Since we have to divide 60 by ¾, so get 60/ ¾ =60* 4/3 = 80
Answer:
$28.35
Step-by-step explanation:
The headphones are $80.99 and are 35% off. To find the amount he will save, change the 35% to a decimal by moving it two times to the left, which is 0.35. Multiply 80.99 and 0.35 to get 28.3465. Round to get $28.35.
Answer:
$2072
Step-by-step explanation:
Note that:
1 year = 12 months
Hence:
1 year = 12 months
3 years = x months
Cross Multiply
x = 3 × 12
x = 36 months
She makes a down payment of $200 and monthly payments of $52 each for three years.
Her total cost is represented by the expression
= $200 + $52 × m
Where m = number of monthly payments.
$200 + $52 × 36
= $200 + $1872
= $ 2072
Let

denote the random variable for the weight of a swan. Then each swan in the sample of 36 selected by the farmer can be assigned a weight denoted by

, each independently and identically distributed with distribution

.
You want to find

Note that the left side is 36 times the average of the weights of the swans in the sample, i.e. the probability above is equivalent to

Recall that if

, then the sampling distribution

with

being the size of the sample.
Transforming to the standard normal distribution, you have

so that in this case,

and the probability is equivalent to

(-2,8) (1,2)
m=2-8/1-(-2)
m=-6/3
m= -2
y=-2x+b
(-2,8)
8=-2(-2)+b
8=-4+b
12=b
b=12
y=-2x+12
Hope this helps!
