3.5/8=0.4375
when you round if last number is higher than 5 then you chose higher number, if it's lower, you chose lower. If it's 5, you look if next number is pair (chose higher) or nonpair (chose lower).
so you round to 0.437
and then 0.44
and then 0.4
1.0 gallon = 16 cups
0.5 gallon = 8 cups
1 week = 7 days
( 0.5 × 7 ) = 3.5gallon
(0.5 × 7) × 16
This is the expression used to show
Answer:
$47,000
Step-by-step explanation:
Let u represent the unknown amount of budget
10/100× u = $5000
10u/100=$5000
Cross multiply both sides
10u= $500000
Divide both sides by the coefficient of u
10u/10=$500000/10
u= $50000
Therefore, this year's budget is $50000
Since Smith's budget this year is $3000 greater than last year's budget, to find last year's budget we simply subtract the difference from this year's budget.
$50000- $3000
= $47000
Thus, Smith's total budget for last year was $47000.
Answer: <u>56.9</u> years to <u>63.1</u> years.
Step-by-step explanation:
Confidence interval for population mean (when population standard deviation is unknown):
, where = sample mean, n= sample size, s= sample standard deviation, = Two tailed t-value for .
Given: n= 24
degree of freedom = n- 1= 23
= 60 years
s= 7.4 years
Two tailed t-critical value for significance level of and degree of freedom 23:
A 95% confidence interval on the true mean age:
Hence, a 95% confidence interval on the true mean age. : <u>56.9</u> years to <u>63.1</u> years.
We'd need a value, a coefficient, that effectively tosses away the variable "y" and leaves "x" all by her lonesome.
and our sharpest value for that, is our very good friend Mr Zero, c = 0, cy = 0y = 0.
