Answer:
Step-by-step explanation:
1: You will pay $682.5 for a item with original price of $1050 when discounted 35%. In this example, if you buy an item at $1050 with 35% discount, you will pay 1050 - 367.5 = 682.5 dollars.
2: You will pay $617.5 for a item with original price of $650 when discounted 5%. In this example, if you buy an item at $650 with 5% discount, you will pay 650 - 32.5 = 617.5 dollars.
Answer:
$1484
Step-by-step explanation:
84 / 0.06 = $1400
$1400 + 84 = $1484
Answer:
10
3.4641
2.8965
12.8965
Step-by-step explanation:
Given: 10, 8, 12, 15, 13, 11, 6, 5
c = 95%
a. The point estimate of the population mean is the sample mean. The mean is the sum of all values divided by the number of values:
x = 10 + 8 + 12 + 15 + 13 + 11 + 6 + 5 /8
= 80/8
= 10
b. The point estimate of the population standard deviation is the sample standard deviation. The variance is the sum of squared deviations from the mean divided by n - 1. The standard deviation is the square root of the variance:
s = /(10 – 10)^2 +.... + (5– 10)^2/8 – 1
s = 3.4641
c. Determine the t-value by looking in the row starting with degrees of freedom df = n-1 = 8 –1 = 7 and in the column with = (1 – c)/2 = 0.025 in table :
t_/2 = 2.365
The margin of error is then:
E = t_/2 * s/√n
= 2.365 x s 3.4641/ √8
= 2.8965
d. The confidence intent)] then becomes:
7.1035 = 10 – 2.8965 = x – E <u />
Answer:
the slope will be m=-4
Step-by-step explanation:
<span>Substitute the value of y which is 125,000 in the equation x - 62,500 = 0.25y. The product of 0.25 and 125,000 is 31,250. Transpose 62,500 to the other side of the equation. Add 62,500 to 31,250. The number of votes Maya received which x represent is 93570,</span>
