The average of their maximum speeds was 260 km/h. If doubled Malcolm’s maximum speed would be 80 km/h more than Ravi’s maximum s
san4es73 [151]

Answer:

Malcolm’s maximum speed is 200 km/h and and Ravi’s maximum speeds is 320 km/h.

Step-by-step explanation:

Let x and y are the maximum speeds ( in  km / h ) of Malcolm and Ravi respectively,

Then according to the question,

\frac{x+y}{2}=260

\implies x + y = 520-----(1)

Again according to the question,

2x = y + 80

\implies 2x - y = 80----(2)

Equation (1) + equation (2),

3x = 600

⇒ x = \frac{600}{3} = 200,

From equation (1),

200 + y = 520

⇒ y = 520 - 200 = 320

Hence,  Malcolm’s and Ravi’s maximum speeds are 200 km/h and 320 km/h respectively.

Please someone help!<br> Find ∛-27
Westkost [7]

Answer:

∛-27 or -3

Step-by-step explanation:

I don't think you can do anything further to this problem unless we have to solve for something.

If it is 3 square root of the whole thing, then the answer is -3 because

-3 x -3 x -3 = -27

-3 x -3 = negative x negative = positive = 9

9 x -3 = positive  x negative = negative = -27

Hope this helps!

The amount of time the husband and the wife spend on house work is measured for 15 women and their 15 husbands. For the wives th
dolphi86 [110]

Answer:

The value of the test statistic is z = -0.877.

Step-by-step explanation:

Testing the difference in mean time spent on housework between husbands and wives.

At the null hypothesis, we test if there is no difference, that is, the subtraction of the means is 0:

H_0: \mu_H - \mu_W = 0

At the alternate hypothesis, we test if there is a difference, that is, the subtraction of the means is different from 0.

H_1: \mu_H - \mu_W \neq 0

The test statistic is:

z = \frac{X - \mu}{s}

In which X is the sample mean, \mu is the value tested at the null hypothesis, and s is the standard error.

0 is tested at the null hypothesis:

This means that \mu = 0

For the wives the mean was 7 hours/week and for the husbands the mean was 4.5 hours/week. The standard deviation of the differences in time spent on house work was 2.85.

This means that X = 4.5 - 7 = -2.5, s = 2.85

What is the value of the test statistic for testing the difference in mean time spent on housework between husbands and wives?

z = \frac{X - \mu}{s}

z = \frac{-2.5 - 0}{2.85}

z = -0.877

The value of the test statistic is z = -0.877.
