The sum of two polynomials is 8d5 – 3c3d2 + 5c2d3 – 4cd4 + 9. If one addend is 2d5 – c3d2 + 8cd4 + 1, what is the other addend?

lidiya [134]

This one is a bit confusing but I'll try to answer. Since the sum is given and one of the addend is given, we need to perform subtraction to get the other addend.

8d⁵ - 3c³d² + 5c²d³ - 4cd⁴ + 9 ⇒ SUM
<u>- 2d⁵ - c³d² + 8cd⁴ + 1 </u> ⇒ 1ST ADDEND
6d⁵ - 2c³d² + 5c²d³ -12cd⁴ - 8 ⇒ 2ND ADDEND

Twelve athletes are running a race. A gold medal is to be given to the winner, a silver medal is to be given to the second-place

kykrilka [37]

Answer:

1320

Step-by-step explanation:

We are given that

Total number of athelets are running in race=12

Total number of medals =3

We have to find the total possible number of ways can the 3 medals be distributed.

Total number of ways for choosen gold medal=12

Number of ways for choosen silver medal=11

Number of ways for choosen Bronze medal=10

Total number of possible ways= $12\times 11\times 10=1320$

Hence, total number of possible ways in which 3 medals be distributed=1320

So I was wondering if any of y'all could help me with this:

notsponge [240]

Step-by-step explanation:

1. volume of a cylinder = pi x radius squared x height (I wasn't sure which was the radius/diameter)

2. 615.74

3. 1km

4. rearrange formula for volume of the cylinder to get the radius on 1 side. divide both sides by height and pi to leave u with r². then divide by the square root.

formula= r=square root of 3080³/3.14 × 20

5. height = volume/ pi x radius squared

6. 2463.01

7. 28.01

8. 145.955 m

9. 21.01

10. 17

n = 23 H0: σ2 ≥ 66 s2 = 60 Ha: σ2 < 66 The test statistic has a value of _____. a. 24.20 b. 24.00 c. 20.91 d. 20.00

Arada [10]

Answer:

$\chi^2 =\frac{23-1}{66} 60 =20.00$

d.20.00

Step-by-step explanation:

Notation and previous concepts

A chi-square test is "used to test if the variance of a population is equal to a specified value. This test can be either a two-sided test or a one-sided test. The two-sided version tests against the alternative that the true variance is either less than or greater than the specified value"

$n=23$ represent the sample size

$\alpha$ represent the confidence level

$s^2 =60$ represent the sample variance obtained

$\sigma^2_0 =66$ represent the value that we want to test

Null and alternative hypothesis

On this case we want to check if the population variance is less than 66, so the system of hypothesis would be:

Null Hypothesis: $\sigma^2 \geq 66$

Alternative hypothesis: $\sigma^2$

Calculate the statistic

For this test we can use the following statistic:

$\chi^2 =\frac{n-1}{\sigma^2_0} s^2$

And this statistic is distributed chi square with n-1 degrees of freedom. We have eveything to replace.

$\chi^2 =\frac{23-1}{66} 60 =20.00$

Calculate the p value

In order to calculate the p value we need to have in count the degrees of freedom , on this case 23-1=22. And since is a left tailed test the p value would be given by:

$p_v =P(\chi^2$

The best option is:

d. 20.00
