For synthetic division:
1) Write the coefficients of the polynomial under the division symbol, in order. Make sure you include coefficients that are 0, so they may not be written out in the polynomial!
The coefficients are 7, 1, 0 (the coefficient of x), and -4 in that order
2) The divisor is in the form of x - a. The number "a" goes outside the bracket.
a = 5
Since 7, 1, 0, -4 are under the bracket and 5 is outside the bracket, the answer is C.

Answer: C
Answer:
From (0,0) and (2,3) the slope is 2/3.
Step-by-step explanation:
The cost will be <u>$20.40</u>
<h3>
EXPLANATION</h3>
10% of $28 = $2.80
10% x 2 = $5.60 = 20%
$5.60 + $2 = $7.60
$28 - $7.60 = <u>$20.40</u>
Hope this helps!
Answer:
Step-by-step explanation:
Given that Home sales has 95% confidence interval to estimate the average loss in home value.
a) If std deviation of losses doubles as 3000 from 1500, we have margin of error also increases. Because margin of error
= ±Critical value * Std error
= ±Critical value * Std dev/sqrt n
Hence we find that whenever std deviation increases the margin of error increases, for the same level of confidence.
b) Whenever confidence level increases, critical value increases and as a result margin of error increases. Hence by reducing from 95% to 90% confidence interval would be reduced. True
c) Instead of changing conf level, increasing sample size would give more reliale and accurate results.
Answer x = 8
Solving steps
80° +(7x-1)° +(6x-3)° =180°
x = 8
