Answer:

0.9962

Step-by-step explanation:

The objective of this question is to determine the proportion of average city temperature that is lower than that of Singapore.

Suppose X is a random variable that follows a normal distribution:

Then;

[tex]X \sim N ( \mu = 20.66, \sigma = 2)[/tex]

[tex]P(X< 26) = P \bigg ( Z < \dfrac{26 - 20.66}{2} \bigg)[/tex]

[tex]P(X< 26) = P \bigg ( Z < \dfrac{5.34}{2} \bigg)[/tex]

[tex]P(X< 26) = P \bigg ( Z < 2.67\bigg)[/tex]

From the z tables;

P(X< 26) = 0.9962

Thus, there is 0.9962 proportion of average city temperature are lower than that of Singapore.

Answer:

0.9962

Step-by-step explanation:

A set of average city temperatures in May are normally distributed with a mean of 20.66 degrees and a standard deviation of 2 degrees. The average temperature of Singapore is 26 degrees

What proportion of average city temperatures are lower than that of Singapore?

Solution:

The z score shows the number of standard deviations by which the raw score is above or below the mean. If the raw score is above the mean then the z score is positive but if the raw score is less than the mean then the raw score is negative. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma}\\\\where\ x=raw\ score, \mu=mean,\sigma=standard\ deviation[/tex]

Given that μ = 20.66, σ = $2

For the average temperature of Singapore of 26°, the z score is:

[tex]z=\frac{x-\mu}{\sigma}=\frac{26-20.66}{2} =2.67[/tex]

From the normal distribution table, P(x < 26) = P(z < 2.67) = 0.9962

Answer:

Step-by-step explanation:

For club 1 - 2 book

For club 2 - 4 books

Club 1 has a $40 fee + 2 books = $60 in total

Club 2 has a $0 fee + 4 book = $60 in total

I'm pretty sure I'm right

Answer:

There would have to be 2 books purchased from the first club. Then, there would have to be 4 books purchased from the second club.

Step-by-step explanation:

1st club.  (cost of club) 40$ + (cost of 2 books) 20$ = 60$.

2nd club. (cost of books) 15$ x  (how many books) 4 = 60$

Answer:

Step-by-step explanation:

(92 - 12) – 4 = 2 (2 + for

I

Answer:

Step-by-step explanation:

4x - 9 = 35                   Add 9 to both sides

4x - 9 +9 = 35 + 9        Combine like terms

4x = 44                         Divide both sides by 4

4x/4 = 44/4                  Complete the division

x = 11

Answer: Small box = $5

Large box = $14

Step-by-step explanation:

Let the cost of a small box be a

Let the cost of a large box be b

The scenario in the question can be modelled into an equation as:

3a + b = 29 ....... equation i

3a + 4b = 71 ....... equation ii

Subtract equation ii from equation I

-3b = -42

b = 42/3

b = 14

Cost of large box = $14

We put the value of b into equation I

3a + b = $29

3a + $14 = $29

3a = $29 - $14

3a = $15

a = $15/3

a = $5

Cost of small box = $5

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

Since the triangles are congruent then corresponding sides are congruent, then

CA = NE , that is

4x + 3 = 11 ( subtract 3 from both sides )

4x = 8 ( divide both sides by 4 )

x = 2

----------------------------------------

AR = EW, that is

4y - 12 = 10 ( add 12 to both sides )

4y = 22 ( divide both sides by 4 )

y = 5.5

-------------------------------------------

NW = x + y = 2 + 5.5 = 7.5

CR = NW = 7.5

Answer:

The slope is -3

Step-by-step explanation:

Find 2 points (-2,3) (-1,0) are 2.

Next subtract y 1 by y 2  in this example, 3-0 which equals 3

After that, subtract x 1 and x 2. In this example, -2-(-1) which equals -1.

Now dive y over x.  3/-1 or -3.

So the slope is -3.

Answer:

484 : 1

Step-by-step explanation:

We can write white blood cells to:

22^5 = 22 × 22 × 22 × 22 × 22

We can write red blood cells to:

22³ = 22 × 22 × 22

Thus, white : red equals

22 (5 times) : 22 (3 times)

22² : 22^0 = 484 : 1

I hope this helps you :)

The required ratio of white blood cells to red blood cells is 1:484.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
A cubic millimeter of blood contains 22³, white blood cells, and 22⁵ red blood cells.

The ratio of white to red blood cell is given as,
Ratio = 22³/22⁵
Ratio = 1 / 484

Thus, the required ratio of white blood cells to red blood cells is 1:484.

12, 17, 14

10, 15, 19

12, 17, 14

14, 18, 16  = 14(even), 18(even), 16(even) = cannot be the correct answer

19, 12, 15  = 19(odd), 12(even), 15(odd) = cannot be the correct answer

12, 17, 14  = 12(even), 17(odd), 14(even) = is the correct answer

10, 15, 19  = 10(even), 15(odd), 19(odd) = cannot be the correct answer

Answer:

Step-by-step explanation:

to know:

-to be paralel the lines have to have the same slope

-to be perpendicular the slope has to be negative invers of thhe other

-to be neither has to be none of the above two

equation to compare to is

y=mx+b where m is the slope

if your equation does not have this form make it have this form

2y=3x+1 so divide by 2

y=[tex]\frac{3}{2}[/tex] x+1 so here the slope is [tex]\frac{3}{2}[/tex]

4x+6y=14 so subtract 4x and then divide by 6 to isolate y

6y= -4x+14

y=[tex]\frac{-4}{6}[/tex]  x + [tex]\frac{14}{6}[/tex]  symplify

y=[tex]\frac{-2}{3}[/tex] x + [tex]\frac{7}{3}[/tex]  so the slope here is [tex]\frac{-2}{3}[/tex]

So if you compare the slopes you can see that are negative reciprocal of eachother so the lines are perpendicular

and so on...

Answer:

220 i think but im not sure

Step-by-step explanation:

Answer: x = 40

have: ∠A + ∠B + ∠C + ∠D = 180°

⇔ x + 6 + x + 4 + x +10 + x = 180°

⇔ 4x + 20 = 180

⇔ x = (180 - 20)/4

⇔ x = 160/4 = 40
