3 Tejano CDs.
What is the probability of Jerry
randomly selecting a Tejano CD and the
without replacing it, randomly selecting
a rap CD from his case?​

Answers

Answer 1

Answer:[tex]\frac{1}{15}[/tex]

Step-by-step explanation:

Given

There are

4 country music CD

1 rock and roll CD

2 rap CD

3 Tejano CD

[tex]\text{Probability that Jerry randomly select a Tejano CD and then a rap CD from his case}=\text{Probability of selecting a Tejano CD}\times \text{Probability of selecting a rap CD}[/tex]

[tex]P=\frac{3}{10}\times \frac{2}{9}[/tex]

[tex]P=\frac{2}{30}[/tex]

[tex]P=\frac{1}{15}[/tex]

3. WEDNESDAY (5/20): The minimum of the graph of a quadratic function is located at (-1,2). The point (2, 2015
also on the parabola. Which function represents this?
a) f(x) = x² + 2x + 3
b) f(x)= x² - 2x+3
c) f(x) = 2x²+4x+4
d) f(x)= 2x²- 4x+4​

Answers

Answer:

C.) f(x) = 2x^2 + 4x + 4

Step-by-step explanation:

The equation of the parabola with vertex (h,k) is y=a(−h+x)^2+k.

Thus, the equation of the parabola is y=a(x+1)^2+2.

To find a, use the fact that the parabola passes through the point (2,20): 20=9a+2.

Solving this equation, we get that a=2.

Thus, the equation of the parabola is y=2(x+1)^2+2.

TO STANDARD FORM

= 2*(x^2+2x+1)+2  

=(2x^2+4x+2)+2  

= 2x^2+4x+2+2  

= 2x^2+4x+4

Find the area of a triangle with a =4, b =6, and c =8.
a. 10.2 units 2
b. 8.4 units 2
C.12.4 units
d. 11.6 units 2

Answers

Answer:

d

Step-by-step explanation:

Given 3 sides of the triangle the area (A) can be calculated using Hero's formula.

A = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]

where s is the semi perimeter of the triangle

s = [tex]\frac{a+b+c}{2}[/tex] = [tex]\frac{4+6+8}{2}[/tex] = [tex]\frac{18}{2}[/tex] = 9 , thus

A = [tex]\sqrt{9(9-4)(9-6)(9-8)}[/tex]

   = [tex]\sqrt{9(5)(3)(1)}[/tex]

   = [tex]\sqrt{135}[/tex]

6-129. Nick represented the equation 3(2x+4)=-6 on the Equation Mat below. Choose a strategy to solve for x. You may continue to use algebra tiles, or you may use symbols on paper.

Answers

Answer:

x = -3

Step-by-step explanation:

You have the following equation:

[tex]3(2x+4)=-6\\[/tex]

you first you distribution property in order to eliminate the parenthesis:

[tex]3*2x+3*4=-6\\\\6x+12=-6[/tex]

next, you subtract 12 in both sides of the equation:

[tex]6x+12-12=-6-12\\\\6x=-18[/tex]

Finally, you divide the equation by 6 and simplify:

[tex]\frac{6x}{6}=-\frac{18}{6}\\\\x=-3[/tex]

hence, the solution to the equation is x = -3

Answer the questions to find the base area of the cone.

Which equation substitutes the given values into the formula for the corresponding variables

Answers

Answer:

The formula is 86=1/3B (6)

The base area is 43.00 square feet

Step-by-step explanation:

V is 86 so that goes in spot, hv to divide 1/3 and hv to find B so last spot is putting in height which is 6. That makes equation

Solving equation

86=(1/3) B(6)

Divide 6 by 1/3

(3/1) 1/3 = 6 (3/1)

86 = 2pi *

Johnny had a math test and he started at 2:18 p.M. It took 75 minutes to complete the test. He had a dentist's appointment at 4:30 p.M. How much time, in minutes, did he have between the end of the test and his appointment time

Answers

Answer:

57 minutes

Step-by-step explanation:

First, add 75 minutes to the time he started the test. Then, subtract the time you get from the time for his dentist appointment.

75 minutes is the same as 1 hour 15 minutes (1 hour = 60 minutes)

  H    M

  2   :  18

+  1   :  15

   3  :  33

He ended the test by 3:33 PM.

 H    M

 4  :  30

- 3  :  33

 0 :  57

Therefore, he had 57 minutes between the end of the test and his appointment.
