A straight line also measures 180 degrees.

If a straight line is 180 degrees, than 148 degrees plus angle ACB must equal 180 degrees because together they make a straight line.

180 = 148 + ACB
ACB = 32 degrees

Answer:

Step-by-step explanation:

The ray created by line BC has two 180° sides. Side AC intersects this ray and forms two angles. We can find this second angle by subtracting 148 from 180 to get 32.

Answer:

4800 cubic Inches

Step-by-step explanation:

Wesley's laundry basket has a rectangular base with an area of 200 square inches. The basket has a height of 24 inches and it is full of clothes. What is the volume of Wesley's laundry basket?

The volume of Wesley's Rectangular laundry basket = Area of the Base × Height of the basket

Base area = 200 square inches

Height of the basket = 24 inches

Volume of the basket = 200 square inches × 24 inches

= 4800 cubic Inches

Given:

Investment (P) = $10000

Rate of interest (R) = 3.5%

Time (T) = 7 years

To find:

Amount in the account after 7 years

Solution:

Simple interest formula:

$$I=\frac{PRT}{100}$

$$I=\frac{10000\times3.5\times7}{100}$

$I= 2450$

Simple interest = $2450

Amount = Investment + Interest

= 10000 + 2450

= 12450

Therefore $12,450 will be in the account after 7 years.

tom has 6 quarters and 12 dimes in his pocket how many coins does he need to take out his pocket to make sure he has 4 quarters

Alex777 [14]

He would have to take out at least 16 coins.

Taking any less could result in having fewer quarters since even 15 could result in 12 dimes and 3 quarters. This way it will always be at least 4 quarters.

Airida [17]

Answer:

$ME=\frac{Upper-Lower}{2}= \frac{8.15-6.55}{2}= 0.80$

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X$ represent the sample mean for the sample

$\mu$ population mean (variable of interest)

s represent the sample standard deviation

n represent the sample size

Solution to the problem

The confidence interval for the mean is given by the following formula:

$\bar X \pm t_{\alpha/2}\frac{s}{\sqrt{n}}$ (1)

For this case the confidence interval is given by (6.55,8.15). And we can estimate the margin of error with this formula since the confidence interval is symmetrical:

$ME=\frac{Upper-Lower}{2}= \frac{8.15-6.55}{2}= 0.80$
