250
4. Express the ratio as a percent:
%
Answers
650 / 250 = 13 / 3 = 2.6 = 260%
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]
what is the unknown factor 9Xp= 45
Answers
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.

Find the probability of getting exactly 6 girls in 8 births.
Answers
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]
Thus, the probability of having exactly [tex]6[/tex] girls in [tex]8[/tex] birth is [tex]\boxed{\bf 0.10937}[/tex].

Keywords: Probability, exact event, sample space, number of element, complement event, success, failure, favorable, trial, P(E)=n(E)/n(S), P(A')=1-P(A).
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.

I really need explanation for this Mean Value Theorem. Thanks
Answers
the mean value theorem states, that the function for such value to exist, must be continuous and differentiable, graph wise, that means the graph of the function between those bounds, must be "a smooth line", without any abrupt jumps or changes like a spike or a sharp sink.
so, rewording the material some, the piece-wise function has 3 subfunctions, and within the interval of [0, 2], those 3 must meet seamlessly at the junction points, namely 0 and 1, so the "4" part must seamlessly blend in with the ax + b part at 0, and the ax + b part must meet seamlessly with the x²+5x+c.
that said, we could simply freely pick a "c" value for the third subfunction, and from there, make the second subfunction to meet it at that point, so let's do so.
let's say, we pick c = 3, so the 3rd subfunction is x² + 5x + 3.
now, what's f(x) for that parabola at x = 1?, well, is 1²+5(1)+3, or 9, so it lands on the ( 1, 9 ) point then.
now, the "4" subfunction is just a horizontal line, well, at x = 0, is really just a dot, so, ax + b must meet that dot and also must meet the parabola at (1, 9), given that c = 3.
so, now, what's the equation of a line that passes through (0, 4) and (1, 9)?
[tex]\bf \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ 0}}\quad ,&{{ 4}})\quad % (c,d) &({{ 1}}\quad ,&{{ 9}}) \end{array} \\\\\\ % slope = m slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{9-4}{1-0}\implies 5 \\\\\\ % point-slope intercept \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-4=5(x-0)\implies \boxed{y=5x+4}[/tex]
so, that'd be the 2nd subfunction, meeting "4" and x² + 5x + 3, and surely you can see what "a" and "b" are.
check the picture below.
and since they meet seamlessly, they meet the mean value theorem at [0, 2].

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.
Answers
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.

If ying zyiyu covered the first 200 miles of a trip going at 50 mph and the last hundred miles going at 40 mph, what was his average speed for the entire trip? Teacher told me it is not 45
Answers
To find the total time we need to do some division.
Time for 200 miles=200/50=4 hours.
Time for 100=100/40=5/2 hours.
Total time=13/2 hours. Total distance=200+100=300 miles.
Av speed=300/(13/2)=300×2/13=600/13=46.15 mph approx.
The average speed of ying zyiyu is [tex]46.15\;\rm{mph}[/tex]
Average speed is the ratio of the total distance traveled by a body to the total time taken by the body to cover the total distance.
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]
