This question is really confusing me, it talks about unknown angle problems with Algebra.

Sever21 [200]

Answer:

Step-by-step explanation:

The two given and marked angles add up to 90.

A = x

B = 3x + 10

A + B = 90 Substitute for A and B. A and B are just letters I gave things.

x + 3x + 10 = 90 Combine the left

4x + 10 = 90 Subtract 10 from both sides.

4x +10-10 = 90-10 Combine

4x = 80 Divide by 4

4x/4=80/4

x = 20

suppose Richard walks one kilometer every 10 minutes how many meters are there can you walk in an hour at this new rate

Ipatiy [6.2K]

One kilometer is 1000 meters. One hour is 60 minutes, or six segments of 10 minutes each. If you can walk 1000 meters in 10 minutes, you can walk 6000 in an hour (that is REALLY fast, by the way)

SAT scores (out of 1600) are distributed normally with a mean of 1100 and a standard deviation of 200. Suppose a school council

fgiga [73]

Answer:

0.91517

Step-by-step explanation:

Given that SAT scores (out of 1600) are distributed normally with a mean of 1100 and a standard deviation of 200. Suppose a school council awards a certificate of excellence to all students who score at least 1350 on the SAT, and suppose we pick one of the recognized students at random.

Let A - the event passing in SAT with atleast 1500

B - getting award i.e getting atleast 1350

Required probability = P(B/A)

= P(X>1500)/P(X>1350)

X is N (1100, 200)

Corresponding Z score = $\frac{x-1100}{200}$

$P(X>1500)/P(X>1350)\\= \frac{P(Z>2)}{P(Z>1.25} \\=\frac{0.89435}{0.97725} \\=0.91517$
