5
Answer:
5b+3-b-b-4
Explanation:
First, you’ll do 5b-b-b which will become 5b-2b and equals 3b. Then 3-4 equals -1.
When simplified, you get 3b-1
Dartboard is a circular board marked with numbered segments used as a target in the game of darts. Sara can score 24 with 6 darts which all hits the target.

Dartboard</h3>
Dartboard is a circular board marked with numbered segments used as a target in the game of darts.
In a dartboard there are 4 different types of scoring,
- Bull's eye- When the dart hits the center of the dartboard with 9 points.
- 2nd circle- When the dart hits the second circle with 7 points.
- 3rd circle-When the dart hits the third circle with 5 points.
- Outer circle- When the dart hits the last circle of the dartboard with 1 points.
If all the dart hit the target the score must be equal to or more than 6 and less than or equal to the 54. Thus the option 1 and 4 is incorrect. 29 and 31 also can be eliminates as the sum of the odd number must be even.
Thus Sara can score 24 with 6 darts which all hits the target.

<h2>
Answer with explanation:</h2>
Given : Sample size 
Sample mean : 
Sample standard deviation : 
Let 
be the population mean of "like" ratings of male dates made by the female dates.
As per question ,
Null hypothesis : 
Alternative hypothesis : 
, It means the test is a one-tailed t-test. ( we use t-test when population standard deviation is unknown.)
Test statistic:
For 0.05 significance and df =188 (df=n-1) p-value = .001582. [By t-table]
Since .001582< 0.05
Decision: p-value < significance level , that means there is statistical significance, so we reject the null hypothesis.
Conclusion : We support the claim at 5% significance that t the population mean of such ratings is less than 8.00.
Answer:
- C) (x − 3)2 = 25
- C) Factor out 4 from 4x2 + 40x.
Step-by-step explanation:
1. Adding the square of half the x-coefficient to both sides of the equation will "complete the square." That square is 9, so the result on the right is 16+9 = 25. Only selection C matches.
___
2. To complete the square, you want to be able to put the quadratic into the form a(x -h)^2 = -k. For the purpose, it is most convenient to first factor "a" from the given quadratic. Then you can determine "-h" to be half the x-coefficient inside the parentheses.
Here, that looks like ...
4(x² +10x) = 80 . . . . . . . . . . step 1: factor out 4
4(x² +10x +25) = 180 . . . . . add 25 inside parentheses and the same number (4·25) on the right side of the equation
4(x +5)² = 180 . . . . . . . . . . . written as a square
