Answer:
b) equals 20 hours.
Step-by-step explanation:
The sampling distribution of means refers to the distribution of all the possible sample means, with a certain sample size (in this case, n=100) extracted from the population.
The sampling distribution of the means is equal to the population mean. That does not mean that every sample will result in a mean equal to the population, but that the population of sample means will have an average of 20 hours.
Answer:
2 and 2/3
Step-by-step explanation:
2/3 multiplied by 4
Answer:
Step-by-step explanation:
Number 2 first:
See the graph below for a hint. (Do you know how to use Desmos ?)
factoring seems to make no sense for
but "guess and check" seems to work. I tried 4 for x, but that proved false. 3 for x made sense. You get
so -9 +6 +4 = 1 is true. So (3,1)
x+y=4 becomes 3 + 1 = 4 Also true
According to the graph, (0,4) would also be a solution, so (3,1) and (0,4)
Part 1:
Factor
as
set each equal to 0 and get
x = -3 and x = -1 so the solutions seem be (-3,0) and (-1,0)
y = 2x + 6 factors to 2(x +3)
(-1,0) doesn't work!
But Desmos shows something else as a solution set for both:
(1,8)
y=2x+6 substitute values 8=2(1) +6 8=2+6 True
y =
. Substitute values
8= 1+4+3 True
Answer:
From the perspective of the 32-year-old male, the monetary values corresponding to surviving the year is -$194 and for not surving the year is $109 806.
Step-by-step explanation:
If the 32 year old survives the year it means he has to pay $194 towards the policy denoted by the negative sign. However if he does not survive the year it means he gets the death benefit - cost of the policy that is
$110 000-$194= $109 806.
Answer:
448 in²
Step-by-step explanation:
2 parallelograms = 2x10x14=280
3 triangles = 3x1/2x14x8=168
280+168=448 in²
