Answer:

QR = 30

Step-by-step explanation:

GHI ~ PQR means that PQR is the same shape and length ratios as GHI but is a different size.

All of the leg lengths of GHI are multiplied by something to get the leg lengths of PQR.

You're given the leg lengths 12 and 20. So you need to find out what 12 is multiplied by to get to 20. 12 * 5/3 = 20.

So multiply 5/3 by the other leg length 18.

18 * 5/3 = 30

So QR = 30

svp [43]

Answer:

d. H0: μ <= 21.80 Ha: μ > 21.80

Step-by-step explanation:

We set the null hypothesis as what is already given . We are already informed that the average wage is equal to  μ <= 21.80 against the claim that is required. It is required to test whether the average wage of the computer programmers is greater than μ > 21.80

So option d is the best answer.

Hypotheses testing is done  using an observation and a claim. The observation is set as a null hypothesis and claim is set as an alternative hypothesis. The null and alternative hypotheses must be chosen wisely to get the correct results.

The critical region is dependent on the claim set.

raj has $10. if he buys 8 pears and 5 mangoes, he will be short of $1.10. if he buys 5 pears and 4 mangoes , he will receive $1.
Paladinen [302]

Answer:

1 pear = $0.45

1 mango = 1.5

Step-by-step explanation:

8 pears + 5 mangoes = $11.10 ➡ 8p + 5m = 11.10

5 pears + 4 mangoes = $8.25 ➡ 5p + 4m = 8.25

multiply first equation by -4 and second one by 5

-4 ×(8p+5m) = 11.10 ➡ -32p - 20m = 44.4

5 ×(5p+4m) = 8.25 ➡ 25p + 20m = 41.25

add both equations up

-32p - 20m + 25p + 20m = 44.4 + 41.25

-7p = 3.15 ➡ p = $0.45

use this value to find the price of mango

5×0.45 + 4×m = 8.25 ➡ 2.25 + 4m = 8.25 ➡ 4m = 6 ➡ m = $1.5
