A store sold a total of 21,650 balls. It sold 11,795 baseballs. It sold 4,150 fewer basketballs than baseballs. The rest of the balls sold were footballs. How many footballs did the store sell?
Answer:
2210
Step-by-step explanation:
Given that a store sold a total of 21,650 balls.
No of baseballs sold =11795
There were baseballs, basketballs and footballs in the store
No of basketballs sold = 4150 fewer than baseballs = [tex]11795-4150\\=7645[/tex]
Total sales = [tex]21650[/tex]
Baseballs sold = [tex]11795\\[/tex]
Basketballs sold =[tex]7645[/tex]
No of footballs sold = [tex]21650-11795-7645\\=2210[/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.
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.
What is the equation of the line that is parallel to the given line and passes through the point (–2, 2)?
y = x + 4
y = x +
y = –5x + 4
y = –5x +
we know that
If two lines are parallel, then their slopes are the same
Step 1
Find the slope of the given line
we know that
the formula to calculate the slope between two points is equal to
[tex]m=\frac{(y2-y1)}{(x2-x1)}[/tex]
in this problem we have
[tex](x1,y1)=(-5,-4)\\(x2,y2)=(0,-3)[/tex]
substitute in the formula
[tex]m=\frac{(-3+4)}{(0+5)}[/tex]
[tex]m=\frac{(1)}{(5)}[/tex]
[tex]m=\frac{1}{5}[/tex]
Step 2
Find the equation of the line
we know that
the equation of the line into point-slope form is equal to
[tex]y-y1=m(x-x1)[/tex]
we have
[tex]m=\frac{1}{5}[/tex]
[tex](x1,y1)=(-2,2)[/tex]
substitute
[tex]y-2=\frac{1}{5}(x+2)[/tex]
[tex]y=\frac{1}{5}x+\frac{2}{5}+2[/tex]
[tex]y=\frac{1}{5}x+\frac{12}{5}[/tex]
therefore
the answer is
[tex]y=\frac{1}{5}x+\frac{12}{5}[/tex]

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]
Hence, the average speed of ying zyiyu is [tex]46.15\;\rm{mph}[/tex].

Find the probability of getting exactly 6 girls in 8 births.
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]

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.

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]

Alex wants to start an IRA that will have $1,250,675 in it when he retires in 30 years. How much should he invest semiannually in his IRA to do this if the interest is 4.5% compounded semiannually? Assume an Annuity Due. Round to the nearest cent.
Answer:
$9828.44
Step-by-step explanation:
The semi annual payment is such that the future value of the annuity due is equal to the desired amount when he retires.
The formula to calculate future value of an annuity due periodic payment of M for time period T for given periodic return r,
A=[tex]\frac{M(1+r)^{T+1}-(1+r)}{r}[/tex]
in this question there are 30*2= 60 payments and the semi annual rate= 4.5/2= 2.25%
putting values we get
1250675= [tex]\frac{M(1+2.25%)^{60+1}-(1+2.25%)}{2.25%}[/tex]
on solving we get M= $9828.44
Alex needs to invest $9828.44 semiannually in his IRA
