nika2105 [10]

Answer:

A. 48 Km.

B. 62.5 miles.

Step-by-step explanation:

From the diagram given above, the following data were obtained:

50 miles = 80 Km

A. Converting 30 miles to kilometres.

50 miles = 80 Km

Therefore,

30 miles = 30 miles × 80 Km / 50 miles

30 miles = 48 Km

Thus, 30 miles is equivalent to 48 Km.

B. Converting 100 km to miles.

80 Km = 50 miles

Therefore,

100 Km = 100 Km × 50 miles / 80 Km

100 Km = 62.5 miles

Thus, 100 Km is equivalent to 62.5 miles.

Find the difference of the following polynomials: (-2r4 + 3r3 - 10) and (4r4 - p3 + 2r2 + 7).

Vilka [71]

$-6 r^{4}+4 r^{3}-2 r^{2}-17$ is the difference between $-2 r^{4}+3 r^{3}-20 \text { and } 4 r^{4}-p^{3}+2 r^{2}+7$

Step-by-step explanation:

Given equations,

$-2 r^{4}+3 r^{3}-20 \text { and } 4 r^{4}-p^{3}+2 r^{2}+7$

Difference of the polynomial is written as

$=-2 r^{4}+3 r^{3}-20-\left(4 r^{4}-p^{3}+2 r^{2}+7\right)$

Open the brackets and multiply with -1 the whole expression $\left(4 r^{4}-p^{3}+2 r^{2}+7\right)$ becomes

$=-2 r^{4}+3 r^{3}-20-4 r^{4}+p^{3}-2 r^{2}-7$

$=-6 r^{4}+4 r^{3}-2 r^{2}-17$

This is the difference of given two polynomials is $-6 r^{4}+4 r^{3}-2 r^{2}-17$ .

Answer:

Step-by-step explanation:

Degrees of freedom is the number of values in the final calculation of a statistic that are free to vary. Degrees of freedom are related to sample size and calculated by n-1 where n is the sample size.

The Supervisor selects 10 teddy bears as sample from 5000 teddy bears produced daily. Therefore in this situation, there are 10-1=9 degrees of freedom
