What is 15% of 140

Mariulka [41]

15% of 40

Of = Multiplication

15% Multiply by 40

Set up a equation

15/100= x/140

Cross Multiply

15* 140= 100*x

2100= 100x

Divide both sides by 100x

2100/100x= 100x/100x

X= 21

You wish to compare the prices of apartments in two neighboring towns. You take a simple random sample of 12 apartments in town

Rom4ik [11]

Answer:

The value of P-value is 0.0472.

Step-by-step explanation:

We are given that you take a simple random sample of 12 apartments in town A and calculate the average price of these apartments. You repeat this for 15 apartments in town B.

Let $\mu_1$ = true average price of apartments in town A

$\mu_2$ = true average price of apartments in town B

So, Null Hypothesis, $H_0$ : $\mu_1=\mu_2$

Alternate Hypothesis, $H_A$ : $\mu_1\neq \mu_2$

The test statistics that have been used here is two-sample t-test statistics, i.e;

The test statistics given to us is 2.1

Now, the P-value of the test statistics is given by the following formula;

P-value = P( $t__n__1+_n_2-_2$ > 2.1)

= P( $t_2_5$ > 2.1) = 0.0236

In two-tailed test, P-value is calculated as = 2 $\times$ 0.0236 = 0.0472

Hence, the value of the p-value is 0.0472.

How did the graph of f(x) = x^2 and g(x) = 3/4 x^2 relate?

nirvana33 [79]

g(x) = $\frac{3}{4} f(x)$ or g(x) is 3/4 times of f(x) , F(x) and g(x) have common solution or intersecting point in the graph parabola at x=0 i.e. in origin and x = $\frac {4}{3}$ .

Step-by-step explanation:

We have a function f(x) = $x^{2}$ and another function , g(x) = $\frac{3}{4} x^{2}$ . In the graph of y = $x^{2}$ , the point (0, 0) is called the vertex. The vertex is the minimum point in a parabola that opens upward. In a parabola that opens downward, the vertex is the maximum point.

Graphing y = (x - h)2 + k , where h = 0 & k = 0

Function g(x) can be formed with compression in function f(x) by a factor of 3/4 , i.e. g(x) = $\frac{3}{4} f(x)$ or g(x) is 3/4 times of f(x).Domain and range of f(x) and g(x) are same ! Although structure of both functions is same the only difference is g(x) is compressed vertically by a factor 3/4. Both are graph of a parabola with vertex at (0,0). Also, F(x) and g(x) have common solution or intersecting point at x=0 i.e. in origin.

Find the selling price cost to the store: $50 markup:10%

Goryan [66]

Answer:

$55

Step-by-step explanation:

I am not good at explaining, but, 10% of 50 is 5.

Marking up means the price goes up.

So if 10% of 50 is 5.

50 + 5 = new price

50 with a mark up of 10% = 55
