Probability and Statistics Normal Distribution Test For questions, 1-5 assume that a normal distribution has a mean of 85 and
a standard deviation of 5. Label the graph to accurately reflect this, and
then find the percentages of the data that falls within the specified area
asked by the questions.
1. Between the values of 80 and 90.
2. Between the values of 85 and 95
3. Above 90
4. Below 85
5. Below 95 and above 85
For the following problems, find the area under the standard normal curve.
6. To the left of z = -1.08
7. To the right of z = 1.35
8. Between z= -2.25 and 2 = 2.25
9. To the left of z = -1.45 and to the right of z = 1.96

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =

1.3 =x

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
