PLEASE HELP ME WITH THIS ALGEBRA QUESTION!! THANK YOU!!

Place the midpoint of the protractor on the VERTEX of the angle.

Line up one side of the angle with the zero line of the protractor (where you see the number 0).

Read the degrees where the other side crosses the number scale.

hoped it helped :)

Answer:

52-32

Step-by-step explanation:

Answer:

0.4246

Step-by-step explanation:

Given data:

mean ( u ) = 15 inches

std ( б )= 6 inches

sample size( n ) = 46

ux = mean sample length

Determine the probability that x within 0.5 inch of the claimed population mean

ux = u = 15

бx = б/ √ 46 =  6 /√ 46 = 6 / 6.78 = 0.88

Hence the   P( 14.5 < x < 15.5 )

= P ( [14.5 - 15 / 0.88 ] < z < (15.5 - 15) / 0.88) )

= P ( -0.5682 < z <  0.5682 )

= P ( z < 0.5682 ) - P ( z < -0.5682 )

= 0.7123 - 0.2877  ( from Z table )

= 0.4246

Answer:

88.51

0.085343

67.39

Step-by-step explanation:

Given a normal distribution :

Mean (m) = 73

Standard deviation (s) = 11

Percentage A's = 7.93% = 0.0793

Minimum score needed to receive A :

Using the Z formula

Zscore corresponding to 0.0793 = 1.41

P(x ≥ x) :

Z = (x - m) / s

1.41 = (x - 73) / 11

11* 1.41 = x - 73

15.51 = x - 73

x = 15. 51 + 73

x = 88.51

B. Students who made 57.93 or lower on the exam failedthe course. What percent of students failed the course?

P(x ≤ 57.93)

Z = (x - m) / s

Z = (57.93 - 73) / 11

Z = - 15.07 / 11

Z = - 1.37

P( Z ≤ - 1.37) = 0.085343 ( Z probability calculator)

C.) If 69.5% of the students received grades of C or better, what is the minimum score of those who received C's?

Minimum score of those who received C

Zscore corresponding to 0.695 = -0.51 (Z probability calculator)

Z = (x - m) / s

-0.51 = (x - 73) / 11

11* - 0.51= x - 73

-5.61 = x - 73

x = - 5.61 + 73

x = 67.39

Answer:

whats the question

Step-by-step explanation:

Answer:

Chris sells 5 tickets and Mary sells 16 tickets

Step-by-step explanation:

System of Equations

To solve the problem we call:

x = number of tickets sold by Chris

y = number of tickets sold by Mary

They sold a total of 21 tickets, thus:

x + y = 21            [1]

Mary sold adult tickets for $6.50 each and Chris sold student tickets for $4.00 each. The total income was:

4x + 6.5y = 124       [2]

Multiplying [1] by -4:

-4x - 4y = -84            [3]

Adding [2] and [3]:

2.5y = 40

Dividing by 2.5:

y = 40/2.5

y = 16

From [1]

x = 21 - 16 = 5

x = 5

Chris sells 5 tickets and Mary sells 16 tickets

Answer:

40 girls

Step-by-step explanation:

Set up a proportion where x is the number of girls in band class:

[tex]\frac{3}{5}[/tex] = [tex]\frac{24}{x}[/tex]

Cross multiply and solve for x:

3x = 120

x = 40

So, there were 40 girls in band class.

Answer: There are 40 girls in band class.

____________________________________________________________

The ratio for this problem is:

[tex]\frac{3}{5} = \frac{24}{x}[/tex]

To get from 3 to 24, you would multiply by 8. You need to do the same thing to 5 to get x.

5 times 8 equals 40.

There are 40 girls in band class.

Solution :

Equation for Malcom's family travels after t hours is d = 65 t

From the graph, equation for Theo's family travels after travels after t hours is

[tex]$d=\frac{225}{4.5}t$[/tex]

[tex]$d=50 t$[/tex]

For Malcom's family, speed [tex]$= \frac{d}{t}$[/tex] = 65 miles per hour

For Theo's family, speed [tex]$= \frac{d}{t}$[/tex] = 50 miles per hour

Malcom's family traveled faster than Theo's family by

        = (65-50) miles per hour

        = 15 miles per hour

Answer

A. 42 tickets

Explanation

Since everyone must go on the ride together the number of tickets must be a multiple of 8 (since there are 8 people). 42 is the only number that is not a multiple of 8.

Answer:

<ECF = 45 degrees

Step-by-step explanation:

If ABCD is a square, then the diagonal AC divides angle <C and angle <A  in two equal parts. Angles A and C are also 90 degrees each due to the act that the figure is a square. Therefore their bisection would render 90/2 = 45 degrees.

Notice as well that angle <ECF is opposite by the vertex to one of these 45 degree angles, and then it must measure the same amount (45 degrees).

So, <ECF = 45 degrees

1 and 2/5 and 2 and 2/5

A fraction represented with its quotient and remainder is a mixed fraction. 1 2/5 and 2 2/5 are two mixed numbers that have a sum of 3 4/5.

What is Mixed Fraction?

A fraction represented with its quotient and remainder is a mixed fraction.

We need to find the two mixed numbers whose sum is 3 4/5.

The sum of two mixed numbers is 3 4/5 which is also equal to 19/5.

1 2/5+2 2/5

=7/5+12/5

=19/5

Now 3 4/5=19/5

Therefore 1 2/5 and 2 2/5 are two mixed numbers whose sum is 3 4/5

Step-by-step explanation:

The  probability that at least one of the next five birds he sees is a robin is 0.75.

Based on the stimulation result shown on the table we can seen that other birds appeared at least 15 times.

Hence:

P(A)=15/20

P(A)=0.75

Therefore the  probability that at least one of the next five birds he sees is a robin is 0.75.
