The force vector A has components A sub x =5N, A sub Y = -3N. The force vector B has components B sub x = 5N, B sub y = 4N. What

are the components of the resultant force vector C = A + B?
Question 5 options:

C sub x = 0N, C sub y = -7N

C sub x = 2N, C sub y = 9N

C sub x = 10N, C sub y = 7N

C sub x = 10N, C sub y = 1N

Answer:

C sub x = 10N, C sub y = 1N

Step-by-step explanation:

C=A+B\\\\(C_x,C_y)=(A_x,A_y)+(B_x,B_y)\\\\(C_x,C_y)=(A_x+B_x,A_y+B_y)=(5N+5N,-3N+4N)\\\\(C_x,C_y)=(10N,1N)

A marketing organization claims that more than 10% of its employees are paid minimum wage. If a hypothesis test is performed tha
Genrish500 [490]

Answer:

there is insufficient evidence to support the claim that more than 10% of the employees are paid minimum wage.

Step-by-step explanation:

Given that:

A marketing organization claims that more than 10% of its employees are paid minimum wage.

The null hypothesis is:

H_o : p = 10

The alternative hypothesis is:

H_1 : p > 10

If a hypothesis test is performed that fails to reject the null hypothesis, how would this decision be interpreted

i.e Decision Rule: fails to reject the null hypothesis

Then the interpretation of the decision is that, there is insufficient evidence to support the claim that more than 10% of the employees are paid minimum wage.

Find Angle C. Please I need this rn for homework
ira [324]

Answer: I believe the answer here would be 52.5 degrees.

Step-by-step explanation: Because an isosceles triangle has two equal sides, their base angles would be the same. The angles of a triangle add up to 180 degrees, so you would subtract 75 from 180 and divide 105 by two in order to find one of the base angles.

A cyclist estimates that he will bike 80 miles this week. He actually bikes 75.5 miles. What is the percent error of the cyclist
maw [93]

Answer:

<em>The percent error of the cyclist's estimate is 5.63%</em>

Step-by-step explanation:

<u>Percentages</u>

The cyclist estimates he will bike 80 miles this week, but he really bikes 75.5 miles.

The error of his estimate in miles can be calculated as the difference between his estimate and the real outcome:

Error = 80 miles - 75.5 miles = 4.5 miles

To calculate the error as a percent, we divide that quantity by the original estimate and multiply by 100%:

Error% = 4.5 / 80 * 100 = 5.625%

Rounding to the nearest hundredth:

The percent error of the cyclist's estimate is 5.63%

The ABC Company has a net income of $56,000, assets at the beginning of the year are $263,000 and assets at the end of the year
aleksandr82 [10.1K]

Answer:

19.4 %

Step-by-step explanation:

The formula for<em> return on assets</em> (ROA) is

ROA = Net income /Total assets × 100 %

Since assets vary, we use the <em>average</em> of the total assets over the period.

<em>Calculate the average total assets</em>

At beginning of year, total assets = $263 000

At end of year, total assets            = $313 000

Average = (313 000 + 263 000)/2

Average = 576 000/2

Average = $288 000

===============

<em>Calculate the ROA</em>

Net income = $56 000

ROA = 56 000/288 000 × 100 %

ROA = 0.194 × 100 %

ROA = 19.4 %

The company’s return on assets is 19.4 %.
