hope it helps and if it does please give a crown and save a town :)

The percentage of runners having times less than 14.4 sec is 0.15%. Then the correct option is A.

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

The times of all 15-year-olds who run a certain race are approximately normally distributed with a given mean (μ) = 18 sec and standard deviation (σ) = 1.2 sec.

The runners have times less than 14.4 sec.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

[tex]\rm z-score = \dfrac{X - \mu}{\sigma }\\\\z-score = \dfrac{14.4- 18}{1.2}\\\\z-score = -3[/tex]

Then the Percentage will be

[tex]\rm P(X < 14.4) = P(z < -3) = 0.0013499 = 0.13499\ \% \approx 0.15\ \%[/tex]

Answer:

I think it will be the first one because as we can see the points are going up which tells us the line would be positive.

Answer:

The area of a triangle can be determined with the two side lengths, the length and breadth/width multiplied.

x = unknown value of breadth/width

23 = length

506 = the area of the two lengths multiplied

23(x) = 506

/23        /23

x = 22, 22 metres is it's breadth.

Answer:

22m is the breadth of the rectangle.

Solution:

As, we know,

[tex]{ \boxed{ \pink{Area _{(rectangle)} \: = length \times breadth}}}[/tex]

➝ 506m² = l × b

➝ 506m² = 23 × b

➝ b = 506/23 = 22

Hence, Breadth of the Rectangle is 22m.

Answer:

cos F is 15/28

Step-by-step explanation:

Use SOH CAH TOA

CAH is for cosine and it's Adjacent over Hypotenuse

the adjacent side of F is 15 and the hypotenuse is 28

So 15/28 which does not simplify

Answer:

60=3x+27(The corresponding elements of the angular triangles are similar.)

60-27=3x

33=3x

33/3=3x/3

11=x

x=11

Assuming that this is a parallelogram, that means the angle opposite each other like Angle L to Angle J and Angle K to Angle M are equal in angle measure.

Thus Angle L is 98 degrees like Angle J

B. 3(x + 2y + 1)

Step-by-step explanation:

You can expand 3(x + 2y + 1) by multiplying 3 by each thing in the brackets:

3(x + 2y + 1) is the same as 3x + 6y + 3

Hope this helps!

Answer:

The answer is B because of factorization and the distributive law.

if the -8-13 are both in the denominator

-24/(-8-13)

-24/-21

divide both sides by -3

[-24/-3] / [-21/-3]

8 / 7

if the -13 comes after the division

(-24/-8) -13

Step-by-step explanation:

geometric sequence means that every term is created by multiplying the previous term by a constant factor.

we can see the constant factor directly, I am sure, but let's do it formally correct :

-1/8 × f = -1/4

f = -1/4 / -1/8 = -1/4 × -8/1 = -8/-4 = 2

so, yes, every new term of the sequence is created by multiplying the previous term by 2.

a0 = -1/8

a1 = a0 × 2 = -1/8 × 2 = -2/8 = -1/4

a2 = a1 × 2 = a0 × 2×2 = -1/8 × 2×2 = -1/8 × 4 = -4/8 = -1/2

...

an = a0 × 2^n = -1/8 × 2^n

a6 = -1/8 × 2⁶ = -1/8 × 64 = -8

so, the only questing is, where does your teacher start the count for such a geometric sequence ?

do you call the first term a0 or a1 ?

my solution above starts with a0.

but if it should start with a1, then we need to reduce the exponents of 2 by 1 :

an = -1/8 × 2^(n-1)

and a6 would be

a6 = -1/8 × 2⁵ = -1/8 × 32 = -4
