Kevin is rolling two dice together and adding them up. Which sums should come up the most frequently?

Answers

Answer:

7 occurs most frequently.

Step-by-step explanation:

If we roll two dice, we do get sample space as

(1,1) = 1+1 =2        (4,1)=4+1=5

(1,2)= 1+2 =3        (4,2)= 34+2=6

(1,3)= 1+3=4         (4,3)= 4+3=7

(1,4)=1+4=5          (4,4)= 4+4=8

(1,5)=1+5=6          (4,5)= 4+5 =9

(1,6)=1+6=7           (4,6)= 4+6=10

(2,1)= 2+1=3          (5,1)= 5+1=6

(2,2)=2+2=4         (5,2)=5+2 =7

(2,3)= 2+3=5        (5,3) =5+3=8

(2,4)=2+4=6         (5,4) =5+4 =9

(2,5)=2+5=7          (5,5)=5+5=10

(2,6)=2+6=8          (5,6)=5+6=11

(3,1)=3+1=4            (6,1)= 6+1=7

(3,2)=3+2=5          (6,2)=6+2=8

(3,3)=3+3=6           (6,3)=6+3=9

(3,4)=3+4=7           (6,4) =6+4 =10  

(3,5) =3+5=8          (6,5)=6+5=11

(3,6)=3+6=9            (6,6)=6+6=12

2 occurs for 1 time

Solve for b.
-3b+2.5 = 4

Answers

Answer:

b = −0.5

Step-by-step explanation:

Let's solve your equation step-by-step.

−3b+2.5=4

Step 1: Subtract 2.5 from both sides.

−3b+2.5−2.5=4−2.5

−3b=1.5

Step 2: Divide both sides by -3.

-3b/-3 = 1.5/-3

The value of 'b' in the equation given is -0.5

Given the expression for which we could solve for the unknown:

-3b + 2.5 = 4

Subtract 2.5 from both sides

-3b = 4 - 2.5

-3b = 1.5

divide both sides by -3 to isolate b

-3b/-3 = 1.5/-3

b = -0.5

Therefore, the value of b in the equation given is -0.5

Answer:

D. 70.53

Step-by-step explanation:

To solve this problem, one must use the right angle trigonometric rations. These ratios can be used to describe the ratio between the sides and an angle in a right triangle. Please note, each side is named relative to the angle that one is looking at, thus the same side can acquire different names based on the angle one uses to describe it. The trigonometric ratios are the following:

[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]

In this case, one is asked to find the measure of (<CBA), one is given the hypotenuse (the side opposite the right angle), and the side adjacent to this angle. Therefore, one should use the cosine (cos) function to find this angle.

[tex]cos(\theta)=\frac{adjacent}{hypotenuse}[/tex]

Substitute,

[tex]cos(CBA) = \frac{3}{9}[/tex]

Simplify

[tex]cos(CBA) = \frac{1}{3}[/tex]

Inverse operations,

[tex]CBA=cos^-1(\frac{1}{3})[/tex]

Compute,

m<CBA = 70.53

Od

Answers

Answer:

y = 800,000[1.03]

Step-by-step explanation:

Given:

Number of people attend 2012 country fair = 800,000

Attendance increases = 3% per year

Find:

Function represents attendance  after 2012

Computation:

A = P[1+r]ⁿ

Assume;

Number of people attend country fair after 2012 = y

So,

y = 800,000[1+3%]¹

y = 800,000[1+0.03]

y = 800,000[1.03]

Function represents attendance  after 2012 is y = 800,000[1.03]

At a location 30m from the base of a flagpole, the angle of elevation is 34 degrees. Determine the height of the flagpole to the nearest meter.

Answers

Answer:

20.2 m

Step-by-step explanation:

At a location 30m from the base of a flagpole, the angle of elevation is 34 degrees. Determine the height of the flagpole to the nearest meter.

We solve this question using the Trigonometric function of Tangent

tan θ = Opposite/Adjacent

θ = 34°

Adjacent =30m

Opposite = Height of the flag pole = x

Hence

tan 34 = x/30

Cross Multiply

tan 34 × 30m

= 20.235255505 m

Approximately = 20.2 m

Hence, the height of the flag pole to the nearest meter = 20.2m

Step-by-step explanation:

Given

Let

So, we have:

[tex]P = 400[/tex]

[tex]T = 406240[/tex]

Required

Determine the number of times T is greater than P

This is calculated by dividing T by P.

i.e.

So, the total staff is the sum of male and female

[tex]\Rightarrow \text{Total=}33+42\\\Rightarrow \text{Total=}75[/tex]

The percentage of male staff is
