Answer:
(2 2) is answer of this question
$21.00
let the original price = 100%
then the discount price = 100 - 15 = 85%
divide $17.85 by 85 to obtain 1% then multiply by 100 to obtain original price.
original price = $17.85 × 
= $21
Answer:
100 miles
Step-by-step explanation:
Remark
All you need do is start at 4 hours on the y axis and go right until you hit a dot. When you do, go down until you hit a number on the x axis.
It helps if you mark up the graph.
Go right from 4
You hit a dot
Look down.
You should see 100. That's how far you go in 4 hours.
Note
This is an odd graph. Usually time is on the x axis.
Answer: t _(α/2) = 2.060
Step-by-step explanation:
Given that;
sample size n = 26
confidence interval = 95%
level of significance α = ( 1 - 95/100 ) = 0.05
but from the question the salaries (26) are use to estimate the mean of the population so, its a two tail test
therefore our level if significance α will be divided by 2 = 0.05/2 = 0.025
now our degree of freedom df = 26 - 1 = 25
FROM standard t-table value
the critical value of t for the level of significance 0.025
and 25 degree of freedom is 2.060
therefore, t _(α/2) = 2.060
Answer:
A
Step-by-step explanation:
Given
(3x² - 11x - 4) - (2x² - x - 6)
Distribute both parenthesis, noting the second is distributed by - 1
= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms
= x² - 10x + 2 ← this is a quadratic with 3 terms, thus trinomial → A
