Answer:

b

Step-by-step explanation:

Answer:

B. $2.14

Step-by-step explanation:

Given that

The price of the five supermarkets would be $1.92, $2.01,

$1.89, $2.22, and $2.16

And, each supermarket would be increased by $0.10

So, the today mean price would be

= ($1.92 + $2.01 + $1.89 + $2.22 + $2.16 + $0.10 × 5) ÷ (5)

= $10.7 ÷ 5

= $2.14

Therefore the second option is correct

250*200=50000cm

2. Volume of a cube: length^3

i 650^3=274625000cm

ii 650 cm=6.5m; 6.5^3=274.625m

Find the expected value of a random variable x having the following probability distribution.

x (-5,-1,0,1,5,8)

Probability (.12, .16, .28, .22, .12, .1)

Answer:

0.86

Step-by-step explanation:

The expected value E(X) is calculated as :

E(X) = Σ(x * p(x))

(-5)(0.12) + (-1)(0.16) + (0)(0.28) + 1(0.22) + 5(0.12) + 8(0.10)

-0.6 + -0.16 + 0 + 0.22 + 0.6 + 0.8

= 0.86

Answer:

you dont divide it.

Step-by-step explanation:

x+8/2 can mean a few things cause its not very clear.

x+ 8/2

x+8/2 (x+8 over 2)

8/2=4 so if its x + 8/2 thats just x+4

Answer:

1 1/2

Step-by-step explanation:

Hi there,

First convert your fractions to mixed numbers:

27/4 and 9/2

Then multiply

(remember to flip second fraction over)

27/4 x 2/9

You would get 54/36,

Now simplify 54/36

Answer:

45

Step-by-step explanation:

Because its supplementary

Answer:

Angle 2: 45

Angle 3: 45

Angle 4: 135

Angle 5: 135

Angle 6: 45

Angle 7: 45

Angle 8: 135

Step-by-step explanation:

Angle 1 and 2 are supplementary meaning the angles add to 180 degrees.

    180-135=45

4 is opposite of 1, so it is the same value (it is also supplementary to angle 2)

3 is opposite 2 and supplementary to 1, so it is 45 as well.

5 is the same as 1 because it is made from the same line crossing a parallel line to the one angle 1 is formed from (sorry that sounds confusing)

6,7,8 are found the same way as 2,3,4, and 5.

Answer:

100degrees

Step-by-step explanation:

From the given diagram;

<2 = <6 (corresponding angle)

Since <6 + 80 = 180

<6 = 180 - 80

<6 = 100 degrees

Since <2 = <6, hence <2 = 100degrees

a) Each jigsaw puzzle costs $1.5.

b) Each paddle ball paddle costs $1.

Given that Do-Nothing #1 paid $8 for 2 paddle ball paddles and 4 jigsaw puzzles.

Do-Nothing #2 paid $18 for 3 paddle ball paddles and 10 jigsaw puzzles.

We need to find how much each cost.

Let's solve the problem step by step.

Let's assume the cost of each jigsaw puzzle is 'x' dollars, and the cost of each paddle ball paddle is 'y' dollars.

According to the given information:

The first person paid $8 for 2 paddle ball paddles and 4 jigsaw puzzles. So, we can write the equation as:

2y + 4x = 8............. eq(i)

The second person paid $18 for 3 paddle ball paddles and 10 jigsaw puzzles. So, we can write the equation as:

3y + 10x = 18............. eq(ii)

Now, we can solve these two equations to find the values of 'x' and 'y'.

To do so, we can multiply Equation 1 by 3 and Equation 2 by 2 to eliminate the 'y' term:

6y + 12x = 24............. eq(iii)

6y + 20x = 36............. eq(iv)

Subtracting Equation 3 from Equation 4, we get:

6y + 20x - (6y + 12x) = 36 - 24

6y + 20x - 6y - 12x = 12

8x = 12

x = 12/8

x = 1.5

Now, substitute the value of 'x' back into Equation 1 to find 'y':

2y + 4(1.5) = 8

2y + 6 = 8

2y = 8 - 6

2y = 2

y = 2/2

y = 1

So, the cost of each jigsaw puzzle is $1.5, and the cost of each paddle ball paddle is $1.

Answer: FAT SONIC SAYS.... THE ANSWER IS 125

Answer:

The value of the test statistic is [tex]t = -1.01[/tex]

The pvalue of the test is of 0.1617 > 0.025, which means that there is no evidence at the 0.025 level that the technique reduces the training time.

Step-by-step explanation:

Using traditional methods it takes 11.4 hours to receive a basic flying license.  Is there evidence at the 0.025 level that the technique reduces the training time?

This means that at the null hypothesis, we test that the mean is of 11.4 hours, that is:

[tex]H_0: \mu = 11.4[/tex]

At the alternate hypothesis, we test that the mean is less than this, that is:

[tex]H_a: \mu < 11.4[/tex]

The test statistic is:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]s[/tex] is the standard deviation and n is the size of the sample.

11.4 is tested at the null hypothesis:

This means that [tex]\mu = 11.4[/tex]

A researcher used the technique on 23 students and observed that they had a mean of 11.0 hours with a variance of 3.61.

This means that [tex]n = 23, X = 11, s = \sqrt{3.61} = 1.9[/tex]

Value of the test-statistic:

[tex]t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}[/tex]

[tex]t = \frac{11 - 11.4}{\frac{1.9}{\sqrt{23}}}[/tex]

[tex]t = -1.01[/tex]

Pvalue of the test and decision:

The pvalue of the test is the probability of finding a sample mean of 11 hours or less, which is the pvalue of t = -1.01 with 23 - 1 = 22 degrees of freedom.

Using a calculator, this pvalue is of 0.1617.

The pvalue of the test is of 0.1617 > 0.025, which means that there is no evidence at the 0.025 level that the technique reduces the training time.

Answer:

12.56m²

Step-by-step explanation:

So the formula for the circumference of a circle is π x diameter, so we just have to plug into our equation (we're using 3.14 as π):

3.14 x 4 = 12.56

So the circumference of your circle is 12.56 meters²
