Using the normal distribution, it is found that there is a 0.0228 = 2.28% probability that a diode selected at random would have a length less than 20.01mm.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, we have that:

The probability that a diode selected at random would have a length less than 20.01mm is the p-value of Z when X = 20.01, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{20.01 - 20.05}{0.02}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a p-value of 0.0228.

0.0228 = 2.28% probability that a diode selected at random would have a length less than 20.01mm.

Answer:

The answer would be 48

Sydney is 48

Devaughn is 62

48 + 62 = 110

Okays so you start by doing the equation 110 - 14 = 96

then dividing 96 by 2 (96 ÷ 2) which is 48

add 14 to 48 and you will get 62. We can automatically assume that sydney is 48 because when you add 48 to 62, you will get 110. I hope that this helps! ^‿^

========================================================

The card says we need 1 & 1/2 cups of flour

Let's convert this to decimal form

1 & 1/2 = 1 + 1/2

1 & 1/2 = 1 + 0.5

1 & 1/2 = 1.5

The mixed number 1 & 1/2 is equivalent to the decimal number 1.5

Now multiply this by 3. This is because the recipe originally serves 10 people, but we want to serve 3 times as many people (3*10 = 30 total).

So,  3*1.5 = 4.5

Now convert back to a mixed number

4.5 = 4 + 0.5

4.5 = 4 + 1/2

4.5 = 4 & 1/2

We'll need 4 & 1/2 cups of flour.

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

Here's another way to approach the problem

Multiply 3 by 1 & 1/2 to get

3*(1 & 1/2) = 3*(1 + 1/2)

3*(1 & 1/2) = 3*1 + 3*1/2

3*(1 & 1/2) = 3 + 3/2

3*(1 & 1/2) = 3 + (2+1)/2

3*(1 & 1/2) = 3 + 2/2 + 1/2

3*(1 & 1/2) = 3+1 + 1/2

3*(1 & 1/2) = 4 + 1/2

3*(1 & 1/2) = 4 & 1/2

Answer:

A)Percentile for Lynette, the student who is 65 in. tall is 36th

B) Asher is 22 inches tall.

Step-by-step explanation:

Percentile : It is a measure used in statistics indicating the value below which a given percentage of observations in a group of observations falls

A) Find the Percentile for Lynette, the student who is 65 in. tall.

No. of students below 65 inch =9

So, Percentage of data below 65 inch =[tex]\frac{9}{25} \times 100 = 36 \%[/tex]

So, Percentile for Lynette, the student who is 65 in. tall is 36th

B)Ashers height is at the 88th percentile of the distribution. Interpret this value in context. How tall is Asher

[tex]88=\frac{x}{25} \times 100 \\\frac{2200}{100}=x[/tex]

22=x

So, No. of students below or st 88th percentile = 22

So, Asher is 22 inches tall.

Answer:

The expression which represents the total number of miles he jogs in a week is 7 m ⇒ A

Step-by-step explanation:

Let us solve the question

∵ Dominic goes jogging every morning

∵ m represents the number of miles he jogs each day

→ That means he jogs m miles every day

∵ There are 7 days in a week

→ That means he jogs m miles every day for 7 days

∵ m + m + m + m + m + m + m = 7 × m

∴ He jogs in 1 week 7 × m miles

∴ He jogs 7 m miles in a week

The expression which represents the total number of miles he jogs in a week is 7 m

Answer:

y=mx-22

Step-by-step explanation:

Take standard line equation y=mx+c and substitute the given values of m=4, x=6, y=2 to find out the value of c

The general equation of a straight line in slope-intercept form is given as:

y = mx + c

The slope-intercept form of 6x - 10y = 20 is y = (3/5)x - 2.

The equation of a line is a form of representing the set of points, which form a line in a coordinate system. 

The general equation of a straight line is given as:

y = mx + c,

where m = slope of the line and c = y-intercept.

We have,

6x - 10y = 20 _____(1)

The slope intercept form is  y= mx + c

So,

Subtract -6x on both sides.

6x - 10y - 6x = 20 - 6x

-10y = 20 - 6x

Divide both sides by -10.

y = 20/-10 + 6x/10

y = -2 + 3x/5

y = (3/5)x - 2

Thus,

The slope-intercept form of 6x - 10y = 20 is y = (3/5)x - 2.

                 Statement                               Reason                  

⇒ ∠2 = ∠5 = ∠6 = 3x + 7

Looking at the picture, we can see that ∠6 and 4x + 5 are a linear pair.

Finding the value of x:

⇒ ∠6 + 4x + 5 = 180

⇒ 3x + 7 + 4x + 5 = 180

⇒ 7x + 12 = 180

⇒ 7x = 180 - 12

⇒ 7x = 168

⇒ 7x/7 = 168/7

⇒ x = 168/7 = 24

Now, substitute the value of x into the expression "3x + 7" to find ∠6.

Finding the measure of ∠6:

⇒ ∠6 = 3x + 7

⇒ ∠6 = 3(24) + 7

⇒ ∠6 = 72 + 7

⇒ ∠6 = 79°

Area of triangle= ½ ×base ×height

Substitute given information into the formula:

96= ½ ×base ×12

96= 6 ×base

Divide both sides by 6:

base= 96 ÷6

base= 16 cm

Answer:

Step-by-step explanation:

It is given that, the height of a triangle is 12cm, and its area is 96cm² and we have to find the base of triangle.

To find the base of the triangle, we have to know this formula :

[tex] \\ {\longrightarrow \pmb{\frak {\qquad \frac{1}{2} \times Base \times Height = Area_{(Triangle)} \:}}} \\ \\[/tex]

f^-1(x) = (x+10) / 2

Step-by-step explanation:

sooo

f(x) = 2x - 10

y = 2x - 10

Answer:

A function is a relation in which each input has only one output.

Step-by-step explanation:

In the relation Y is a function of X because for each input x(1,2,3 or 0) there is only one output y.

The relation that is a function is the relation (d)

From the question, we have the following parameters that can be used in our computation:

The relations (1) to (4) represent the given parameter (see attachment)

Next, we test the options

Relation (a)

This relation is not a function

This is because it fails the vertical line test i.e. some output values all point to the same input value,

Relation (b)

This relation is not a function

This is because it fails the vertical line test i.e. some output values all point to the same input value,

Relation (c)

This relation is not a function

This is because it fails the vertical line test i.e. some output values all point to the same input value,

Relation (d)

This relation is a function

This is because the inputs all point to different output values

Hence, the option (d) is a relation
