multiply that number by the percentage in decimal form. Since the socks cost 8 dollars each 8 x 0.08 = 0.64 Meaning the tax cost is 64 cents. 8 x 5 = 40 Giving us $40.64
