Answer:

28 slices

Step-by-step explanation:

Take the length of the roll and divide by the size of the slice

10 1/2 ÷ 3/8

Change the mixed number to an improper fraction

(10*2 +1) /2 ÷ 3/8

21/2 ÷ 3/8

Copy dot flip

21/2 * 8/3

Rewriting

21/3 * 8/2

7 * 4

28

You will get 28 slices

Answer:

13

Step-by-step explanation:

radius is half of the diameter so is the radius is 6.5cm then the diameter is 13  problem solved....

Answer:

13 cm

Step-by-step explanation:

Radius is half a circle & if

Radius times two that would equals diameter

6.5(2) = 13

Step-by-step explanation:

Yes, they are similar because if you convert both of the measurements to fractions, which will be 2/3 and 8/12, you can see that if you simplify 8/12, you will get 2/3. That is why they are similar.

Answer:

0.82cm

Step-by-step explanation:

Answer:

r = 0.81 cm

Step-by-step explanation:

Volume of a cylinder = πxr²xh

Volume = 48cm³

Height = 9 inches = 22.86 cm

Radius = ?

Using the above formula:

V = πr²h

r² = V / (πh)

r² =  48 / (π(22.86))

r² = 48/71.81

r² = 0.67 cm

Taking square root on both sides

r = 0.81 cm Ans

Answer:

A

Step-by-step explanation:

F test is a statistical method used to determine which models best fits the population from which the sample is derived. It is a ratio of two variances. Variance measure the rate of dispersion

The formula for calculating f-test = explained variance / unexplained variance

There are two hypothesis in an f test :

1. the  null hypothesis  - all slope coefficient are equal to zero

the alternative hypothesis : at least one of the slope coefficient is not equal to zero

Answer:

Step-by-step explanation:

A(0,0), B(2,0), C(3,-3)

Perpendicular bisector of AB: x=1

Perpendicular bisector of AC: y=x-3

Center of circle = intersection of perpendicular bisectors = (1,-2)

Radius = √5

(x-1)² + (y+2)² = 5

Answer:

17.67 mpg

Step-by-step explanation:

The fuel efficiency is given by :

[tex]\eta=1.437+0.541\times s[/tex]

We need to find the fuel efficiency for a speed of 30 mph

Put the value of s equals 30 mph in the above equation.

[tex]\eta=1.437+0.541\times 30\\\\\eta=17.67\ mpg[/tex]

So, the required fuel efficiency is equal to 17.67 mpg.

Answer:

15 feet

Step-by-step explanation:

if the dog run is a rectangles then the formula for the perimeter is 2h+2l

if we plug in the numbers we know we get this:

2h+2(5)=40

2h+10=40

2h=30

h=15

Answer:

x = 24

Step-by-step explanation:

a^2 + b^2 = c^2

7^2 + b^2 = 25^2

49 + b^2 = 625

-49              -49

b^2 = 576

square root them

b = 24, or x = 24

Hope this helped! Have a nice day! Plz mark as brainliest!!!

Answer:

17.91÷5=3.582

then

3.582×9=32.238

or 32.2 or just 32

Step-by-step explanation:

when you see something like this all you have to do is divide the two number then with that number just multiply.

Answer:

800

Step-by-step explanation:

I rounded 39 to 40 and 24 to 20 to get numbers that are eadult multiplied

then we can do 40*20 which is 800 using mental math

hope this helps <3

Answer:

1000

Step-by-step explanation:

4*2 = 8

40 * 20 = 800

4*5 = 20

40* 5 = 200

40 * 20 + 40 * 5 = 800 + 200 = 1000

40 * 25 = 1000

Answer:

The Z score for $37,000 is 8.49.

Step-by-step explanation:

To solve this question, we need to understand the normal probability distribution and the central limit theorem.

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

Mean family income is $34,000, with a standard deviation (for the population) of $5,000.

This means that [tex]\mu = 34000, \sigma = 5000[/tex]

Subsample of 200 city residents.

This means that [tex]n = 200, s = \frac{5000}{\sqrt{200}} = 353.55[/tex]

What is the Z score for $37,000 ?

This is Z when X = 37000. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

By the Central Limit Theorem

[tex]Z = \frac{X - \mu}{s}[/tex]

[tex]Z = \frac{37000 - 34000}{353.55}[/tex]

[tex]Z = 8.49[/tex]

The Z score for $37,000 is 8.49.

Answer:

There are 160 cats at the store.

Step-by-step explanation:

There are 40 black cats, which is 25% of all the cats. You are trying to find all the cats at the store, or 100% of the cats at the store. So:

40 = 25%

40(4) = 25% (4)

160 = 100%

There are 160 cats at the store.

Answer:

160

Step-by-step explanation:

25%=1/4=0.25

=40×4

=160
