Step-by-step explanation:
Make a table to find the values of x
P.s pick random y value
When x is 1,
y is 4........ Plug 1 into the equation ur given u get the value of y. So, 2(1)+2
When x is 2,
y is 6......... Plug 2 into the equation ur given u get the value of y. So, 2(2)+2
So this point is (2,6)
When x is 3
y is 8 ......2(3)+2
So this point is (3,8)
When x is 4
y is 10.... 2(10)+2
So this point is (4,10)

Given:
Drawing a vowel from letter tiles that spell out MATHEMATICS.
Chances =
To find:
The correct values for the blanks.
Solution:
Vowels are a, e, i, o, u.
In MATHEMATICS, the vowels are A, E, A, I.
Number of vowels = 4
We know that,
So, the chance of drawing a vowel from letter tiles that spell out MATHEMATICS is .
Blank 1: 1
Blank 2: 4
Therefore, the value for blank 1 is 1 and the value for blank 2 is 4.
Answer:
0.421
Step-by-step explanation:
There are two diagrams, one for 0.137, and one for 0.284.
I'll go place by place from least to greatest.
First, add 7 thousandths and 4 thousandths.
That will equal 11 thousands. That's greater than 9, so add 1 hundredth to the equation.
(0.1 + 0.2) + (0.03 + 0.08 + 0.01) + 0.001
Now, add 3 hundredths and 8 hundredths.
That will equal 11 hundredths. Add the other hundredth from the regrouping of the thousands for 12 hundredths. That is also greater than 9, so add 1 tenth to the quation
(0.1 + 0.2 + 0.1) + 0.02 + 0.001
Then, add 1 tenth and 2 tenths.
That will equal 3 tenths. Add the other tenth from the regrouping of the hundredths to get 4 tenths.
0.4 + 0.02 + 0.001
Now add 0.4, 0.02, and 0.001.
0.42 + 0.001
0.421
The answer to 0.137 + 0.284 equals 0.421.
The solution for this problem is:
The x-bar or the mean is = 150Confidence level is 80%sample size is 36
E = t*s/sqrt(n)= 1.3062*40/sqrt(36)=1.3062 * 6.66667= 8.708
An 80% Confidence Interval is: 150-8.708 < u < 150+8.708Or141.3 < u < 158.7 is the confidence interval
