Annual snowfall in Anchorage, Alaska, is normally distributed with a mean height of 76 inches and a standard deviation of 4.7 inches. What is the probability this year that it will snow between 71.4 and 80.7 inches in Anchorage? 67.75% 54.71% 38.14% 23.22%

Answers

Answer 1

Answer:

67.75%

Step-by-step explanation:

Given:

Given that:

µ = 76 ; σ = 4.7

P(x < 80.7) - P(x < 71.4)

Obtain the standardized score, Z ; x = 71. 4

Zscore = (x - μ) / σ

P(x < 71.4) = (71.4 - 76) / 4.7

P(x < 71.4) = - 4.6 / 4.7

P(x < 71.4) = - 0.9787

P(z < 0.9787) = 0.16386

x = 80.7

P(x < 80.7) = (80.7 - 76) / 4.7

P(x < 80.7) = 4.7 / 4.7

P(x < 80.7) = 1

P(z < 1) = 0.84134

0.84134 - 0.16386 = 0.67748 = 67.748% = 67.75%

Find two positive consecutive integers such that the square of the first added to three times the second is 24

Answers

Answer:

3 and 5

Step-by-step explanation:

Let the two consecutive odd integers be x and x + 2.

Now,

The given statement is

[tex]x^2 + 3 \times (x+2)=24\\x^2 + 3x+6-24 = 0 \\x^2 + 3x-18 = 0\\x^2+6x-3x-18=0\\x(x+6)-3(x+6)=0\\(x-3)(x+6)=0\\x=3,-6[/tex]

Taking x=3.

Hence, two consecutive odd integers are 3 and 5.

Answer:

[tex](17a-1)(x+1)[/tex]

Step-by-step explanation:

Given: Expression is [tex]17ax+17a-x-1[/tex]

To factor: the given expression

Solution:

Take [tex]17a[/tex] common from the first two terms and [tex]-1[/tex] from the last two terms.

[tex]17ax+17a=17a(x+1)[/tex]

and

[tex]-x-1=-(x+1)[/tex]

So,

[tex]17ax+17a-x-1=17a(x+1)-1(x+1)\\=(17a-1)(x+1)[/tex]

Therefore,

Answers

Answer:

Volume of replica = 625 cubic inches

Step-by-step explanation:

Height of the gold statue = 80 inches

Volume of the gold statue = 320 cubic inches

Height of the replica = 100 inches

Dimensional scale factor = [tex](\frac{\text{Dimension of the replica}}{\text{Dimension of the original statue}})[/tex]

                                      = [tex]\frac{100}{80}[/tex]

                                      = 1.25

Volume scale factor = [tex]\frac{\text{Volume of replica}}{\text{Volume of original}}[/tex]

Since, volume scale factor = (Dimensional scale factor)³

[tex]\frac{\text{Volume of replica}}{\text{Volume of original}}=(1.25)^3[/tex]

Volume of replica = (1.25)³ × Volume of original statue

                              = (1.25)³ × 320

                              = 625 cubic inches

D is the answer since you added all the numbers together ten divide by five

Answer:

D

Step-by-step explanation:

We need to find the missing value to make sure it averages out to 250.

So they will be 5 rounds of different scores.

Since we dealing with averages, we need to set up a

equalivent equation to 250. We would add up all our previous scores and try to find the new x score and divide it by 5 and set it equal to 250. So our equation will look like.

Let x represent of our next game.

[tex] \frac{236 + 274 + 246 + 236 + x}{5} = 250[/tex]

Multiply by 5 both sides

[tex]236 + 274 + 246 +236 + x = 1250[/tex]

[tex]992 + x = 1250[/tex]

[tex]x = 258[/tex]

Answers

Step-by-step explanation:

The Triangle Inequality Theorem states that any two sides of the triangle must add up to be greater than the third side.

Question #1

Here we have a triangle that has side lengths of 10 in, 11 in, and ? in.

This last side length must add up to 10 in to be greater than 11 in.

The least possible whole number that would fit this description would be 2 in.

10 in + 2 in > 11 in10 in + 11 in > 2 in 11 in + 2 in > 10 in

The missing side length should be labeled as 2 inches.

Question #2

We are given a triangle with side lengths of 6 in and 8 in. We are asked to choose all answers that apply from this list:

2 in3 in4.5 in 6.5 in10 in13.5 in14 in15.5 in

We can tell that 2 in cannot be an answer since 6 in + 2 in is not greater than 8 in.

We also know that 14 in and 15.5 in cannot be part of the answer choices since 8 in + 6 in = 14 in, and this is not greater than 14 in or 15.5 in.

The rest of the answer choices will form a triangle if we follow the Triangle Inequality Theorem. You can test it out yourself to check.

Therefore, the answer choices are:

B. 3 inC. 4.5 inD. 6.5 inE. 10 inF. 13.5 in Question #3

We are given these possible side lengths:

2, 4, 5, 6, 10

Let's test out which combinations will create a triangle.

2 + 4 > 5 5 + 2 > 44 + 5 > 2

The straw lengths 2, 4, and 5 will form a triangle.

2 + 5 > 6 5 + 6 > 22 + 6 > 5  

The straw lengths 2, 5, and 6 will form a triangle.

2 + 6 > 4 4 + 2 >/ 6

The straw lengths 2, 4, and 6 will NOT form a triangle.

4 + 5 > 66 + 5 > 4 4 + 6 > 5

The straw lengths 4, 5, and 6 will form a triangle.

5 + 6 > 10 10 + 5 > 66 + 10 > 5

The straw lengths 5, 6, and 10 will form a triangle.

We have no more straw lengths that will form a triangle, since adding up each remaining pair of given straw lengths do not output a value greater than another number.
