Answer:

12.8

Step-by-step explanation:

imagine a right triangle in the middle,

base: 16 ÷ 2 = 8 cm, height: 10 cm, side: s

10² + 8² = s²

=> s = √(10² + 8²)

=> s = √(100 + 64)

=> s = √164

=> s ≈ 12.8

Answer:

[tex] 1,824 \: {in}^{2} [/tex]

Step-by-step explanation:

Area of the figure = Area of rectangle with dimensions 48 in and 32 in + Area of triangle with base 48 in and height 12 in.

[tex] = 48 \times 32 + \frac{1}{2} \times 48 \times 12 \\ \\ = 1,536 + 24 \times 12 \\ \\ = 1,536 + 288 \\ \\ = 1,824 \: {in}^{2} [/tex]

Big brain calculator work

28 + 35 + 42 + 49 + 56 + 63 + 70 = 343

Answer:

343

Step-by-step explanation:

28+35+42+49+56+63+70          We are asked to find the sum, so we add all the numbers in the series.

28+35+42+49+56+63+70 = 343

Answer:

£10.91

Step-by-step explanation:

72p is 1kg of potatoes

1kg of carrots is 62p

10kg of potatoes is £7.20 add 3 extra kg's

which is £2.16

add £2.16 with £7.20 = £9.36

2kg of carrots is £1.24 add an extra half of kg an you get £1.55

Answer:

The p-value of the test is 0.0869.

Step-by-step explanation:

In the 1990s, it was generally believed that genetic abnormalities affected about 5% of a large nation's children.

This means that the null hypothesis is:

[tex]H_{0}: p = 0.05[/tex]

Some people believe that the increase in the number of chemicals in the environment has led to an increase in the incidence of abnormalities.

This means that the alternate hypothesis is:

[tex]H_{a}: p > 0.05[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

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

5% tested at the null hypothesis:

This means that:

[tex]\mu = 0.05, \sigma = \sqrt{0.05*0.95}[/tex]

A recent study examined 384 randomly selected children and found that 25 of them showed signs of a genetic abnormality.

This means that [tex]n = 384, X = \frac{25}{384} = 0.0651[/tex]

Test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.0651 - 0.05}{\frac{\sqrt{0.05*0.95}}{\sqrt{384}}}[/tex]

[tex]z = 1.36[/tex]

p-value:

Testing if the mean is bigger than a value, so the pvalue is the probability of finding a value in the z table higher than 1.36, which is 1 subtracted by the pvalue of z = 1.36.

z = 1.36 has a pvalue of 0.9131

1 - 0.9131 = 0.0869

The p-value of the test is 0.0869.

Answer:

The answer is "64".

Step-by-step explanation:

Let A= look at the number of a card on it {3,5,7,9}

[tex]\to 4 \times 4 = 16 \ odd \ numbers[/tex]

Let B= look at the king of the card = [tex]4 \ Cards[/tex] 

Choose one card A = 16 ways

Choose one card B= 4 ways

selecting one card, either A and B:

[tex]=A \times B \\\\= 16 \times 4 \\\\= 64[/tex]

Answer: See below

Step-by-step explanation:

14) 26/52 of the cards are red, 1/2

15) All of the cards are red or black, 1/1

16) 4/52 of the cards are aces, 1/13

17) 12/52 of the cards are J/Q/K, 3/13

Convert the fractions to whatever unit is needed.

Answer:

Part A: 4x = -5(x-18)

Part B: A and B both = 40 degrees

Step-by-step explanation:

Ok, corresponding angles are in the same position on the two parallel lines cut by the transversal. And they are equal in measure. So, upper right = upper right.

So A = B

4x = -5(x -18)

4x = -5x + 90

9x = 90

x = 10

Angle A = 4x = 40 degrees, which means angle B is also 40, but let's show the work:

Angle B = -5(x - 18) = -50 + 90 = 40

The 4th cone

Step-by-step explanation:

Hello, the answer to your question is the 4th cone; the cone with its bottom half facing skyward.  If you are familiar with plane symmetry, this question is fairly simple.  Since the topmost cone has its bottom half facing downward, it would only be logical to choose the cone that forms mirror halves (superimpose) when paired.  

Hope this helps.

Remark

Area of an entire circle = pi * r^2

Area of a sector = angle / 360 * pi * r^2

Givens

angle = 140

radius = 8

Solution

Area = (140/360) * 3.14 * 8^2

Area =0.3889 * 3.14 * 64

Area = 78.15
