Hello,
y²+4y+4=7
==>(y+2)²-7=0
==>(y+2-√7)(y+2+√7)=0
==>y=-2+√7 or y=-2-√7
Answer:
x = 14.
Step-by-step explanation:
Knowing (8x+6) is equal to 118.
You need to solve for x.
Subtract 6 from 118 = 112.
112 / 8 = 14.
Therefore x = 14.

Answer:
The standard deviation used in the test statistic is 0.04.
Step-by-step explanation:
A single proportion <em>z</em>-test can be used to determine whether the proportion of people in Norway with a blood type of A positive is different from that in the United States.
The proportion of people in Norway with a blood type of A positive is 36% or 0.36.
The hypothesis can be defined as:
<em>H₀</em>: The proportion of people in Norway with a blood type of A positive is 36%, i.e. <em>p</em> = 0.36.
<em>Hₐ</em>: The proportion of people in Norway with a blood type of A positive is different from 36%, i.e. <em>p</em> ≠ 0.36.
The test statistic is:

The information provided is:
<em>p</em> = 0.36
<em>n</em> = 150
Compute the standard deviation used in the test statistic as follows:



Thus, the standard deviation used in the test statistic is 0.04.
Answer:
The percentage is 36%
Step-by-step explanation:
We are given
Shade the grid to represent the ratio 9/25
so, we have ratio as

we know that for finding percent , we multiply ratio by 100
so, we can multiply by 100 here

now, we can simplify it


So,
The percentage is 36%
