A line passes through the point (-8,5) and has a slope of 3/2
Write an equation in slope-intercept form for this line.
To write the equation for this line in slope-intercept form, substitute the given values into the formula and solve for the y-intercept.
Explanation:To write an equation in slope-intercept form, we need to use the formula y = mx + b, where m is the slope and b is the y-intercept.
Given that the line passes through the point (-8,5) and has a slope of 3/2, we can substitute these values into the equation.
So, the equation of the line in slope-intercept form is y = (3/2)x + b. To find the y-intercept, we substitute the coordinates of the point (-8,5) into the equation and solve for b.
5 = (3/2)(-8) + b
5 = -12 + b
b = 17
Therefore, the equation in slope-intercept form is y = (3/2)x + 17.

(d) estimate p(x < 1.5), i.e., the proportion of all thickness values less than 1.5. [hint: if you knew the values of μ and σ, you could calculate this probability. these values are not available, but they can be estimated.] (round your answer to four decimal places.)
To estimate p(x < 1.5), we can use the concept of probability. Given the information provided, we can assume a uniform distribution between 1.5 and 4. The shaded area in Figure 5.20 represents the shortest 30 percent of repair times. Therefore, we can estimate that p(x < 1.5) is approximately 0.30.
Explanation:To estimate p(x < 1.5), we can use the concept of probability. Given the information provided, we can assume a uniform distribution between 1.5 and 4. The shaded area in Figure 5.20 represents the shortest 30 percent of repair times. Since we want to estimate the proportion of values less than 1.5, we can estimate it as the shaded area to the left of 1.5. This shaded area is equivalent to the shortest 30 percent of repair times, which is 0.30. Therefore, we can estimate that p(x < 1.5) is approximately 0.30.

The actual probability is 0.159
To estimate the probability P(X < 1.5) without knowing the exact values of the mean (μ) and standard deviation (σ), we can use the empirical rule (also known as the 68-95-99.7 rule). This rule states that for a normally distributed variable:
Approximately 68% of the data falls within 1 standard deviation (σ) of the mean (μ).
Approximately 95% of the data falls within 2 standard deviations (2σ) of the mean.
Approximately 99.7% of the data falls within 3 standard deviations (3σ) of the mean.
Since the exact values of μ and σ are not available, we can estimate them using the sample mean (X) and sample standard deviation (s) of the data.
In this case, let's assume we have a sample of thickness values {x1, x2, ..., xn}. The sample mean (X) is the average of all the sample values:
X = (∑xi) / n
The sample standard deviation (s) is the square root of the variance (s^2), which is the average of the squared deviations from the mean:
s^2 = ∑(xi - X)^2 / n
Once you have the estimated values of μ (approximately equal to X) and σ (approximately equal to s), you can use the empirical rule to estimate P(X < 1.5).
For example, if you estimate that μ = 2 and σ = 0.5, then:
P(X < 1.5) = P(X < μ - σ) ≈ P(X < 2 - 0.5) ≈ P(X < 1.5) ≈ 0.159
Remember that this is just an estimate, and the actual probability may be slightly different.

Original Amount
2. Substitute the known quantities for the amount of the increase and the original amount.
Percent Increase =
900 − 250
250
3. Subtract.
Percent Increase =
650
250
4. Express the ratio as a percent:
%
Answer:
260 %
Step-by-step explanation:
1) Since, the percentage formula is,
[tex]\text{Percent Increase}=\frac{\text{Amount of Increase}}{\text{Original Amount}}[/tex]
2) Given,
Original amount = 250,
New amount = 900
So, the amount of increase = New amount - Original amount = 900 - 250 = 650
By substituting the values,
[tex]\text{Percentage increase}=\frac{650}{250}[/tex]
3) Now, for expressing the ratio into percentage we need to multiply by 100,
[tex]\frac{650}{250}\times 100=\frac{65000}{250}= 260\%[/tex]

A rectangular field is 0.4 kilometers long and 0.3 kilometers wide. What is the area of the field in square meters?
The area of the rectangular field is 120,000 square meters.
How do we find the area of the rectangular field?We shall multiply the length by its width, to find the area of the rectangular field.
We can calculate like this:
Area = Length x Width
Area = 0.4 kilometers x 0.3 kilometers
Next, we convert the measurements to square meters, recalling that 1 kilometer = 1000 meters:
Area = (0.4 km * 1000 m/km) x (0.3 km * 1000 m/km)
Area = (400 m) x (300 m)
Then, multiplying the values, we have:
Area = 120,000 square meters
Hence, the area of the rectangular field is 120,000 square meters.

