An electrician worked 28 hours a week for half a year. If his hourly wage was $25, how much did he earn during this time period?

7 0

So, there are 52 weeks in a year, so divide that in half to get 26 total weeks that he worked. Then, multiply 26 by 28 to get the total amount of hours he worked in his time of working, which is 728 hours. Then, since his hourly wage was $25, multiply 728 by $25 to get a total of $18,200.

Rufina [12.5K]

Answer:

It would cost $232.32, this answer is rounded.

Step-by-step explanation:

The formula for the volume of a square pyramid is:

$V=a^2\frac{h}{3}$

So its just:

$8.8^2\frac{12.5}{3} = 322.67 cm^3$

Then you just multiply the volume by the cost per cubic centimetre:

$322.67cm^3*$0.12=$38.704$

After just multiply the cost of one by how many you want, which is 6:

$38/704*6=232.32$

A large restaurant is being sued for age discrimination because 15% of newly hired candidates are between the ages of 30 years a

Fudgin [204]

Answer:

See explanation below.

Step-by-step explanation:

Let's take P as the proportion of new candidates between 30 years and 50 years

A) The null and alternative hypotheses:

H0 : p = 0.5

H1: p < 0.5

b) Type I error, is an error whereby the null hypothesis, H0 is rejected although it is true. Here, the type I error will be to conclude that there was age discrimination in the hiring process, whereas it was fair and random.

ie, H0: p = 0.5, then H0 is rejected.

You put $1200 in an account that earns 3% simple interest. Y= a (1 + r)t Find the total amount in the account after four years.

olchik [2.2K]

Hello!

To find how much money total will be in the account after four years, you need to use the function, $y = a(1 + r)^{t}$ , as seen above. In this function, a is the starting value, r is the interest rate, and t is the amount of time (in years).

Before substituting values into the function, we need to convert 3% into a decimal. Remember that all percentages are out of 100, so we divide 3 by 100 and remove the percentage sign, or move the decimal two places to the left.

3/100 = 0.03 | 0.03 is the interest rate.

With all the necessary values, we can find the total amount in the account. In this case, a = 1200, r = 0.03, and t = 4.

$y = 1200(1 + 0.03)^{4}$
