The diameter of a circle that has an area of 452.16 mm

1 answer:

3 0

The diameter is 24 since if you ÷ it by 2 you get 12 to get area it is radius squared so 12 × 12= 144×pi which is 3.14= 452.16 mm you can even check in a calculator

Heights (cm) and weights (kg) are measured for 100 randomly selected adult males, and range from heights of 139 to 192 cm and

Bumek [7]

Answer:

The weight of an adult male who is 158 cm tall is 59.32 kg.

Step-by-step explanation:

The regression equation representing the relationship between height and weight of a person is:

$\hat y=-105+1.04 x$

Here,

y = weight of a person (in kg)

x = height of a person (in cm)

The information provided is:

$\bar x=167.77\ \text{cm}\\\bar y=81.54\ \text{cm}\\r(X, Y)=0.201\\p-value=0.045$

The significance level of the test is, α = 0.01.

The hypothesis to test the significance of the correlation between height and weight is:

H₀: There is no relationship between the height and weight, i.e. ρ = 0.

Hₐ: There is a relationship between the height and weight, i.e. ρ ≠ 0.

Decision rule:

If the p-value of the test is less than the significance level, then the null hypothesis will be rejected and vice-versa.

According to information provided:

p-value = 0.045 > 0.01

The null hypothesis will not be rejected at 1% level of significance.

Thus, concluding that there is no relationship between the height and weight.

Compute the weight of an adult male with height, x = 158 cm as follows:

$\hat y=-105+1.04 x$

$=-105+(1.04\times 158)\\=-105+164.32\\=59.32$

Thus, the weight of an adult male who is 158 cm tall is 59.32 kg.

If length and width of a rectangle are in the ratio 4 to 5 and the perimeter of the rectangle is 144, find the dimensions of the

Zinaida [17]

Answer:

So dimension of rectangle are :

Length = 32

Width = 40

Step-by-step explanation:

Let the length of rectangle be 4x and width of rectangle be 5x.

Remember ratio of length and width is 4 to 5.

Perimeter of rectangle is given as 144.

i.e 2 (length +width) = 144

or 2 ( 4x + 5x ) = 144

Solving this for x, we get :

or 9x = 144/2

or 9x = 72

or x = 72/9

or x = 8

So dimension of rectangle are :

Length = 4 x = 4*8 = 32

Width = 5x = 5*8 = 40

8 335 40 8 * 40 = 320 335 - 320 15

8 15 1 8 * 1 = 8 15 - 8 7

8 70 0.8 8 * 8 = 64 70 - 64 6

8 60 0.07 8 * 7 = 56 60 - 56 4

8 40 0.005 8 * 5 = 40 40 - 40 0

The quotient is then added as

40 + 1 + 0.8 + 0.07 + 0.005 = 41.875
