Answer:
the truck will over load with 13 refrigerators and 8 pianos
Step-by-step explanation:
13 refrigerators is 2600 lbs
8 pianos is 4200 lbs
both added together is 6800 lbs
the truck can only hold 5900 so 13 refrigerators and 8 pianos is too heavy
Using the normal distribution, it is found that she scores less than 128 in 28.1% of her games.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean 
and standard deviation 
is given by:
- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
In this problem, the mean and the standard deviation are given, respectively, by 
.
The proportion of games in which she scores less than 128 is the <u>p-value of Z when X = 128</u>, hence:
Z = -0.58
Z = -0.58 has a p-value of 0.281.
She scores less than 128 in 28.1% of her games.

Answer:
paid 8 bucks an hour 69 thousand 14 years
Explanation:
Each equation asks for x . So let's solve it in a way so that at the end remains x = ,then the rest equation.
So first one,
1. a(x+b)=c
ax + ab = c
ax = c - ab
x = (c - ab ) / a
Now we can write that in two ways:
i. We already got the answer for the 2nd blank which is c - ab / a
ii. If we rearrange it so that there is a minus sign, it would be like: c/a - b
Try solving the rest 3 by your self to make sure you understood them. Then scroll down to match the answers.
2. 8(x + a) = b
8x + 8a = b
8x = b - 8a
x = (b-8a)/ 8
First blank for 2nd equation: x = b/8 - a
Second blank: x = b - 8a / 8
3. a(x - 9) = b
ax - 9a = b
ax = b + 9a
x = (b + 9a) / a
First blank for 3rd equation: x = b/a + 9
Second blank: x = b+9a / a
4. c(2 + x ) = 7
2c + cx = 7
cx = 7 - 2c
x = (7 - 2c) / c
First blank for 4th equation: x = 7/c - 2
Second blank: x = 7 - 2c / c
Do let me know if it's correct! <3
