Answer:
$112.80
Step-by-step explanation:
If he earns $0.235 per pack, and there are 480 packs, then our equation is:
0.235 x 480 = $112.80
Pretty sure x is 4 in #9
FG is congruent to ED, and GD and FE are parallel, so that means
16x + 1 = 65
Subtract 1 on both sides you get
16x = 64
Divide by 16 on both sides
x = 4
Answer:
0
Step-by-step explanation:
Let X to be a random variable that looks a binomial distribution which denoted the number of employees out of the 281 who earn the prevailing minimum wage or less
The sample size n = 281
The population parameter p = 5% = 0.05
Using normal approximation for the mean.



The standard deviation is:





By using continuity correction; the sample mean x is:
x = 30 - 0.5
x = 29.5
The z statistic test can now be as follows:



Z = 4.23
Thus, the probability that company A will get a discount is
P(X ≥ 30) = P(Z >4.23)
= 1 - P(Z < 4.23)
By using the Excel function for the z score 4.23 i.e. "=1 - NORMSDIST(4.23)" we get;
= 0.0000
Let the positive number be

The expression is

⇒ expanding the bracket gives,

⇒ rearranging to equate one side to zero

⇒ Dividing each term by 7 to simplify

⇒ Factorising gives


and

Hence, the first number is -5 and the second number is 3
Answer:
B x<-8
Step-by-step explanation:
-2x -3> 13
-2x > 13+3
-2x >16
since you will divide both side by a negative number, the operator will change from > to <
-2x /-2 < 16/-2
x<-8
