Answer:

D) Triangle AEB and triangle DEC

Step-by-step explanation:

We are given the equation:

25 - b² = 4b

it can be simplified into the following:

b² + 4b - 25 = 0

In this simplified equation, we can see that it is very similar to the general form of a quadratic equation [ax² + bx + c = 0]

Therefore, we can say that the given equation is Quadratic

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

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

Step-by-step explanation:

The other graphs do not pass the vertical line test (if you draw a vertical line through the line graphed, it should pass through once), but graph c does pass the test.

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:

I believe the answer is C. 0.75

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.

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.

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:

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
