Answer 1

Answer: hmmm anyhow.. how are you meant to get it? by means of a trigonometric identity? or by something else?

notice the picture

Sorry for all the math questions but I do not understand this at all. someone explain and write the equation for me please?? they are the exact words... doesn't make sense to me:the sum of three times a number (z) and 15 is equal to 21.

Answers

3Z + 15 = 21 equation

1. solution
3Z + 15 = 21
3Z = 21 - 15
3Z = 6 [:3
Z = 2

2 solution
3Z + 15 = 21 [:3
Z + 5 = 7
Z = 7 - 5 = 2

Dion is performing a hypothesis test in which the population mean is 92 and the standard deviation is 2. His sample size is 7 with a mean of 93.5. Which of the following correctly depicts the z-statistic for this data?0.28
0.36
1.98
2.63

Answers

Answer:

Option 3rd is correct

1.98

Step-by-step explanation:

Using the formula:

$z = (X-\mu)/((\sigma)/(√(n)))$

where,

X is the sample mean, $\mu$ is the mean, $\sigma$ is the standard deviation and n is the sample size.

As per the statement:

Dion is performing a hypothesis test in which the population mean is 92 and the standard deviation is 2. His sample size is 7 with a mean of 93.5

⇒X = 93.5, n = 2 , $\mu = 92$ and $\sigma = 2$

Substitute these given values to calculate z;

$z = (93.5-92)/((2)/(√(7))) = (1.5)/(0.755928946) = 1.98431348$

Therefore, the z-statistic for the given data is, 1.98

A worker is paid $9.80 per hour, with time and a half for any hours over 40 per week. If he works 44 hours in a week, what will be his gross pay amount?a. $440.80
b. $450.80
c. $392.00
d. $406.70

Answers

b. 450.80

you multiply 40 x 9.80 ...equals 392.

take 1/2 of 9.80...that equals 4.90.
4.90 plus 9.80 equals $14.70 x 4 = 58.80

$58.80 plus 392. equals $450.80

Find the product. 3(x + 4) (x - 5) A. 3x2 ? 20x B. 3x2 ? 11x ? 20 C. 3x2 ? 3x ? 60 D. 3x2 ? x ? 20

Answers

For this case we must find the product of the following expression: $3 (x + 4) (x-5)$

We must apply distributive property to the terms of the first parenthesis:

$(3x + 12) (x-5) =$

Again we apply the distributive property:

$3x ^ 2-15x + 12x-60 =\n3x ^ 2-3x-60$

ANswer:

$3x ^ 2-3x-60$

Step 1: Distribute the 3 to x and 4

(3x + 12)(x - 5)

Step 2: FOIL (First, Outside, Inside, Last)

Multiply the first of the values in the parentheses together

(3x + 12) (x - 5)

$3x^(2)$

Multiply the outside values in the parentheses together

(3x + 12)(x - 5)

-15x

Multiply the inside values of the parentheses together

(3x + 12)(x - 5)

12x

Multiply the last values of the parentheses together

(3x + 12)(x - 5)

-60

Step 3: Add all the FOIL values together

3 $x^(2)$ + (-15x) + 12x + (-60)

Step 4: Combine like terms

3 $x^(2)$ + (-15x) + 12x + (-60)

3 $x^(2)$ - 3x - 60

Hope this helped!

Given : Karen and Daryl work for a delivery service.Karen made 15 more deliveries than Daryl. Let d be the deliveries made by Daryl .We need to find the expression that represents the number of deliveries Karen made

Karen made 15 more deliveries than Daryl. The mathematical symbol for more than is addition or + sign .

15 more than d can be represented by 15+d.

Option B. 15 + d is the right answer.

The answer is B 15+d
