Answer:

72

Step-by-step explanation:

For Q 1 : 25 % of the scores are below this value. The area under the bell-shaped curve of the normal distribution is 0.25. And since we have 288 electricians that took a certification test:

0.25 * 288 = 72.

Step-by-step explanation:

1. 10-(2+3) = 5

2. 2x3 - 10 = -4

3. 3 x (4-2) = 6

4. (3+5) / 4 = 2

5. (5-2) x 3 = 9

6. (9-4) + 5 = 10

Answer:

1. 50 m

2. 80 cm

Step-by-step explanation:

1. There are 2 triangles, subtract the area of 1 of them from the other.

The triangle that needs to be subtracted: b = 20 m, h = 10 m

A = 1/2b * h = 1/2(20) * 10 = 10*10 = 100 m

The big triangle, the one that needs to be subtracted plus the one you need to find the area of: b = 20 cm, h = 15 cm, 1/2(20) * 15 = 10 * 15 = 150

150 - 100 = 50 c

2. Divide it into 3 parts:

1- 3*4 = 12

2. 7*(4 + 4) = 7*8 = 56

3. [(4 + 4) * (13 - 7 - 3)]/2 = (8*3)/2 = 24/2 = 12

12 + 56 + 12 = 80 cm

Answer:

i think 7

Step-by-step explanation:

Option B: SEVEN

The number that goes not belong in the following series is SEVEN

Given :

The numbers in the series is

2 - 5 - 7 - 14 - 41 - 122 - 365 - 1094 - 3281

First number is 2

[tex]2 \cdot 3 -1=5\\[/tex]

Lets multiply the previous term by 3  and subtract 1 to check the other terms

[tex]5 \cdot 3 -1= 14\\14 \cdot 3 -1= 41\\41 \cdot 3 -1= 122\\122 \cdot 3 -1= 365\\365 \cdot 3 -1= 1094\\1094 \cdot 3 -1= 3281\\[/tex]

From the series we can see that 7 does not belong to the series .

So,  SEVEN does not belong to the series .

Answer:

B. 20 weeks

Step-by-step explanation:

I am using the graphing calculator my school uses for exams. But here is the step by step anyway

5x + 36 = 2x + 96

(5x - 2x) + 36 = (2x - 2x) + 96

3x + 36 = 96

3x  + (36 - 36) = (96 - 36)

3x = 60

(3x ÷ 3) = (60 ÷ 3)

x = 20

x represents weeks

Answer:

C. 10

Step-by-step explanation:

There are 5 choices of carpet, and 2 choices of wallpaper. This means that there are only 10 possible outcomes.

The total number of possible outcomes when you select one color of wallpaper and one color of carpet is,

⇒ 10

A combination is a technique to determines the number of possible arrangements in a collection of items where the order of the selection does not matter.

Given that;

You choose between red or yellow wallpaper,

And, orange, red, green, blue, or purple carpet.

Since, There are 2 wallpapers.

And, There are 5 carpets.

Hence, The total number of possible outcomes when you select one color of wallpaper and one color of carpet is,

⇒ ²C₁ × ⁵C₁

⇒ 2 × 5

⇒ 10

Thus, The total number of possible outcomes when you select one color of wallpaper and one color of carpet is, 10

Answer:

25 .2 is answer

Step-by-step explanation:

Answer:

Part A: 56

Part B: 43.9

Part C: I think the medain is more apropriate in this situation because it takes out the outlier , 3, that is affecting the mean

Step-by-step explanation:

Part A: To calculate the median you must have all of the numbers in numerical order so, 3,31,37,56,57,61,62, The medain is the number in the middle or closet to the middle. In this case 56 is directly in the middle so 56 is your median.

Part B: To find the mean you must add all of the values together and then divide by the number of values you have so when you add 3+31+37+56+57+61+62 it equals 307 and you divide it by 7 because there are 7 numbers in this data set and you get 43.9 when you round to the nearest tenth.

Part C: explanation in answer.

Answer:

Area: 312

Perimeter: 75

Step-by-step explanation:

Area is l·w

20·16=320

two corners aren't filled

320-9-9=318

Add all the sides for perimeter

17+3+3+13+20+13+3+3=75

Answer:

281 m squared

Step-by-step explanation:

What we can first do is find the top length so we can do

17+3+3=23

then we can multiply it by the side length to get the whole rectangle

23*13=299

and we know each of the little areas is 9, and there are two so

9+9=18

and we can subtract that from the whole rectangle

299-18=281

Answer:

(17.91b+27)+22 is the expression

and the estimate will be 121 because u will do 18 times 4=72 and the add 22 and then 27.

Answer:

$3.50

Step-by-step explanation:

to find the range you take the highest number and the lowest number and subtract them

so with that, let us do just that-

$5.75, $3.75, $3.25, $2.25

$5.75-$2.25

=$3.5

and since we're dealing with money we must add a '0' to the end of the decimal- $3.50

good luck :)
