Answer:

53

Step-by-step explanation:

in rhombus, opp angeles are equal.

4x+9 =(11x-3)/2--ac bisects the angle dab

8x+18 = 11x-3

3x = 21

x=7

angle dab = 11*7-3/(2)= 77-3/(2)= 74/2= 37

total of angles = 180

74+2x = 180

2x = 106

x=53

You can use Excel to make the graph, but other free options work just fine. I used LibreOffice to make the graph shown below.

Each point on the line graph represents a frequency for a given time value. The first point being 4 units high, means there were 4 customers at 8:00 AM. Then there were 6 customers at 9:00 AM, meaning the next dot has a height of 6. And so on.

The graph shown below matches with choice B.

B

Answer:

The height of the giraffe is 27.432 decimeters.

Step-by-step explanation:

To convert 1 foot to decimeters you would multiply by 3.048.

We need to multiply 9 feet by 3.048 which would give you the answer of 27.432 decimeters.

Answer:

[tex]4x+3y\leq-3[/tex]

Step-by-step explanation:

Take a random included point for both x and y and compare it with -3:

[tex]x=-5,y=2[/tex]

[tex]4x+3y[/tex]

[tex]4(-5)+3(2)[/tex]

[tex]-20+6[/tex]

[tex]-14<-3[/tex]

We can see that since -14 is less than -3, and the fact that the line is solid, we can conclude that the inequality is [tex]4x+3y\leq-3[/tex]

The inequality that represents the shaded region is 4x + 3y ≤ - 3.

Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.

The symbol a < b indicates that a is smaller than b.

When a > b is used, it indicates that a is bigger than b.

a is less than or equal to b when a notation like a ≤ b.

a is bigger or equal value of an is indicated by the notation a ≥ b.

Given a line 4x + 3y = - 3 with no dotted line and the shaded region is less than or equal to the line 4x + 3y = - 3.

∴ The inequality that represents this shaded region is 4x + 3y ≤ - 3.

Using the normal distribution, it is found that there is a 0.6568 = 65.68% probability that the variable that is between −1.33 and 0.67.

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 a standard normal distribution, hence [tex]\mu = 0, \sigma = 1[/tex].

The probability that the variable is between −1.33 and 0.67 is the p-value of Z when X = 0.67 subtracted by the p-value of Z when X = -1.33, hence:

X = 0.67

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

[tex]Z = \frac{0.67 - 0}{1}[/tex]

[tex]Z = 0.67[/tex]

[tex]Z = 0.67[/tex] has a p-value of 0.7486.

X = -1.33

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

[tex]Z = \frac{-1.33 - 0}{1}[/tex]

[tex]Z = -1.33[/tex]

[tex]Z = -1.33[/tex] has a p-value of 0.0918.

0.7486 - 0.0918 = 0.6568.

0.6568 = 65.68% probability the variable that is between −1.33 and 0.67.

Check the picture below.

we know that AL is an angle bisector, so the angle at A gets cuts into two equal halves, we also know the angle at B is 30°, so the triangle ABC is really a 30-60-90 triangle, meaning the angle at A is really a 60° angle, cut in two halves gives us 30° and 30° as you see in the picture.

if the angles at A and B, inside the triangle ABL, are equal, twin angles are only made in an isosceles by twin sides, that means that AL = BL.

Looking at the triangle ALC, we can see is also another 30-60-90 triangle, and we can just use the 30-60-90 rule to get x=CL.
