X - 27
The coefficient is a number used to multiply a variable. The variable is x. The coefficient is : (understood but not written)...it is 1.
ur problem is actually 1x - 27.....however, the 1 is not usually written.
The answer is 298
Two tires is 70-sold for 130
3 rims is 225- sold for 408
Headlights is 20-sold for 75
Add the totals of what they cost to buy, then add the total of money she got from everything which is 315 and then the total for the amount of money she got for selling them which is 613 sooooo do 613-315 ☺️
Answer: 11x
---------------------------------------------------
---------------------------------------------------
Explanation:
Let L be the length of rectangle B
There are two copies of L (along the top and bottom of the rectangle). The vertical pairs of sides are both 7x each.
For the triangle, we have three sides of 12x since this is an equilateral triangle. All three sides are congruent for any equilateral triangle.
The perimeter of the triangle is
P = s1+s2+s3
P = 12x+12x+12x
P = 36x
The perimeter of the rectangle is
P = 2*L+2*W
P = 2L+2*7x
P = 2L+14x
Since both perimeters are the same, this means
perimeter of triangle = perimeter of rectangle
36x = 2L+14x
36x-14x = 2L+14x-14x
22x = 2L
2L = 22x
2L/2 = 22x/2
L = 11x
So the length of the rectangle, in terms of x, is 11x. This is the final answer.
Note: if we knew the value of x, then we could find the numeric value of the length for the rectangle. But since we don't know x, we leave it as 11x.
Answer:
Confidence interval @ 90% = [0.5324 < p < 0.5656]
Step-by-step explanation:
We are given the following information:
Sample size (n) = 2430
Proportion of win (p) = 0.549
Proportion of loss (q) => 1-p = 0.451
By formula of confidence interval,
CI = p ± Z(90%) * 
,
CI = 0.549±(1.645* ((0.549*(0.451))/2430))^(0.5)
CI = [0.5324 < p < 0.5656]
