Jacob went bowling over the weekend. On Saturday, he bowled at Bowlero, where he
rented shoes for $3.25 and paid $3.75 for each game. On Sunday, he bowled at the
Cowtown Bowling Center, where he rented shoes for $2.50 and paid $4.00 per game. If
he spent the same amount each day, how many games did he bowl? (Let the number of
games played = x.)
Answer:
x= 3
Step-by-step explanation:
Blowlero's cost of shoes + the cost of one game = $7.00. If we add the cost of a game two more times, we get $14.50
At Cowtown Bowling Center, we can do the same thing. The cost of shoes + the cost of a game= $6.50. If we add the cost of a game two more times, we get $14.50.
For Jacob to have spent the same amount each day, he would have had to played three games at both places.
Answer:
x = 3

Step-by-step explanation:
is y = -2x + 7 a relation or function
Answer:
It is a relation and a function.
Step-by-step explanation:
The domain of y = -2x + 7 is the set of all real numbers (assumed to be).
For each x real, the equation y = -2x + 7, means that exactly one real number is associated with x. Thus, it is a function. We note that a function is a special type of relation.
Note that a change can be an increase or a decrease.
For an increase, use a positive number.
For a decrease, use a negative number.
(b)Deon removed 72 fish from his pond over a period of 9 days. He removed the same number of fish each day. What was the change in the number of fish in the pond each day?
Answer:
72 fish = 9 days * x fish, x fish/day = 72 fish / 9 days = 8 fish/day

The results of a national survey showed that on average, adults sleep 7.3 hours per night. Suppose that the standard deviation is 1.2 hours and that the number of hours of sleep follows a bell-shaped distribution. If needed, round your answers to two decimal digits. If your answer is negative use “minus sign”.
(a) Use the empirical rule to calculate the percentage of individuals who sleep between 4.9 and 9.7 hours per day.
Enter your answer as a percentage.
%
(b) What is the z-value for an adult who sleeps 8 hours per night?
(c) What is the z-value for an adult who sleeps 6 hours per night?
Using the Empirical Rule and z-scores, we have that:
a) 95% of individuals who sleep between 4.9 and 9.7 hours per day.
b) Z = 0.58.
c) Z = -1.08.
What does the Empirical Rule state?It states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.In item 2, both 4.9 and 9.7 are 2.4 hours from the mean, that is, 2 standard deviations, hence 95% of individuals who sleep between 4.9 and 9.7 hours per day.
What is the z-score formula?The z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
For this problem, the mean and the standard deviation are given as follows:
[tex]\mu = 7.3, \sigma = 1.2[/tex]
The z-score for an adult who sleeps 8 hours per night is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (8 - 7.3)/1.2
Z = 0.58.
The z-score for an adult who sleeps 6 hours per night is:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (6 - 7.3)/1.2
Z = -1.08.

5. Victoria sells different sizes of homemade candles.
• Small candles cost the least and sell for $5 each.
• Extra-large candles cost the most and sell for $20 each,
Yesterday Victoria sold a total of 4 candles, including 1 small candle and 1 extra-large candle.
Which could be the total amount Victoria earned from selling candles yesterday?
A. $20
B. $25
C. $50
D. $85
Answer:
Hello! Your answer is C. $50!
Step-by-step explanation:
The problem says Victoria sold a TOTAL of 4 candles. 2 of them are given. If you add up a small and XL candle, its 25. So, you have to try to add 25 and a combinations of small and/or XL candles. When you add one small and one XL, you get 50. Since $50 is the only amount listed that is correct, it would be your answer. Hope this helps!
Answer:
i think 25 because
Step-by-step explanation: 4 x 5= 20 and 4 x 20= 80 so 80+ 20 = 100 then 100 divided by 4= 25

An IQ test is designed so that the mean is 100 and the standard deviation is 10 for the population of normal adults. Find the sample size necessary to estimate the mean IQ score of statistics students such that it can be said with 99% confidence that the sample mean is within 8 IQ points of the true mean. Assume that σ=10and determine the required sample size using technology. Then determine if this is a reasonable sample size for a real world calculation. The required sample size is
Answer:
sample size = 10
it is not practical because we can't draw a conclusion for a complete population based on the sample size of 10 people
Step-by-step explanation:
mean = 100
standard deviation = sigma = 10
confidence level = 99%
The z-score for 99% confidence level = z = 2.58
mean IQ is within 8 IQ points so:
error = E = 8
sample size = n (we don't know it)
Since the distribution is normal, we can use the formula of margin of error for z-distribution to calculate the missing sample size:
[tex]E = z * \frac{sigma}{\sqrt{n} } \\\sqrt{n} = z * \frac{sigma}{E} \\\\\sqrt{n} = 2.58*\frac{10}{8} \\\\\sqrt{n} = \frac{25.8}{8} \\\\n = (\frac{25.8}{8} )^{2}\\n = 10.4\\[/tex]

let f(x)=2x^2+7x-5 and g(x)=-8^2-3x+5 what is g(x)+f(x)
Answer:
2x^2 + 4x - 64
Step-by-step explanation:
it is telling us to add the functions together so we use this equation:
2x^2 + 7x - 5 + (-8^2) - 3x + 5
after combining like terms we get
2x^2 + 4x -8^2
and then lastly we square the -8 and get
2x^2 + 4x - 64

A firm’s production function is
Q = 50L − 0.01L2
where L denotes the size of the workforce. Find the value of MPL in the case when
(a) L = 1 (b) L = 10 (c) L = 100 (d) L = 1000
The value of MPL for the various cases are;
A) MPL = 49.98
B) MPL = 49.8
C) MPL = 48
D) MPL = 30
We are given;
Q = 50L - 0.01L²
Now MPL means marginal product of labor and it is defined as the derivative of Q with respect to L. Thus;
MPL = dQ/dL = 50 - 2(0.01L)
A) When L = 1;
MPL = 50 - 2(0.01 × 1)
MPL = 49.98
B) When L = 10;
MPL = 50 - 2(0.01 × 10)
MPL = 49.8
C) When L = 100
MPL = 50 - 2(0.01 × 100)
MPL = 48
D) When L = 1000
MPL = 50 - 2(0.01 × 1000)
MPL = 30

Area = pi*r^2 = pi*36 = 113.1 (rounded to the nearest tenth)
Answer:
113.1 m²

Diameter = 12m
Radius = Diameter/2 = 12/2 = 6
