How to find the area of a triangle with a base of 32ft

Sergeu [11.5K]

Well to find the area of any figure you must first have knowledge on the formula. The formula for a triangle is 1/2 x b x h. Since you have the base 32, multiply that by 1/2 which will give you 16. Then you have to multiply 16 by the height. I'm not sure what the height is because you never gave me one but hopefully this helped! God bless :)

Mr. and Mrs. Lopez are putting square tiles on the floor in their bathroom.They can fit 6 rows of 4 tiles in the bathroom.How ma

Trava [24]

They can fit 24 tiles because

6 rows times 4 tiles =24 tiles

6x 4 =24

Find how much it will cost.

24 x 5 = 120

It will cost $120

Solve for x someone please help me out

____ [38]

Answer:

Since there are no terms that can be combined I assume that you would simply subtract y from either side so X +Y = R would turn into X = Y - R. Then you would have done all that you can to solve for X

Which of the following is the solution to the compound inequality below

Vaselesa [24]

So starting with the first inequality:

Firstly, subtract 1/5 on each side. $\frac{3}{2}x \geq -\frac{6}{5}$

Next, multiply each side by 2/3, and your answer should be:

$x \geq -\frac{12}{15}\\\\ x \geq-\frac{4}{5}$

Second inequality:

Firstly, add 7/3 on each side $-\frac{1}{2} x\geq \frac{22}{3}$

Next, multiply by -2 on each side, and flip the less than or equal to sign because you are multiplying by a negative. Your answer will be $x\leq -\frac{44}{3}$

In short, the correct option is the first option.

The proportion of BYU-Idaho students that are married is p = .25. You plan to take a random sample of 100 students and calculate

Rama09 [41]

Answer:

$p \sim N (p, \sqrt{\frac{p(1-p)}{n}})$

And the parameters are given by:

The mean is given by:

$\mu_p = 0.25$

The standard deviation is:

$\sigma_{p} =\sqrt{\frac{0.25(1-0.25)}{100}}= 0.0433$

And the distribution would be bell shaped and normal

Step-by-step explanation:

For this case we have the following info given :

p =0.25 represent the proportion of BYU-Idaho students that are married

n = 100 represent the sample size

And for this case we can check the conditions in order to use the normal distribution:

1) np = 100*0.25 = 25>10

2) n(1-p) =100*(1-0.25)= 75>10[/tex]

3) Independence is assumed in each sample and the probability is the same

So then we have all the conditions satisfied, and the distribution for the proportion would be given by:

$p \sim N (p, \sqrt{\frac{p(1-p)}{n}})$

And the parameters are given by:

The mean is given by:

$\mu_p = 0.25$

The standard deviation is:

$\sigma_{p} =\sqrt{\frac{0.25(1-0.25)}{100}}= 0.0433$

And the distribution would be bell shaped and normal
