there are 9 students that play tennis. if 75% of the students do not play tennis, how many are in the class

Answers

Answer 1

So 9 students = 25% (100%-75%=25%)
100 : 25 = 4
4 * 9 =
36 students

rosa, roberto, andrea, and inno find an estamate for the square root of ten who has proposed the best solution

Rosa, use the square root of 9 and the square root of 25
Roberto, use the square root of 4 and the square root of 90
Andrea, use the square root of 11 and the square root of 12
Inno, use the square root of 9 and the square root of 16

Answers

Inno: use the square root of 9 and the square root of 16 10 is between the perfect squares 3^2 = 9 and 4^2 = 16 Rosa's solution of 9 and 25 uses perfect squares but the wider range leaves more room for error. Roberto's as well with the added problem that 90 is not a perfect square and calculating that square root is just as hard as 10. Andrea's solution requires extrapolation which is best avoided if interpolation is an option and 11 and 12 are not perfect squares.

Final answer:

Inno's solution of using the square root of 9 and 16 is the best estimate for the square root of ten, as it provides a narrower and more accurate range for the estimate.

Explanation:

To estimate a square root that is not a perfect square, one strategy is to find integers that the number falls between, and then those integers' respective square roots give us a range within which the square root of the number will fall.

Rosa and Inno's approaches are similar and most appropriate because they both use 9 and another square number that is close to 10.

Rosa uses the square roots of 9 and 25. Since the square root of 9 is 3, and the square root of 25 is 5, we know that √10 is a little more than 3, because 10 is closer to 9 than it is to 25. Inno uses the square roots of 9 and 16. Since the square root of 16 is 4, √10 is closer to 3 than 4 because 10 is closer to 9.

Therefore, Inno's solution gives a closer estimate of the square root of 10, as it falls between 3 and 4 (and closer to 3), and this is the best solution among those proposed.

Martin had 7 pounds of grapes left, and he gave away 2/5 of them. Explain how to use compatible numbers to estimate the amount of grapes he gave away.

Answers

Answer:

Step-by-step explanation:

The amount of grapes that he gave away is 3.5 pounds.

Number of grapes with Martin = 7 pounds

Fraction given away = 2/5

In this case, to use compatible numbers, we have to find a fraction that's close to 2/5 which will be 1/2.

Then, we have to multiply 1/2 by 7 and this will be:

= 1/2 × 7

= 3.5

In conclusion, the amount of grapes that he gave away is 3.5 pounds.

how is the sentence "9 is less than x is -1" written as an equation
A. 9 - x = -1
B. x - 9 = -1
C. x - 9 = 1
D. x - 1 = 9

Answers

Must not have more than ONE "=" sign in an equation like this one.

9 is less than x is -1

I will take the liberty of deleting the first "is" and then write out the expression:

9 less than x is -1, or x-9 = -1

Add 9 to both sides to determine the value of x: x = 8 (answer)

The sentence "9 is less than x is -1" written as an equation is A. 9 - x = -1

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

Now the given sentence is,

9 is less than x is -1

So, since less than means subtraction

Therefore 9 is less than x is written as,

9 - x

And this equal to -1

So we can write,

9 - x = -1

which the required equation of the given sentence.

The sentence "9 is less than x is -1" written as an equation is 9 - x = -1

Thus the correct answer is A. 9 - x = -1.

"The reading speed of second grade students is approximately normal, with a mean of 88 words per minute (wpm) and a standard deviation of 12 wpm. a) What is the probability a randomly selected student will read more than 95 words per minute?"
95-88 7
Calculate the z-score for 95 wpm: z = --------------- = --------
12 12

This fraction is approx. equal to 0.583.

Look in the body of a table of positive z scores for this 0.583. The table will give you a decimal fraction that represents the area to the LEFT of z=0.583.
Subtract that result from 1.000 to obtain the probability that a student's typing skills will be greater than 95 wpm. If you have a calculator with the normal cumulative density function (normalcdf) built in, find the area under the normal curve to the left of 0.583 and then subtract this result from 1.000.

My calculator result was 1.000-0.720 = 0.280.

This is the answer because it can be found by using data!

Answer:

How many hours do you spend at the pharmacy each month?

Step-by-step explanation:

A statistical question is a question that will have variable answers. It will not have a single answer. Like - How tall are the students in your class?

So, here the answer is -

How many hours do you spend at the pharmacy each month?

As here, the answer can be variable. Some days it can be 8 hours, some days it can be 12 hours.

is 4 3/8 larger than 4.25 lb

Answers

Answer: Yes

Explanation:
4.25
4[tex] \frac{3}{8} [/tex] this can be written as a decimal by dividing 3 by 8
3 ÷ 8 = .375
4.375 > 4.25

4 [tex]\frac{3}{8}[/tex] is larger than 4.25 lb.

We'll convert the fraction 4 [tex]\frac{3}{8}[/tex] to a decimal and compare it to the decimal 4.25.

First,

convert the mixed number 4 [tex]\frac{3}{8}[/tex] to an improper fraction:

4 [tex]\frac{3}{8}[/tex] = 4 + [tex]\frac{3}{8}[/tex]

Next,

convert [tex]\frac{3}{8}[/tex] to a decimal:

3 ÷ 8

= 0.375.

Add the whole number part and the decimal:

4 + 0.375

= 4.375.

Now, we compare 4.375 with 4.25:

4.375 is clearly larger than 4.25.

So, 4 [tex]\frac{3}{8}[/tex] is larger than 4.25 lb.
