Answer:

It should take him <u>1.75 minutes</u> to complete 20 multiplication facts, which is the same thing as 1 minute and 45 seconds, or 105 seconds.

Step-by-step explanation:

a. If it takes him one minute to complete 20 multiplication facts, that's 3 seconds per question, because 60/20 = 3.

b. Multiply 3 x 35 questions to get 105 seconds.

c. Divide 105 seconds by 60 seconds (60 in a minute) to get 1.75 minutes, which is the same thing as 105 seconds.

Hope this helps! Feel free to give me Brainliest if you feel this helped. Have a good day and good luck on your assignment. :)

Suppose the mean height for adult males in the U.S. is about 70 inches and the standard deviation is about 3 inches. Assume men’
nlexa [21]

Question options :

a. They should be between 64 and 76 inches tall.

b. They should be close to the height that is 95% of the mean. That is, 66.5 inches, plus or minus 2 standard deviations.

c. They should be at or below the 95th percentile, which is 74.92 inches.

d. None of the above.

Answer: a. They should be between 64 and 76 inches tall.

Step-by-step explanation:

Given the following :

Assume men's height follow a normal curve ; and :

Mean height = 70 inches

Standard deviation= 3 inches

According to the empirical rule ;

Assuming a normal distribution with x being random variables ;

About 68% of x-values lie between -1 to 1 standard deviation of the mean. With about 95% of the x values lying between - 2 and +2 standard deviation of mean. With 99.7% falling between - 3 to 3 standard deviations from the mean.

Using the empirical rule :

95% will fall between + or - 2 standard deviation of the mean.

Lower limit = - 2(3) = - 6

Upper limit = 2(3) = 6

(-6+mean) and (+6+ mean)

(-6 + 70) and (6+70)

64 and 76

Parallel to y=2÷3x+6<br> Passes through (6,7)
erma4kov [3.2K]

Answer:

Step-by-step explanation:

Parallel to y=2÷3x+6

Passes through (6,7)

slope is (2/3)

Solve for when y is 7 and x is 6.

take out the + 6 at the end because it doesnt change the slope. replace with b. (y=mx+b)

replace y and x.

7 = (2/3)(6)+b

solve for b and then put it back into the equatio and make 6 and 7 into x and y again.

Maggie needs to spend at least six hours each week practicing the piano. She has already practiced three and one fourth hours th
vfiekz [6]

Answer:

three and one fourth + 2x ≥ 6

Step-by-step explanation:

Let

x -----> the minimum number of hours he needs to practice on each of the two days

we know that

needs to spend at least seven hours each week practicing the drums

so

3\frac{1}{4}+2x\geq 6\ hours

Convert mixed number to an improper fraction

3\frac{1}{4}\ hours=\frac{3*4+1}{4}=\frac{13}{4}\ hours

substitute

\frac{13}{4}+2x\geq 6\ hours

Subtract 13/4 both sides

2x\geq 6-\frac{13}{4}

2x\geq \frac{11}{4}

Divide by 2 both sides

x\geq \frac{11}{8}

therefore

The minimum number of hours he needs to practice on each of the two days is \frac{11}{8}\ hours
