Answer:
Step-by-step explanation:
X+Y = 13
$18 + $22 = $258
OR
18X+22Y=258
18X + 22(13 - X) = 258
18X + 286 - 22X = 258
286 - 4X = 258
-4X= 258 - 286
-4X = -28
X= 7
Y=6
7 of the X tour packages & 6 of the Y tour packages
Answer: -3
X = -3

Answer:
Step-by-step explanation:
Assumed the base is the longer side.
<u>The height of the parallelogram is:</u>
- h/500 = sin 33°
- h = 500 sin 33°
- h = 272.3 ft
<u>The area is:</u>
- A = bh
- A = 790*272.3 = 215117 ft²
Using the normal distribution, we got that expression for the z-score of her test score is
<h3>What is Normal
Probability Distribution?</h3>
it's a type of probability distribution which is symmetric about the mean, it gives data near the mean are more frequent than data far from the mean.
Given that mean =
and standard deviation =
X=73
we know that formula of z-score is
Hence Z-score can be calculated as
Using the normal distribution, we got that expression for the z-score of her test score is