The probability of having exactly [tex]6[/tex] girls in [tex]8[/tex] birth is [tex]\boxed{\bf 0.10937}[/tex].
Further explanation:
Concept used:
The probability of an event [tex]E[/tex] is calculated as follows:
[tex]\boxed{P(E)=\dfrac{n(E)}{n(S)}}[/tex]
Here, [tex]n(E)[/tex] is the number of favorable outcomes in an event [tex]E[/tex] and [tex]n(S)[/tex] is the number of element in sample space [tex]S[/tex].
The probability of exactly [tex]r[/tex] success in [tex]n[/tex] trial is expressed as follows:
[tex]\boxed{P(F)=^{n}C_{r}p^{r}q^{n-r}}[/tex]
Here, [tex]r[/tex] is the probability of success in an event and [tex]q[/tex] is the probability of failure.
Calculation:
Consider [tex]A[/tex] as an event of having a girl in first birth and [tex]P(A)[/tex] as the probability of event [tex]A[/tex].
The probability of having a girl is [tex]P(A)=\frac{1}{2}[/tex].
Assume that [tex]A'[/tex] is the complement event of an event [tex]A[/tex] and [tex]P(A')[/tex] is the probability of complementary event [tex]A'[/tex].
The event is the event of not having a girl in the first birth.
The probability of event [tex]A'[/tex] is calculated as follows:
[tex]\boxed{P(A')=1-P(A)}[/tex] …… (1)
Substitute [tex]P(A)=\frac{1}{2}[/tex] in the equation (1) to obtain the probability of event [tex]A'[/tex].
[tex]\begin{aligned}P(A')&=1-\dfrac{1}{2}\\&=\dfrac{1}{2}\end{aligned}[/tex]
The probability of having exactly [tex]6[/tex] girls in [tex]8[/tex] birth is calculated as follows:
[tex]\begin{aligned}P(F&)=^{8}C_{6}\left(\dfrac{1}{2}\right)^{6}\left(\dfrac{1}{2}\right)^{8-6}\\&=\dfrac{8!}{6!\cdot 2!}\cdot (0.5)^{6}\cdot (0.5)^{2}\\&=28(0.5)^{8}\\&=0.10937\end{aligned}[/tex]

Final answer:
To find the probability of getting exactly 6 girls in 8 births, we use the binomial probability formula. In this case, the probability is approximately 0.01.
Explanation:
To find the probability of getting exactly 6 girls in 8 births, we can use the binomial probability formula:
P(x = 6) = C(n, x) * pˣ * (1-p)(n-x)
Where:
C(n, x) is the binomial coefficient, which represents the number of ways to choose x objects from a set of n objects.p is the probability of success (in this case, the probability of having a girl) in a single trial. n is the number of trials (in this case, the number of births).x is the desired number of successes (in this case, the desired number of girls).In this particular case, P(x = 6) = C(8, 6) * (0.5)⁶ * (0.5)(8-6) = 28 * 0.015625 * 0.015625 = 0.009765625, or approximately 0.01.

Here, ying zyiyu covered the first [tex]200\;\rm miles[/tex] of the trip at [tex]50\;\rm mph[/tex] so,
Total time taken by ying zyiyu to cover [tex]200\;\rm miles[/tex] is calculated as-
[tex]t_1=\dfrac{200}{50}\\t_1=4\;\rm hour[/tex]
Similarly, ying zyiyu covered the first [tex]100\;\rm miles[/tex] of the trip at [tex]40\;\rm mph[/tex] so,
Total time taken by ying zyiyu to cover [tex]100\;\rm miles[/tex] is calculated as-
[tex]t_2=\dfrac{100}{40}\\t_2=2.5\;\rm hour[/tex]
So, the total time taken by ying zyiyu to travel [tex]300\;\rm miles[/tex] is [tex]4+2.5=6.5\;\rm hours[/tex]
Now, the average spped is calculated as-
[tex]\rm{Average\;Speed}=\dfrac{Total\;Distance}{Total\;Time}\\\rm{Average\;Speed}=\dfrac{300}{6.5}\\\rm{Average\;Speed}=46.15\;\rm mph[/tex]

what is the unknown factor 9Xp= 45
To find the unknown factor in the equation 9Xp = 45, divide both sides by 9 to isolate X, resulting in Xp = 5. Therefore, the value of X is 5 when multiplied by the variable p.
To solve the equation 9Xp = 45, we need to find the value of an unknown variable X. The equation indicates that 9 times some number X equals 45. By dividing both sides of the equation by 9, we can isolate X to find its value.
Step 1: Write down the equation: 9Xp = 45.
Step 2: Divide both sides by 9: Xp = 45 ÷ 9.
Step 3: Simplify the right side: Xp = 5.
Therefore, the value of the variable X that makes the equation true when multiplied by p is 5.
