Consider a bell-shaped symmetric distribution with mean of 16 and standard deviation of 1.5. Approximately what percentage of da
fredd [130]

Answer: 95.45 %

Step-by-step explanation:

Given : The distribution is bell shaped , then the distribution must be normal distribution.

Mean : \mu=\ 16

Standard deviation :\sigma= 1.5

The formula to calculate the z-score :-

z=\dfrac{x-\mu}{\sigma}

For x = 13

z=\dfrac{13-16}{1.5}=-2

For x = 19

z=\dfrac{19-16}{1.5}=2

The p-value = P(-2

0.9772498-0.0227501=0.9544997\approx0.9545

In percent, 0.9545\times100=95.45\%

Hence, the percentage of data lie between 13 and 19 = 95.45 %

​Which values are solutions to the inequality? ​ ​5r≤6r−8​ ​ Select each correct answer. r = 7 r = 8 r = 9 r = 10
Ratling [72]

Answer:

r = 8,9,10

Step-by-step explanation:

The given inequality is :

​5r≤6r−8​  ...(1)

We need to find the value of r.

Subtracting 5r to both sides of the inequality .

​5r-5r≤6r-5r−8

0≤r−8

r ≥ 8

Hence, the values of r are 8,9,10.

(I'm so lost I need help with this question!!!)
lozanna [386]

Answer:

1. 5 cm

2. 7.07 cm

Step-by-step explanation:

According to your provided information, the area of a square is A = s^2. They also tell you that the area of the square in the picture is 25cm^2. That means that, to find the length of any side (s), you just need to plug 25 in as the area. So

25 = s^2 ... Take the square root of both sides to isolate s.

s = ±5 ... But since we're talking about length, we only take the value positive five. (Length can't be a negative value.)

Now we have the length of any side as 5 cm, and they want us to find the length of the diagonal. We can use the Pythagorean theorem, a^2 + b^2 = c^2, where c will be the diagonal we want. We can do this because we know that ANY side of this square is s = 5, so if we plug that into a^2 + b^2 = c^2, we get

5^2 + 5^2 = c^2 ... 5 times 5 is 25

25 + 25 = c^2 ... Add

50 = c^2 ... Take the square root of both sides

c = √50 ... Use a calculator

c ≈ 7.07

Write an equation of the line passing through the points (3,7) and (-1,-13)
kykrilka [37]

Answer:

Step-by-step explanation:

(-13 - 7)/(-1 + 3) = -20/2 = -10

y - 7 = -10(x - 3)

y - 7 = -10x + 30

y =  - 10x + 37
