b) 32 mm

Step-by-step explanation:

a) The legs of the smaller triangle are 6-6-3. The larger triangle is 1/3 larger than the other triangle so the lengths of the legs are 8-8-4 so the perimeter is 20 ft.

b) Since one side of the larger square is 8 mm, this means that the perimeter is 4×8mm = 32 mm.

Which coordinate point represents the y -intercept of the equation 3x + 2y = 18

Answers

Answer:

(-6,18)

Step-by-step explanation:

3x + 2y = 18

2y= -3x + 18

y=-3/2 x + 18

give x=0

y=-3/2 *0+18

y=18#

y=18

3x+2(18)=18

3x+36=18

3x=18-36

3x=-18

x=-18/3

A 30 ft ladder is leaning against a wall making a 48 angle with the ground. Approximately how far from the wall is the base of the ladder?

Answers

The image below shows how the diagram should look. We are solving from how far the wall is from the ladder and we are representing it as x.

Based on the type of triangle below we are going to use Trigonometry ratios.

We are going to use the Sine ratio, which is opposite over hypotenuse.

Let opposite be x, hypotenuse be 30 and theta (angle) be 48 deg.

Sine 48 = x/30

Make x the subject

x = 30 Sine 48

Just go ahead and lunch this in a calculator.

x = 22.3 ft

Therefore the distance of the wall from the base of the ladder is 22.3 ft

WITH SOLUTION PLEASE​

Answers

Hello there I hope you are having an great day :) A chocolate milk container in the form of a rectangular prism is 5 cm long, 3 cm wide, and 9 cm high. How many cubic centimetres of chocolate milk can it hold?

V = L x W x H

Volume = length x Width x Height.

V = (5cm) (3cm (9cm)

V = 135cm^3

Therefore, the chocolate milk container can hold 135 cubic centimetres. Hopefully that helps you :)

Round 27346 to 2 significant figures i need a step by step expansion

Answers

Answer:

27000

Step-by-step explanation:

We want to round 27346 to 2 significant figures.

Now, the number already has 5 significant figures, so to reduce it to 2 sig figures, we will have to reduce the 3 digits from the right to zero so that we can have just 2 significant figures by approximating.

Thus, 3 is less than 5 and so 7 cannot increase. Thus, we will have 27000 as the number when reduced to 2 significant figures.

P(starts with M wins presidency) = required outcome / Total possible outcomes

Number of names which starts with M = 1

Total number of names = 5

P(starts with M wins presidency) = 1/ 5

For vice presidency :

Number of names which starts with M = 0

Total number of names = 4

P(starts with M wins vice presidency) = 0/4

P(name which starts with M wins presidency and vice presidency) = 1/5 * 0/4 = 0

The College Board originally scaled SAT scores so that the scores for each section were approximately normally distributed with a mean of 500 and a standard deviation of 100. Assuming scores follow a bell-shaped distribution, use the empirical rule to find the percentage of students who scored greater than 700.
a. 95%.b. 2.5%.c. 5%.d. 97.5%.

Answers

Using the Empirical Rule, the percentage of students who scored greater than 700 is:

b. 2.5%

What does the Empirical Rule state?

It states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.Approximately 95% of the measures are within 2 standard deviations of  the mean.Approximately 99.7% of the measures are within 3 standard deviations of the mean.

700 is two standard deviations above the mean. 5% of the measures are more than two standard deviations of the mean. Since the normal distribution is symmetric, 2.5% of these measures are below 300 and 2.5% are above 700, hence option B is correct.

Magdeline wants to know if the number of words on a page in her art book is generally more than the number of words on a page in her science book. She takes a random sample of 25 pages in each book and then calculates the mean, median, and mean absolute deviation for the 25 samples of each book.


Book Mean Median Mean Absolute Deviation
Art 68.7 50 15.4
Science 54.2 55 7.9


She claims that because the mean number of words on each page in the art book is greater than the mean number of words on each page in the science book, the art book has more words per page. Based on the data, is this a valid inference?

Answers

Answer:

Yes

Step-by-step explanation:

Because the mean is the total of all the words divided by the number of pages, so if the mean is higher, that means that there are more pages on average in the art book than the science book.

Answer:

no

Explanation:
