The quadratic polynomial x^2 +mx+n has roots twice those of x^2 +px+m, and none of m,n, and p is zero. What is the value of n/p?

olga_2 [115]

Answer:

n/p = 8.

Step-by-step explanation:

If the roots of the first equation are A and B we have

A + B = -m and AB = n.

This has roots twice the roots of the second equation so we have:

0.5(A + B) = -p and 0.25AB = m.

So A + B = -2p and AB = 4m

Equating values of A +B and AB:

-m = -2p and n = 4m

m = 2p and m = n/4

2p = n/4

n = 8p

n/p = 8.

Which of the following is not an example of using the distributive property to multiply 12 times 22?

s2008m [1.1K]

That would be : 10(2 * 22)

because 12(20 + 2) = 12 x 22.....and 22(10 + 2) = 22 x 12
whereas, 10(2 * 22) = 10 x 44

MARKING BRAINLIEST TO FIRST CORRECT ANSWER If quadrilateral JKLM had a translation where all the vertices were in the third quad

Likurg_2 [28]

If quadrilateral JKLM were in third quadrant then the coordinates will be (-1,0),(-4,-1),(-4,-2)(-1,-2)

Given Quadrilateral JKLM is in fourth quadrant and coordinates (1,0),(4,-1),(4,-2)(1,-2)

We know that the coordinates of x used to negative in third quadrant and positive in fourth quadrant. Coordinates of y used to negative in third and fourth quadrant.

So in order to change the coordinates from fourth to third we need to change the coordinates of x axis to negative and the coordinates will be :

Coordinates of J will change from (1,0) to (-1,0)

Coordinates of K will change from(4,-1) to (-4,-1)

Coordinates of L will change from (4,-2) to (-4,-2)

Coordinates of M will change from (1,-2) to (-1,-2).

Answer:

1. she subtracted 4 from 20 when she was supposed to add it and get 24

4x-4=20

4x=24

x=6

Step-by-step explanation:

2. x+8_>5

what plus 8 equals a number equal to five

that would be -3

and any number above that since it is saying that the number can be equal to or greater than 5 when it is added together with 8

That the best way I can show my work.

The claim is that the white blood cell counts of adult females are normally? distributed, with a standard deviation equal to 1.6

antiseptic1488 [7]

From the question, we know the population standard deviation, σ = 1.63, the sample standard deviation, s = 3.07, the sample mean, $\bar{x}=7.43$ and the sample size, n = 38.

The question illustrates a hypothesis chi-square test of variance.

The test statistics for a Chi-squared test of variance is given by
$T=(n-1)\left( \frac{s}{\sigma} \right)^2 \\ \\ =(38-1)\left( \frac{3.07}{1.63} \right)^2 \\ \\ =37(1.883)^2=37(3.5473) \\ \\ =131.25$
