Suppose that a recent poll found that 50 % of adults in a certain country believe that the overall state of moral values is poor. If a survey of a random sample of 15 adults in this country is conducted in which they are asked to disclose their feelings on the overall state of moral values, complete parts (a) through (e) below.
Answer: 3.75
Step-by-step explanation:
P=0.50, n=15
np= 0.5x15 gives 7.5
n(1-p)= 15x(1-0.5)=7.5
Both are greater than 5
Then Mean, u=np;15x0.5=7.5
Standard deviation, √np(1-p)
15x0.5(0.5)= 3.75
b)simplify the expression
7x2 + 4x – 2 + 8x2 – 9x – 5
Answer:
=25x-7
Step-by-step explanation:
How do you solve this absolute value equation ?
|x + 7| = 3x - 5
Answer:
x=6
Step-by-step explanation:
x+7=3x-5
add 5 to both sides
x+12=3x
subtract x from both sides
12=2x
divide by 2 on both sides
6=x

Samuel drove 28 miles in 32 minutes. Beverly drove 42 miles in 48 minutes.
Are the ratios of miles to minutes for Samuel and Beverly proportional?
Drag and drop to correctly complete the statement.
= Ratio of minutes to miles in which Samuel drove = 28 : 32
= Ratio of minutes to miles in which Beverly drove = 42 : 48
To find whether the time they drove and the distance they covered were proportional or not , let us first change them into a fraction and then simplify them .
= 28 : 32 = 28/32
= 28/32
Both the numerator and the denominator is divisible by 4 .
= 28 ÷ 4 / 32 ÷ 4
= 7/8 = 7 : 8
Samuel = 7 : 8
Beverly = 42 : 48 = 42/48
= 42/48
Both the numerator and the denominator is divisible by 6 .
= 42 ÷ 6 / 48 ÷ 6
= 7/8
Therefore, the ratio of miles to minutes drove by Samuel and Beverly is proportional , 7:8 :: 7:8
Answer:
7:8 7:8
Step-by-step explanation:
if you subtract 28 from 42 and subtract 32 from 48 then you get 14-16. then double it and you get 28-32 then add 14-16 to those again and you get 42-48. because they add up and are equal, take 14-16 and simplify it to 7:8.

Answer:
Vertical stretch of 2
Step-by-step explanation:
Since there is no fraction, it wouldn't be a shrink, and there's a negative symbol therefore it would also be a reflection, and it wouldn't translate down because it's not inside parenthesis or the square root, and it would actually translate up three, therefore it's a vertical stretch of two

Given f(x)=2x+1, find the range value if the domain value is 1.75. *
Answer:
4.5
Step-by-step explanation:
Domain means that value of x and range means the value of f(x) so
[tex]f(x)=2x+1 \\f(1.75)=2(1.75)+1\\f(1.75)=4.5[/tex]
so the range value is 4.5

8x + 4.3= 2(x+6) + 6x - 7.7
Answer:
Step-by-step explanation:
8x=2x+12+6x-7.7-4.3
8x=2x+12+6x-12
8x=8x
x=x
X could be any number
Example : If x=4
4*8+4.3=2(4+6)+6*4-7.7
32+4.3=20+24-7.7
36.3=36.3
