Solve for b.
-3b+2.5 = 4
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 = 4Subtract 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

Kevin is rolling two dice together and adding them up. Which sums should come up the most frequently?
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
3 occurs for 2 times
4 occurs for 3 times
5 occurs for 4 times
6 occurs for 5 times
7 occurs for 6 times
8 occurs for 5 times
9 occurs for 4 times
10 occurs for 3 times
11 occurs for 2 times
12 occurs for 1 time.
So, 7 occurs most frequently.

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.
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
[tex]P \to[/tex] Park Crest Middle School
[tex]T \to[/tex] Total
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.
[tex]n = \frac{T}{P}[/tex]
So, we have:
[tex]n = \frac{406240}{400}[/tex]
[tex]n = 1015.6[/tex]
Approximate
[tex]n \approx 1000[/tex]
As a power of 10, we have:

Find m
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

Given f’(x), where is f(x) increasing? Where is f(x) concave up?
Answer:
See explanation below
Step-by-step explanation:
a. f(x) is increasing at (-∞, 1] and [7, ∞) because f'(x) is positive at those intervals.
b. f(x) is concave up at [4, ∞) because the slope of f'(x) or f''(x) is positive.

Hope this helps! have a good day. :)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(x−2)=2(x−3)
(3)(x)+(3)(−2)=(2)(x)+(2)(−3)(Distribute)
3x+−6=2x+−6
3x−6=2x−6
Step 2: Subtract 2x from both sides.
3x−6−2x=2x−6−2x
x−6=−6
Step 3: Add 6 to both sides.
x−6+6=−6+6

In a company there are 33 male and 42 female staff. Calculate the percentage of male and female staffs
Answer: 44%, 56%
Step-by-step explanation:
Given
A company has 33 males and 42 female staff
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
[tex]\Rightarrow \text{Male }\%=\dfrac{33}{75}\times 100\\\\\Rightarrow \text{Male }\%=44\%[/tex]
The percentage of female staff is
[tex]\Rightarrow \text{female }\%=\dfrac{42}{75}\times 100\\\\\Rightarrow \text{female }\%=56\%[/tex]

y - 800,000(1+3)
y - 800,000(0.97)
y = 800,000(1.03)
y=800,000(1-3)
Od
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]
