How to solve this equation
Set up an equation for each store by multiplying the cost of the basketball by the number of basketballs bought (b) and add the cost of the hoop:
Hoops House: total = 20b + 200
Baller Basement: total = 15b + 250
Now to solve for b, set the two equations equal to each other:
20b + 200 = 15b + 250
Subtract 15b from both sides:
5b + 200 = 250
Subtract 200 from both sides:
5b = 50
Divide both sides by 5:
B = 10
The answer is 10 basketballs
16 > - 8 + x
A. x > 24
B. x < 24
C. x > 8
D. x < 8
Answer:
B. x < 24
Step-by-step explanation:
16 > - 8 + x
+8 > +8 + x Add 8 to both sides
24 > x
Final answer: x < 24
Mary Jane spins the spinner 15 times. The arrow lands 6 times on a star and 9 times on the heart. Which THREE
statements are correct when comparing the experimental and theoretical probabilities?
Answer:
A, E, C
Step-by-step explanation:
The statements are correct when comparing the experimental and theoretical probability that will be A, C, and E.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
In a spinner, there are 3 stars and 1 heart.
Then the theoretical probability of the star is given as,
⇒ 3 / 4
⇒ 0.75
Then the theoretical probability of the heart is given as,
⇒ 1/4
⇒ 0.25
Mary Jane spins the spinner 15 times. The arrow lands 6 times on a star and 9 times on the heart.
The experimental probability of the heart is given as,
⇒ 9 / 15
⇒ 0.60
The experimental probability of the star is given as,
⇒ 6 / 15
⇒ 0.40
The statements are correct when comparing the experimental and theoretical probability that will be A, C, and E.

=========================================================
Explanation:
There are 16 ways to pick the first place winner, 15 for second place, and 14 for third place. Each time we count down by 1 because no single person can be in two (or more) places at once.
Overall, this leads to 16*15*14 = 3360 different permutations

The distance, s(t), in feet traveled by a freely falling object is given by the function s(t) = 162, where
t is time in seconds. Use this formula to find the time it would take for an object to fall to the
ground from a cliff that is 1024 feet high.
7 sec
64 sec
8 sec
9 sec
Answer:
8 seconds
Step-by-step explanation:
The correct formula is
s(t) = 16t²
-------------------------
1024 = 16t²
Divide both sides by 16
64 = t^2
Take the square root of both sides
8 = t

If pp is inversely proportional to the square of qq, and pp is 24 when qq is 2, determine pp when qq is equal to 4.
Answer:
pp = 48
Step-by-step explanation:
If they are proportional, when you multiply qq by 2 you also have to do the same with pp
qq = 2*2 = 4
pp = 24*2 = 48
The value of p when q = 4 is given by the proportion equation p = 6
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion equation be represented as A
Now , the equation is
p ∝ 1/q² be equation (1)
p is inversely proportional to the square of q , so
On simplifying the equation , we get
p = k/q²
where k is the proportionality constant
Multiply by q² on both sides of the equation ,we get
k = pq²
Now , when q = 2 , p = 24
Substitute the value of p and q in the equation , we get
k = 24 x ( 2 )²
k = 24 x 4
k = 96
Now , when q = 4
p = k/q²
Substitute the value of k and q in the equation , we get
p = 96 / ( 4 )²
p = 96/16
p = 6
Therefore , the value of p is 6
Hence , the proportion is p = k/q² and p = 6

Step-by-step explanation:
1. Although a Ferris Wheel is turning at a constant rate, the rate of change of height is
not constant. Explain why.
9514 1404 393
Explanation:
The "speed made good" is the product of the speed and the cosine of the angle between the direction of the speed and the direction of interest. A change in height is accomplished by speed in the vertical direction.
When a spot on the Ferris Wheel is traveling vertically, as at a side position, the angle difference is zero and the cosine is a maximum. All of the vertical speed results in a change in height.
When a spot on the Ferris Wheel is traveling horizontally, as at a top or bottom position, the angle difference from the vertical is 90°, and the cosine of the angle is 0. That is, none of the horizontal speed results in a change in height.
The vertical speed is not constant because the angle of the direction of motion with respect to the vertical is not constant.

Ben plays basketball 6 times every 3 weeks. At this rate how many times does he play basketball in 10 weeks ?
Answer:
20 times
Step-by-step explanation:
Let's assign the variable "w" for weeks
6 = 3w
Divide by 2 on both sides
2 = w
That means he plays basketball 2 times every week
For 10 weeks we multiply each side by 10
2 x 10 = 10 x w
20 = 10w
He plays basketball 20 times in 10 weeks.

The manager of the Danvers-Hilton Resort Hotel stated that the mean guest bill for a weekend is $600 or less. A member of the hotel's accounting staff noticed that the total charges for guest bills have been increasing in recent months. The accountant will use a sample of future weekend guest bills to test the manager's claim. a. Which form of the hypotheses should be used to test the manager's claim? H 0: less than or equal to $600 H a: greater than $600 b. When H 0 cannot be rejected, can we conclude that the manager's claim is wrong? No c. When H 0 can be rejected, can we conclude that the manager's claim is wrong? Yes
Answer:
H0 : μ ≤ 600
H1 : μ > 600
B.) NO
C.) YES
Step-by-step explanation:
Here, the null hypothesis is the claim, that mean guest bill is $600 or less ; The alternative will be the opposite of the null which is the counterclaim. This ubstge accountants assertion that guest bill has been increasing
Hence,
H0 : μ ≤ 600
H1 : μ > 600
When the null cannot be rejected, that means there is no sufficient evidence to support the alternative hypothesis, Hence, we stick with the manager's claim
When H0 can be rejected, then there is sufficient evidence to support, the accountant's claim. Thus, we go with the accountant's claim and conclude that the manager is wrong.
