Answer:

Distance as follows: 1cm = 100,000,000

Mercury  is 58,000,000 = 0.6cm

Venus is 110,000,000 = 1.1cm

Earth is  150,000,000 = 1.5cm

Mars is 230,000,000 = 2.3cm

Jupiter is 780,000,000 = 7.8cm

Saturn is 1,400,000,000 = 14cm

Neptune is  4,500,000,000 = 45cm

Step-by-step explanation:

Answer:

The answer is no because for 1 hour he gets 20 dollars and for 2 hours he gets 30$ (which is less for working 2 hours). So, if you multiply 2 hours with 20 dollars, you should get 40, not 30. So therefore, it is not proportional. And same for 3 hours: multiply 3 with 20 to get 60, not 50.

question one : choice b ( $1.50 )

question two : choice b ( 3 1/2 miles )

question three : about 250 hotdogs

question four : choice d ( $20 per ticket )

Step-by-step explanation:

question two : 1 3/4 - 7/4 - 1/2 X 7 = 3 1/2

question three : 50/12 - about 4.17 - 4.17 X 60 = about 250

question four : 480/24 = 20

Answer:

8800km

Step-by-step explanation:

If 1cm = 400km

then you have to substitute in 22cm instead of 1cm making it..

22x400=8800.

Answer:

A 3/8

Step-by-step explanation:

2 digits with 9 options (as there is no 0).

and no double digits allowed.

that gives us 9 options for the first and then only 8 options for the second digit (as whatever was picked for the first, cannot be picked again for the second position).

in total

9×8 = 72

possible combinations.

and we are looking for the probability that the second digit is a prime number, when the first digit was already a prime number.

P(B|A) = P(B and A)/P(A)

we need prime numbers. what prime numbers are possible ?

2, 3, 5, 7

that means we have 4 desired cases out of 9 for theoretically each position (4/9), but again one less for the second position : 3 out of 8 (3/8).

that gives us as combined probability of A and B

4/9 × 3/8 = 12/72

the probability that the first digit is a prime number is again 4/9.

so, formally, we have for

P(B|A) = 12/72 / 4/9 = 12×9 / 4×72 = 12 / 4×8 =

= 3/8

Answer:

The answer is A, 3/8

Answer: $34.78

Step-by-step explanation:

Answer:

$37.81

Step-by-step explanation:

I set up a true proportion equation.

x/$34.69 = 9/100

If you cross multiply, you'll find the value of x, which is 9%.

34.69 x 9 ÷ 100 = 3.12

$3.12 is 9% of 34.69; add them together to get the total.

$34.69 + $3.12 = $37.81

Answer:

4 4/9

Step-by-step explanation:

First, let's convert these fractions into improper fractions to make adding easier. If we do this, it makes the expression: 5/3 + 25/9.

Since 5/3 has a different denominator from 25/9, we need to make the denominator 9.

3 * 3 = 9. We also have to multiply the numerator. 5 * 3 = 15. So, 5/3 = 15/9.

So, now we have 15/9 + 25/9. We can easily add now!

15/9 + 25/9 = 40/9. Now we have to convert the fraction into a mixed number. 40/9 = 4 4/9.

1 2/3 + 2 7/9 = 4 4/9.

[MA]:

4 \(\frac{4}{9}\)

The explanation:

Rewrite the equation with the parts separated:

= 1 + \(\frac{2}{3}\) + 2 + \(\frac{7}{9}\)

Solve the whole number parts:

1 + 2 = 3

Solving the fraction parts:

\(\frac{2}{3}\) + \(\frac{7}{9}\) = ?

LCD of 2/3  and 7/9. Rewrite to solve

LCD: 9

\(\frac{6}{9}\) + \(\frac{7}{9}\) = \(\frac{13}{9}\)

Combine, then done!

3 + 1 + \(\frac{4}{9}\) = 4\(\frac{4}{9}\)

Have a great day/night.

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Answer: 4th one

Step-by-step explanation:

1. for x-axis flip, x stays same y doesn't

2. for y-axis flip, y stays same x doesn't

Answer: Point B would be (-11, 7) and Point C would be (11,7)

Step-by-step explanation:

Whenever we transfer or flip a point over the x-axis, the x-coordinate will stay the same but the y-coordinate with change signs (positive into negative or vise versa) and if we flip the point over the y-axis, the y-coordinate will stay the same but the x-coordinate with change signs.

Step-by-step explanation:

5x because all we know that they brought 5 dollars of an x number of things

plus 12 because they end up buying DVDs worth 12 bucks

We can conclude that exists 211680 ways.

We know that the three research department is have 8, 10, and 7 members.

We choose a delegate and an alternate to represent the department.

First case: department have 8 members.

So, for a delegate, we have 8 options, and for a alternate 7, so a total of

\(8 \times 7 = 56 \ \text{options}\)

Second case: department have 10 members.

So, for a delegate, we have 10 options, and for a alternate 9, so a total of

\(10\times 9 =90 \ \text{options}\)

Third case: department have 7 members.

So, for a delegate, we have 7 options, and for a alternate 6, so a total of

\(7\times6 = 42 \ \text{options}\)

Therefore, we get:

\(56 \times 90 \times 42 = \bold{211680}\)

Hence, we conclude that exists 211680 ways.
