Answer:

10 ; 22

Step-by-step explanation:

Ghana = G

Cameroon = C

Cameron only = 8

Ghana only = 12

Total sampled = 40

Both Ghana and Cameroon = x

Not traveled to either = 10

Ghana only + Cameroon only + both Ghana and Cameroon + not traveled to either  = total sampled

12 + 8 + x + 10 = 40

30 + x = 40

x = 40 - 30

x = 10

Number that had gone to Ghana before :

Ghana only + both

12 + x

12 + 10

= 22

Answer:$1312.5

Step-by-step explanation:

1500x1.875=2812.5

2812.5-1500=1312.5

Let's simplify this problem using the distributive property.

The first thing we want to do is change the minus to plus a negative.

Now distribute or multiply the 8 times

each of the terms inside the set of parentheses.

So we get 8(5) + 8(-2x) and this simplifies to 40 + -16x.

Answer:

729

Step-by-step explanation:

9x9x9

Answer:

9*9*9 = 729

Step-by-step explanation:

This can also be expressed by 9^3 (Nine cubed)

9 times 9 is equal to 81. 81 times 9 is equal to 729

Answer:

The first box will have 90 marbles, the second 180 and the third 270.

Step-by-step explanation:

Division in a ratio of 1:2:3

1 + 2 + 3 = 6

So

The first box will have 1/6 of the marbles.

The second box will have 2/6 = 1/3 of the marbles

The third box will have 3/6 = 1/2 of the marbles.

First box:

One sixth, so:

(1/6)*540 = 540/6 = 90

Second box:

One third, so:

(1/3)*540 = 540/3 = 180

Third box:

One half, so:

(1/2)*540 = 540/2 = 270

The first box will have 90 marbles, the second 180 and the third 270.

option B

Step-by-step explanation:

ecf-zutd-cpt.

The probability that the dice faces add up to either 4 or 6 is 0.222.

Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event.

Here, After two six sided dice are rolled,

Total outcomes = 36

Probability of getting sum 4 = 3/36     {(1, 3), (2, 2), (3, 1)}

Probability of getting sum 6 = 5/36

Total Probability of getting sum either 4 or 6 = 3/ 36 + 5/36

                                                                          = 8/36

                                                                          = 2/9

                                                                          = 0.222

Thus, the probability that the dice faces add up to either 4 or 6 is 0.222.

Answer:

x = 5 and y = -6

Step-by-step explanation:

The given equations are :

6x + 3y = 12 ...(1)

4x + y = 14 ...(2)

Multiply equation (2) by 3.

12x + 3y = 42 ...(3)

Subtract equation (1) from (3).

12x + 3y-(6x + 3y) = 42-12

12x+3y-6x-3y = 30

6x = 30

x = 5

Put th value of x in equation (2).

4(5) + y = 14

20 +y = 14

y = -6

So, the solution of the equations are x = 5 and y = -6.

Answer:

a) The probability that a single randomly selected value is greater than 27.6

P( X≥27.6) = 0.8051

b) The probability that a  sample of size randomly selected value is greater mean greater than 27.6

P( X≥27.6) = 0.9998

Step-by-step explanation:

Step(i):-

Given that the mean of the Population = 30 weeks

The Standard deviation of the Population = 2.8 weeks

Let 'X' be a Normal distribution

[tex]Z = \frac{x-mean}{S.D} = \frac{27.6-30}{2.8} = -0.857[/tex]

The probability that a single randomly selected value is greater than 27.6

P( X≥27.6) = P(Z≥-0.857)

                 =  0.5 + A(-0.857)

                = 0.5 + A(0.857)

               = 0.5 + 0.3051

               = 0.8051

Step(ii):-

Let 'X' be a Normal distribution

[tex]Z = \frac{x^{-} -mean}{\frac{S.D}{\sqrt{n} } } = \frac{27.6-30}{\frac{2.8}{\sqrt{80} } } = -7.6677[/tex]

The probability that a  sample of size randomly selected value is greater mean greater than 27.6

P( X≥27.6) = P(Z≥-7667)

                 = 0.5 + A(-7.667)

                 =0.5 +0.4998

                 = 0.9998

Answer:

each side of the hexagon measures 40 cm (which agrees with answer B)

Step-by-step explanation:

Recall that a regular hexagon has six equal sides, therefore, each side would be one sixth of the 240 cm:

each side of the hexagon = 240 cm / 6 = 40 cm

Answer:

Diameter = 7

Radius = 3.5

Step-by-step explanation:

Hi! Ace here.

So, the formula to find circumference is dπ or 2rπ

So to find the diameter, you do the circumference/π

To find the radius, you'd do the circumference/2π

Plug-in those numbers and there you go!

Answer:8.3

Step-by-step explanation:trust

Answer:

m<7 = 49°

m<8 = 41°

m<9 = 49°

m<10 = 41°

Step-by-step explanation:

Given :

m<7 ≅ m<9

m<8 = 41°

m<7 = 90° - m<8 (complementary angles)

m<7 = 90° - 41° (substitution)

m<7 = 49°

m<9 = m<7 (m<7 ≅ m<9)

m<9 = 49° (substitution)

m<10 = 90 - m<9

m<10 = 90 - 49

m<10 = 41°
