What is the volume of the following rectangular prism?

Answer:

The approximate percentage of SAT scores that are less than 865 is 16%.

Step-by-step explanation:

The Empirical Rule 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.

In this problem, we have that:

Mean of 1060, standard deviation of 195.

Empirical Rule to estimate the approximate percentage of SAT scores that are less than 865.

865 = 1060 - 195

So 865 is one standard deviation below the mean.

Approximately 68% of the measures are within 1 standard deviation of the mean, so approximately 100 - 68 = 32% are more than 1 standard deviation from the mean. The normal distribution is symmetric, which means that approximately 32/2 = 16% are more than 1 standard deviation below the mean and approximately 16% are more than 1 standard deviation above the mean. So

The approximate percentage of SAT scores that are less than 865 is 16%.

Step-by-step explanation:

70(10/100)=7 broken cookies.

7/70=1/10 is the fraction broken

(70-7)/70=63/70 is the fraction remaining whole

Answer:

(a) 1/7 are broken

(b) 6/7 remain whole

Step-by-step explanation:

70 is a nice number to deal with in terms of percentages and fractions. If 10% of the cookies are broken, do 10/70. That fraction simplified gets you 1/7. To find the remaining whole cookies. Do 7/7 - 1/7 = 6/7 (or if you already know that in your head that works too)

Answer is (4) 4/3

Step-by-step explanation:

[tex]\frac{1- -3}{5-2}[/tex]

[tex]\frac{4}{3}[/tex]

Answer:

slope is 4/3

Step-by-step explanation:

1-(-3)/5-2

4/3

Answer:

Step-by-step explanation:

32 ÷ 4 + ([tex]\frac{1}{2}*16) - 2[/tex] =   8 + (1*8) - 2

                                 = 8 + 8 - 2

                                 = 16 - 2

                                 = 14

Answer:

Point-slope equation for line of slope m that passes through (x₀,y₀):

y-y₀ = m(x-x₀)

In your case, m=5 and (x₀,y₀)=(1,9):

y-9 = 5(x-1)

Answer:

80cm3

Step-by-step explanation:

volume of the composite solid=volume of the

pyramid+

volume of the

cuboid

volume of the pyramid=1/3* base area*height

=1/3*5*4*6

=40cm3

volume of the cuboid=base area *height

=5*4*2

=40cm3

volume of the composite solid=40cm3+40cm3

=80cm3

Answer: See Explanation

Step-by-step explanation:

Simple interest is calculated as:

= principal × rate × time.

The interest for a 2% interest rate loan of $3000 for 1 year will be:

= principal × rate × time.

= $3000 × 2% × 1

= $3000 × 2/100 × 1

= $3000 × 0.02 × 1

= $60

The interest for a 3% interest rate loan of $3500 for 1 year will be:

= principal × rate × time.

= $3500 × 3% × 1

= $3500 × 3/100 × 1

= $3500 × 0.03 × 1

= $105

Answer:

12

Step-by-step explanation:

Answer: 12

Step-by-step explanation:

I don't know if you mean using the Complements Method but I really wouldn't recommend using this method for all problems unless your teacher asked you to specifically.

Here is how to:

1. take the "complement" of the number we are subtracting (The "complement" is the number to add to make 10 (or 100, 1000, etc, depending on how many digits we have)

2. add it to to the number we are subtracting from

3. discard the extra "1" on the left

If you mean to do it mentally, think about it like this:

20 + (-9) = 11 You are essentially adding negative nine to twenty, not subtracting nine. If you want to see this better, try using a number line.  When you add a negative number, you move to the left on the number line.

Same thing with 8 + (-7) = 1

You are adding negative seven to eight.

All that is left to do is adding both of the results together, and you get twelve.

11 + 1 = 12

Answer:
