8 cm
O Perimeter - 126 cm, area = 131.25 cm?
O Perimeter = 46 cm, area = 972 cm?
Perimeter = 126 cm, area = 972 cm2
Perimeter - 46 cm, area = 131.25 cm2
Answers
Answer:
Perimeter is 126cm and area is 972[tex]cm^2[/tex]
Step-by-step explanation:
Scale factor means you multiply the dimensions by the factor. In this case 4.5
The width 6cm becomes 27cm. The length 8cm becomes 36cm.
Perimeter = 2*L + 2*W, L is length and W is width.
[tex]P=27*2cm+36*2cm\\P=54cm+72cm\\P=126cm[/tex]
Area = L*W
[tex]A=27cm*36cm\\A=972cm^2[/tex]

c.
lawyer, master’s degree
d.

Answers
Answer:
the correct answer is going to be D
Step-by-step explanation:
Pharmacists, with doctorate degrees, would have the best company pension contribution.
Given that,
There is a positive correlation between the number of years of education and the amount of company pension contributions.
which of the given professions would have the best company pension contributions is to be determined.
The relation is defined as the dependency of one thing over another by any means is called relation.Or in mathematics, the relation of function is defined as for any function in its domain there is an image in range, which is called relation.
Here,
There is only one option that holds the situation of the correlation between the number of years of education and the amount of company pension contributions a pharmacist with a doctorate degree.
Because education in the pharmacy sector is not limited and it will increase exponentially.
Thus, pharmacists, with doctorate degrees, would have the best company pension contribution.

O A. 16
B. 36
O C. 64
O D. 72
Answers
What number must you add to x² + 16x = 3 to complete the square 64: Option C
What is a perfect square?You should be aware that a perfect square is a term that has two common factors
The given equation is x² + 16x = 3
To make the equation a perfect square, Add the square of half of the coefficient of s to both sides
This is to say that (16/2)² = 8² = 64
The equation becomes x²+16x+64 = 3+64
Then you can factorize the equation and simplify the right hand side

Music streaming services are the most popular way to listen to music. Data gathered over the last 12 months show Apple Music was used by an average of 1.73 million households with a sample standard deviation of 0.46 million family units. Over the same 12 months Spotify was used by an average of 2.17 million families with a sample standard deviation of 0.33 million. Assume the population standard deviations are not the same. Using a significance level of 0.01, test the hypothesis of no difference in the mean number of households picking either service.
Answers
Answer:
There is enough statistical evidence to suggest that there is no difference between the mean number of households picking either service
Step-by-step explanation:
The parameters of the music streaming service are;
The average number of households using Apple Music, [tex]\overline {X}_1[/tex] = 1.73 million
The standard deviation, σ₁² = 0.46 million
The average number of households using Spotify, [tex]\overline {X}_2[/tex] = 2.17 million
The standard deviation, σ₂² = 0.33 million
The significance level = 0.01
Hypothesis testing with different population standard deviation
[tex]Z = \dfrac{\overline {X}_1 - \overline {X}_2}{\sqrt{\dfrac{\sigma_1^2}{n_1} +\dfrac{\sigma_2^2}{n_2}} }[/tex]
H₀: [tex]\overline {X}_1[/tex] ≠ [tex]\overline {X}_2[/tex]
H₁: [tex]\overline {X}_1[/tex] = [tex]\overline {X}_2[/tex]
[tex]Z = \dfrac{1.73- 2.17}{\sqrt{\dfrac{0.46^2}{12} +\dfrac{0.33^2}{12}} } = -2.6923[/tex]
p-value for the test statistic = 2 × P(Z <-2.6923) = 2 × 0.00357 = 0.00714
Therefore, the p-value is less than the significance level, and it is therefore unlikely that the result will be observed under the null hypothesis
We therefore reject the null hypothesis and there is enough statistical evidence to suggest that there is no difference between the mean number of households picking either service
George Smith own's George's Joint, a gas station and convenience store. George is trying to get a better understanding of his business and wants to estimate the mean number of gallons of gasoline sold to his customers.

From his records, he randomly selects 60 sales and find the mean number of gallons sold is 8.6. What is the point estimate of the population mean
Answers
Answer:
The point estimate of the population mean is of 8.6 gallons sold.
Step-by-step explanation:
Point estimate for the population mean:
From a large sample, the point estimate for the population mean is the sample mean.
In this question:
The sample mean number of gallons sold is 8.6. This means that the point estimate of the population mean is of 8.6 gallons sold.

At noon, a barista notices that she has $30 in her tip jar. If she makes an average of $0.45
from each customer, how much will she have in her tip jar if she serves n customers during
her shift?
(equation)
How much will she make if she serves 134 customers?
How many customers did she serve by noon?
Answers
Answer:
a [tex]A = 30 + 0.45 n[/tex]
b [tex]A = 90.3[/tex]
c 0 customers
Step-by-step explanation:
Given
[tex]Base\ Amount = 30[/tex]
[tex]Rate = 0.45[/tex] per customer
Solving (a): Amount (A) on n customers
This is calculated as:
[tex]A = Base\ Amount + Rate * n[/tex]
[tex]A = 30 + 0.45 * n[/tex]
[tex]A = 30 + 0.45 n[/tex]
Solving (b): Amount on 134 customers
In this case: n = 134
So:
[tex]A = 30 + 0.45 * 134[/tex]
[tex]A = 30 + 60.3[/tex]
[tex]A = 90.3[/tex]
Solving (c): Customers at noon.
At noon, the amount is 30.
So:
[tex]A = 30 + 0.45 n[/tex]
[tex]30 = 30 + 0.45n[/tex]
Collect like terms
[tex]0.45n = 30 - 30[/tex]
[tex]0.45n =0[/tex]
[tex]n = 0[/tex]
