1, 4, 6 and 7. Mononomials are equations that only have one kind of number or value. Take number 2 for example. If you see b as a banana, and the number 2 as an apple, you can’t add the two together because they just don’t fit as equals. The answer to that equation gives you another polynomial (3b+2). Number 1 on the other hand, they’re both apples. Therefore you can add them together and get a sum of 2 apples (another mononomial)

A rectangle is 3 times as long as it is wide. the perimeter is 16 feet. find the dimensions

astraxan [27]

Answer:

Width = 2 feet

Length = 6 feet

Explanation:

Variables:

Perimeter = p

Length = l

Width = w

Equation:

2w + 2l = p

It is given that:

l = 3w

and

p = 16 feet

With this information, we can rewrite the equation (substitute)

2w + 2(3w) = 16

Simplify

2w + 6w = 16

Add

8w = 16

Divide both sides of the equation by 8

Width = 2 feet

Length = 3(w) = 3(2) = 6 feet

Hope this helps :)

Answer:

A) p(male)=20/30=2/3

b) p(female) = 10/30=1/3

c) p(11th grade) = 12/30=2/5

d) p(12th grade) = 18/30 = 3/5

e) p( girl and in 11th grade) =4/30=2/15

F) p(12 th grade and female) = 6/30 = 1/5

g) p(male and in 12th grade) = 12/30 = 2/5

h) p(male and if we know the student is female) = 0 if we know the student is male then she can't be male again. these are mutuallyinclusive event and they can't occur at once.FOR more details and solutions,clarification and more explanation contact me via my g mail at [email protected] and I will keep in touch....please leave your comment in thisg mail which is my tutor g mail account please.

A random sample of a specific brand of snack bar is tested for calorie count, with the following results: Assume the population

LenKa [72]

Answer:

The 95% confidence interval for the population mean (calorie count of the snacks bars) is (130.32, 161.68).

Step-by-step explanation:

The question is incomplete:

"A random sample of a specific brand of snack bar is tested for calorie count, with the following results: 149, 145,140,160,149,153,131,134,153. Assume the population standard deviation is σ=24 and that the population is approximately normal. Construct a 95% confidence interval for the calorie count of the snack bars."

We start by calculating the mean of the sample:

$M=\dfrac{1}{9}\sum_{i=1}^{9}(149+145+140+160+149+153+131+134+153)\\\\\\ M=\dfrac{1314}{9}=146$
