Answer:
Length is 13
Width is 4
Step-by-step explanation:
Length: 4w-3
Width: w
2L + 2w= P
2(4w - 3) + 2(w)= 34
8w - 6 + 2w= 34
10w - 6= 34
10w = 40
w= 4
Length: 4w-3
4(4) - 3= 13
Width= w

Assume that the car lot contains 20 percent Lincolns, 45 percent Porches, and 35 percent BMWs. Of the Lincol?
I still can't solve the problem. I did it step by step thoroughly but still get the wrong answer. Can someone help? thanks!
Assume that the car lot contains 20 percent Lincolns,
45 percent Porches, and 35 percent BMWs. Of the Lincolns,
70 percent have two airbags, 60 percent of the Porches have
two airbags, and 90 percent of the BMWs have two airbags. Furthermore,
70 percent of the Lincolns, 40 percent of the Porches, and
30 percent of the BMWs are white. The property of being white is
independent from having two airbags. You are assigned a car at random.
If the car has two airbags and is white, what is the probability that it is a Lincoln?
Answer:
0.3261 = 32.61% probability that it is a Lincoln
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this question:
Event A: Has two airbags and is white.
Event B: It is a Lincoln.
Probability of a car having two airbags and being white.
This is:
70%*70% of 20%(Lincolns).
60%*40% of 45%(Porches).
90%*30% of 35%(BMWs). So
[tex]P(A) = 0.7*0.7*0.2 + 0.6*0.4*0.45 + 0.9*0.3*0.35 = 0.3005[/tex]
Probability of a car having two airbags and being white, and being a Lincoln:
70%*70% of 20%(Lincolns).
So
[tex]P(A \cap B) = 0.7*0.7*0.2 = 0.098[/tex]
If the car has two airbags and is white, what is the probability that it is a Lincoln?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.098}{0.3005} = 0.3261[/tex]
0.3261 = 32.61% probability that it is a Lincoln

Find the zeros of the function below.
\small -7x=x^2+12
Answer:
read explanation
Step-by-step explanation:
this is a quadratic equation
first, move the 7x over to the other side so that we have 0 on one side
x^2+7x+12=0
now, we can factor
turn 7x into 3x and 4x, so x^2+3x+4x+12=0
you can turn x^2+3x into x(x+3) and 4x+12 into 4(x+3)
so, our new equation is x(x+3)+4(x+3)=0
that can be turned into (x+4)(x+3)=0 via the distributive property
so, either x+4 or x+3 has to be equal to 0
so, x is either -4 or -3
hope this helped
At Brighton Middle School, Mr. Yule asked 50 randomly selected students from each grade level about their favorite subject, and 12 chose science. He used this data to draw the inference that about 25% of middle school students will indicate science is their favorite subject. If there are 200 students all together, did he make a reasonable inference?
No, Mr. Yule’s sample is biased and too small to be representative of the population.
Yes, Mr. Yule’s sample is small and biased, so it is representative of the population.
No, Mr. Yule’s percentage is too large. He should have used 6%.
Yes, Mr. Yule’s sample is random and representative of the population.
Answer:
D.) "Yes, Mr. Yule’s sample is random and representative of the population."

Find the sum, if it exists, of the infinite geometric series related to the infinite geometric sequence described by An= 18(2)^n-1
Answer:
Step-by-step explanation:
Since r=2 and |r|>1 the sum does not converge to any value. The sum does not exist for this infinite geometric series.
The sum to infinity of the sequence is -18
Sum to infinity of a geometric sequenceThe formula for calculating the sum to infinity of a geometric sequence is expressed as:
Sinfty = a/1-r
where
a is the first term
r is the common ratio
From the nth term
a = 18
r = 2
Substitute
Sinfty = 18/1-2
Sinfty = -18
Hence the sum to infinity of the sequence is -18

Since the probability that the die lands on "4" is 1/6, the probability that it does not land on "4"
is 1 - 1/6.
B:
Since the probability that the die lands in "4" is 1/4, the probability that it does not land on "4"
is 1 - 1/4.
C:
Since the probability that the die lands on "4" is, the probability that it does not land on "4" is

First, calculate the slope (m)
Considering
[tex](x_1,y1) = (12,60)[/tex]
[tex](x_2,y_2) = (15,20)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{20-16}{15-12}[/tex]
[tex]m = \frac{4}{3}[/tex]
Considering:
[tex](x_1,y_1) = (15,20)[/tex]
[tex](x_2,y_2) = (24,y)[/tex]
The slope is:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{y - 20}{24 - 15}[/tex]
[tex]m = \frac{y - 20}{9}[/tex]
Recall that: [tex]m = \frac{4}{3}[/tex]
So:
[tex]\frac{4}{3} = \frac{y - 20}{9}[/tex]
Multiply through by 9
[tex]3*4 = y - 20[/tex]
[tex]y = 20 + 3 * 4[/tex]
[tex]y = 32[/tex]

Find the area of the figure.
Answer:
89
Step-by-step explanation:
So we need to find the area of the triangle. We already know that the individual two triangles height is 6 and so we need to find the width. The top is 13m and we know that 4m+4m is 8. 13-8 would be 5, and 5/2 (because there are two right triangles) is 2.5
After that, we can find 2.5 times 6 would be 15. We don't need to divide by two because we'll just have to multiply again because there are two triangles.
After that, we can find the area of the figure. 8 times 13 would be 104. 104-15 would be 89. That is the area of the figure, 89.
