Simplify the ratio 100:120

Answer

The area of the shaded region under the standard normal curve is 0.4834.

Step-by-step explanation:

A random variable X is said to have a normal distribution with mean, µ and variance σ².

Then , is a standard normal variate with mean, E (Z) = 0 and Var (Z) = 1. That is, Z  N (0, 1).

The distribution of these z-variates is known as the standard normal distribution.

Compute the area under the curve between -2.13 and 0 as follows:

Thus, the area of the shaded region under the standard normal curve is 0.4834.

Answer:

B. 7ab²c

Step-by-step explanation:

The GCF of 21a²b^4c and 49ab²c³ is

7ab²c

Answer:

The correct answer is b.

Step-by-step explanation: I had that q and got it right

Answer:

Kindly check explanation

Step-by-step explanation:

Number of clubs = 13

Number of face cards = 12

Number of hearts = 13

Number of King's = 4

Number of reds = 26

Number of spade = 13

Number of 6's = 4

Total possible outcomes = total number of cards = 52

Probability = required outcome / Total possible outcomes

1.) P(A club) = 13 / 52

2.) P(face card or heart) =

p(face card) + p(heart)

12 / 52 + 13/52

= (12 + 13) / 52 = 25 /52

3.)

(A 6 and a spade)

4/52 * 13/52

= 52 / 2704

= 1/52

4.) A king

P(king) = 4 /52 = 1/13

5) A red

P(red) = 26 / 52 = 1/2

Answer:

The answer is A

Step-by-step explanation:

Answer:

y=-1/4x - 2

Step-by-step explanation:

gradient of perpendicular lines is got by :M1M2= -1

y =4/3x + 6 rearrange 3y = 4x + 18

gradient is 4

4M2 =-1

M2 =-1/4

then is -2

hence y = mx + c is y = -1/4 x -2

Answer:

y = 41.603X + 3.582

Step-by-step explanation:

Given the data:

Week ___Price ____ Sales

1 _______.33 _______20

2 ______ .25 _______ 14

3 ______ .44 _______ 22

4 ______ .40 _______ 21

5 ______ .35 _______ 16

6 ______ .39 _______ 19

7 ______ .29 _______ 15

Using the linear regression calculator ; The regression equation obtained is :

y = 41.603X + 3.582

Where ;

y = sales (predicted variable)

x = price (predictor variable)

Slope = 41.603

Intercept = 3.582

Answer:

f(1) = 2

Step-by-step explanation:

Since f(x) = x^4 + 4 x^3 + 5 x^2 - 4 x - 4

When we evaluate this for x = k = 1, we replace x with the value 1 as shown below:

f(1) = 1^4 + 4 * 1^3 + 5 * 1^2 - 4 * 1 - 4 = 1  + 4 + 5 - 4 - 4 = 10 - 8 = 2

Answer:

I have no clue.,...

[tex]f(8)=6\cdot8-4=48-4=44[/tex]

Answer:

substitute x therefore 6*8=48

48-4=44

Answer:

turn it 90 degrees, hope this helps

Step-by-step explanation:

Answer:

so go to the 120 degree line and make sure the line is straight across from zero and thin dray a line going from 120 down to the bottom of where the zero is  

Step-by-step explanation:

788% gdkgdkgdkgdkgdkgdkgdk

first find the gradient.

y2 - y1 / x2 - x1 = ((-1) - (-6)) / (1 - 2) = 5 / -1 = -5

Then find the equation of the line

y - y1 = m(x - x1)

y - (-2) = -5(x - 2)

y + 2 = -5x + 10

y = -5x + 10 - 2

y = -5x + 8

So the equation of the line is y = -5x + 8

Answer:

-30

Step-by-step explanation:

In g(8) the 8 = n.  So, substitute 8 in for n in the expression -4n + 2

g(8)  =  -4(8) + 2 = -32 + 2 = -30

Answer:

-30

Steps:

For this you just have to replace the "n" with the 8. make sure you put it parentasies.

Answer:

First, set up equations for total cost for both Happy Paws and Woof Watchers.

x= number of hours

y= total cost

Happy Paws

y=3.50x +16

Woof Watchers

y=4.75x+11

4.75x+11=3.50x+16

x=4

You can check your answer by doing the following:

Happy Paws: (3.50)(4)+16= 30

Woof Watchers: (4.75)(4)+11= 30

Answer:

0.16

Step-by-step explanation:

The computation of the minimum no of usual smokers expected to get out of 20 adults is shown below:

Here the standard deviation is

[tex]= \sqrt{npq} \\\\= \sqrt{20\times 0.18 \times (1 - 0.18)}\\\\= \sqrt{20\times 0.18\times 0.82}\\\\= \sqrt{2.952}[/tex]

= 1.72

Now the minimum no of smokers is

[tex]= np - 2\times 1.72\\= 20 \times 0.18 - 3.44\\\\= 0.16[/tex]
