Answers

Answer 1

Answer:

The p-value is less than the alpha (the level of significance) reject the null hypothesis. There is sufficient evidence at the α = 0.1 level of significance to conclude that μ>49.

what is the area of a rectangle that has a height of 7x^2 and a width of 3x^2+8x+7​

Answers

Answer:

21x^4 + 8x + 7

Step-by-step explanation:

This is the answer because:

1) Simplify each term and multiply like terms and multiply them because in order to find the area we have to multiply the height and width.

2) Since we have to multiply like terms, 7x^2 and 3x^2 are the only like terms. Therefore, we multiply 7x^2 * 3x^2 = 21x^4.

3) The rest of the numbers are not like terms.

4) Therefore, the answer is 21x^4 + 8x + 7

f(x) and g(x) were inverse functions, then if f(a) = b, then g(b) = a

f(x) = (5x+1) / x g(x) = x / (5x+1)

f(1) = 6, but g(6) = 6/31 ≠ 1

So, f(x) and g(x) are NOT inverse functions.

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Equality PropertiesSolving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define systems

6x = 10y - 10

x + y + 7 = 0

Step 2: Rewrite systems

6x = 10y - 10

y = -x - 7

Step 3: Solve for x

Substitute:                              6x = 10(-x - 7) - 10Distribute 10:                          6x = -10x - 70 - 10Combine like terms:              6x = -10x - 80Add 10x to both sides:          16x = -80Divide 16 on both sides:        x = -5

Step 4: Solve for y

Define:                                   x + y + 7 = 0Substitute:                             -5 + y + 7 = 0Combine like terms:              y + 2 = 0Subtract 2 on both sides:     y = -2

Before he started washing windows on weekends, Rob had $20. He earned $60 over each of the first three weekends that he spent washing windows. So far, Rob has not spent any of his money.


If n represents a whole number less than or equal to 3, which function shows the total amount of money Rob had after n weekends of washing windows?


answer choices

A. t(n) = 20 + 60n

B. t(n) = 60 + 20n

C. t(n) = 200n

D. t(n) = 200

Answers

Answer:

A. t(n) = 20 + 60n

Step-by-step explanation:

Since Rob already had $20, the equation should have +20 to represent the money he already had.

60n can represent how much money Rob gets after washing windows, since he earned $60 from each weekend he washed windows.

So, A is the correct answer, t(n) = 20 + 60n

OB. y = 3.5 - 4
Oc. y = ks - 4

Answers

Answer:

B. [tex] y = 3x - 4 [/tex]

Step-by-step explanation:

First, using two points (0, -4) and (3, 5), find slope:

[tex]  m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 -(-4)}{3 - 0} = \frac{9}{3} = 3 [/tex]

Slope, m = 3

Next, determine the y-intercept, b.

The y-intercept is the value of y when x = 0. It is the point where the line intercepts the y-axis.

From the graph given, y-intercept, b, is -4.

Substitute b = -4 and m = 3 into [tex] y = mx + b [/tex].

The equation would be:

Find the Length of AC. Round answers to the nearest hundredth (2 decimal places)

Answers

Answer:

32.78

Step-by-step explanation:

Assuming that we have two right triangles joined together, with one having adjacent side a, with a side of 12 ft opposite reference angle 30°, and the other one having adjacent side b, with a side of 12 ft opposite reference angle 45°. Thus, a + b = length of AC.

Let's find a and b.

Finding a:

Reference angle = 30°

Opp = 12 ft

Adj = a

Using trigonometric ratio formula, we have:

tan(30) = 12/a

Multiply both sides by a

a*tan(30) = 12

Divide both sides by tan(30)

a = 12/tan(30)

a = 20.78 (nearest hundredth)

Finding b:

Reference angle = 45°

Opp = 12 ft

Adj = b

Using trigonometric ratio formula, we have:

tan(45) = 12/b

Multiply both sides by a

b*tan(45) = 12

Divide both sides by tan(45)

b = 12/tan(45)

a = 12

Length of AC = 20.78 + 12 = 32.78

A manufacturer of women’s blouses has noticed that 80% of their blouses have no flaws, 15% have one flaw, and 5% have two flaws. If you buy a new blouse from this manufacturer, the expected number of flaws will be:_________

a. 0.15
b. 0.20
c. 0.80
d. 1.00
e. none of the above

Answers

Answer:

b

Step-by-step explanation:

80% +15% +5%=100

15/100= 0.15

5/100= 0.05

therfore

0.15 + 0.05 = number of flaws

=0.20

Based on the flaws that the manufacturer notices, we can infer that the expected number of flaws will be 0.25 which is e. none of the above.

The expected number of flaws is a weighted average of the percentages that have flaws:

=∑ (Percentage of flaws x Number of flaws)

The expected number of flaws is therefore:

= (80% x 0) + (15% x 1) + (5% x 2)

= 15% + 10%

= 0.25

In conclusion, you would expected the number of flaws to be 0.25.
