Here is your answer:

In order to solve this question you have to multiply the fractions, and remember that a negative times a negative equals a positive.

  • \frac{-6}{7} \times \frac{-9}{5} =
  • \frac{-6}{7} \times \frac{-9}{5} = \frac{54}{35}
  • The numerator and the denominator don't have a common factor therefore cannot be reduced.
  • = \frac{54}{25}
  • You can also switch the improper fraction into a mixed number which would be 1\frac{19}{35}

Therefore your answer will be "54/25 or 1 19/35."

Hope this helps!

6x - 2y = 26<br><br> 2x + 3y = 5<br><br> Solve for X and Y
Softa [21]

Answer:

y is equal to -1

x is equal to 4

Step-by-step explanation:

The first thing you would do is multiply the bottom equation by a negative 3. You will get - 6x - 9y = -15. Keep the top equation the same. Both of the 6x's cancel. You then get -11y = 11 so y is equal to negative 1.

Since you have Y, you can now plug that in to any equation to find the value of x. -6x - 2(-1) = 26. You're left with 4. Plug both of the values into each equation to double check.

The test statistic of z= -2.39 is obtained when testing the claim that p&lt;0.52.
krek1111 [17]

Considering the situation described, we have that:

a) The critical value is of z = -1.645.

b) Since the test statistic is less than the critical value, we should reject the null hypothesis H0.

<h3>What is the critical value?</h3>

We have a left-tailed test, as we are testing if the proportion is less than a value. Hence the critical value is z with a p-value equals to the significance level, hence z with a p-value of 0.05, hence z = -1.645.

<h3>What is the decision?</h3>

Considering the test statistic, for a left-tailed test, we have that:

  • Less than the critical value: Reject H0.
  • Equal or greater: Do not reject.

In this problem, z = -2.39 is less than -1.645, hence we should reject the null hypothesis H0.
