Using the formula y=mx+b we know that m=slope and b= y-intercept. So what your just doing is plugging in. So it would be Y= -3/2x-4 . I hope that helps! ^^
Answer:
1.0000
Step-by-step explanation:
Given that a door delivery florist wishes to estimate the proportion of people in his city that will purchase his flowers.
True proportion = 0.05
sample size n = 355
Sample proportion mean= 0.05
Sample proportion std error =
Probability that the sample proportion will differ from the population proportion by more than 0.03
=
i.e. almost certain
3/5 * 9 1/2
1st way. Distributive property of multiplication.
3/5 * 9 = 3*9 / 5*1 = 27/5
3/5 * 1/2 = 3*1 / 5*2 = 3/10
Add the products:
27/5 + 3/10 = (27/5 * 2/2) + 3/10 = 54/10 + 3/10 = 57/10
Simplify: 57/10 into a mixed fraction 5 7/10
2nd way:
Converting the mixed fraction into an improper fraction and multiply.
9 1/2 = ((9*2)+1)/ 2 = 19/2
3/5 x 19/2 = 3*19 / 5*2 = 57/10
57/10 = 5 7/10
3rd way: We can use rounding of fractions to estimate the products.
3/5 * 9 1/2
9 1/2 can be rounded off to 10.
3/5 * 10 = 3*10 / 5
30 / 5 = 6 is the estimated product of rounding.
Solution for 25.5 is what percent of 85
100%/x%=85/25.5
(100/x)*x=(85/25.5)*x - we multiply both sides of the equation by x
100=3.33333333333*x - we divide both sides of the equation by (3.33333333333) to get x
100/3.33333333333=x
30=x
x=30
now we have:
25.5 is 30% of 85
Answer:
16.5
Step-by-step explanation:
Look at the relation between the 2 sides that you have measurements for. One is 16cm, the other 24cm. This means that triangle 2 is 1.5 times larger than triangle 1. Multiply the known measurement from tringle 1, 11cm by 1.5 and you get 16.5 cm
