Answer:
2, 0, -2, -4
Step-by-step explanation:
an = 4 − 2n
a1 = 4 - 2(1) = 2
a2 = 4 - 2(2) = 0
a3 = 4 - 2(3) = -2
a4 = 4 - 2(4) = -4
Answer:
(2, 0, -2, -4)
Step-by-step explanation:
a(1) = 4 - 2(1)
= 4 - 2
= 2
a(2) = 4 - 2(2)
= 4 - 4
= 0
a(3) = 4 - 2(3)
= 4 - 6
= -2
a(4) = 4 - 4(4)
= 4 - 8
= -4
Identify the coordinates of triangle ABC when it is dilated by a scale factor of 2 from the origin (0,0).
Answer:
[tex]A' = (-4,4)[/tex]
[tex]B' = (2,6)[/tex]
[tex]C' = (2,0)[/tex]
Step-by-step explanation:
Given [Missing from the question]
[tex]A = (-2,2)[/tex]
[tex]B= (1,3)[/tex]
[tex]C= (1,0)[/tex]
[tex]k = 2[/tex] --- scale factor
Required
The new coordinates
The new coordinate is calculated by:
[tex]New = Old * k[/tex]
So, we have:
[tex]A' = A * 2[/tex]
[tex]A' = (-2,2) * 2[/tex]
[tex]A' = (-4,4)[/tex]
[tex]B' = B * 2[/tex]
[tex]B' = (1,3) * 2[/tex]
[tex]B' = (2,6)[/tex]
[tex]C' = C * 2[/tex]
[tex]C' = (1,0) * 2[/tex]
[tex]C' = (2,0)[/tex]

Find the value of x and y that will make each quadrilateral a parallelogram.
Answer:
the opposite Angles sum up to give 180
Step-by-step explanation:
3y +3y = 180
y=30
if y = 30 the x = 55
are you clear?
Answer:
3y+3y=180°{sum of opposite angle of parallelogram are supplementary}
6y=80
y=180/6
y=30°
again,
4y-65+x=180°{ sum of of opposite angle of parallelogram are supplementary }
4×30-65+x=108
x=180-55
x=125
so to make quadrilateral as parellogram
3y=3y3×30=3×3090°=90°

A football field measures 300 feet in length. It can also be expressed as approximately
5.7 x 10^n .
If there are 5,280 feet in 1 mile , which is the most reasonable value of n.
Answer: n=-2
Step-by-step explanation:
Given
The length of the football field is [tex]300\ ft[/tex]
In the mile, it can be expressed as [tex]5.7\times 10^n\ mile[/tex]
Also, [tex]5280\ ft=1\ mile[/tex] or
[tex]1\ ft=\dfrac{1}{5280}\ miles\\\\1\ ft=1.893\times 10^{-4}\ miles[/tex]
converting [tex]300\ ft[/tex] to miles
[tex]\Rightarrow 300\times 1.893\times 10^{-4}\\\Rightarrow 5.68\times 10^{-2}\approx 5.7\times 10^{-2}[/tex]
Comparing it with the given value [tex]5.7\times 10^n\ mile[/tex]
we get [tex]n=-2[/tex]
Dionne can fold 175 packing boxes in 50 minutes. Elias can fold 120 packing boxes in 40 minutes. Use unit rates to find how much time it will take each person to fold 210 packing boxes. Drag the numbers to explain and show your answer. Numbers may be used once or not at all.
Answer:
Dionne can fold 210 packing boxes in 60 minutes
Elia can fold 210 packing boxes in 70 minutes
Step-by-step explanation:
Dionne:
175 packing boxes in 50 minutes
Boxes folded per minute = Total packing boxes / number of minutes
= 175/50
= 3.5 packing boxes per minute
Number of minutes to fold 210 packing boxes = Total packing boxes / boxes packed per minute
= 210/3.5
= 60 minutes
Dionne can fold 210 packing boxes in 60 minutes
Elias:
120 packing boxes in 40 minutes
Boxes folded per minute = Total packing boxes / number of minutes
= 120/40
= 3 packing boxes per minute
Number of minutes to fold 210 packing boxes = Total packing boxes / boxes packed per minute
= 210/3
= 70 minutes
Elia can fold 210 packing boxes in 70 minutes

If t varies inversely as a and t= 2 when a = -4, what is t when a = 1/3?
1. -2 2/3
2. -24
3. - 1/6
4. -2/3
Answer:
t = - 24
Step-by-step explanation:
Given t varies inversely as a then the equation relating them is
t = [tex]\frac{k}{a}[/tex] ← k is the constant of variation
To find k use the condition t = 2 when a = - 4
2 = [tex]\frac{k}{-4}[/tex] ( multiply both sides by - 4 )
- 8 = k
t = [tex]\frac{-8}{a}[/tex] ← equation of variation
When a = [tex]\frac{1}{3}[/tex] , then
t = [tex]\frac{-8}{\frac{1}{3} }[/tex] = - 24

4/5 or 0.8 or 80%
hope you have an amazing day <3
The probability that the pitcher will throw 4 or fewer pitches to a batter is 0.9.
What is Probability ?The way to find the likeliness of an event is called Probability.
It is given that
Pitcher is throwing ball
The probability that he throws 4 or fewer pitches to a batter is = ?
The no. of favourable outcomes for the given condition is
P(X ≤4 ) = P(X=1) + P(X =2) + P(X=3)+P(X=4)
Total Outcomes = 15+20+40+15+20
Total outcomes = 100
Favourable outcomes = 15+20+40+15
Favourable Outcomes = 90
Probability = Favourable Outcomes / Total Outcomes \
Probability = 90/100 = 0.9
Therefore the probability that the pitcher will throw 4 or fewer pitches to a batter is 0.9.

4,12,20 find the 41st term
Answer:
The 41st term of the given series is 324
Step-by-step explanation:
a= 4
a2= 12
d= a2-a
d= 12-4 = 8
now, we have to find 41 term that is a41
a41 = a+ 40d
a41= 4+ 40× 8
a41= 4+ 320
= 324
therefore the 41st term is 324
Answer:
324
Step-by-step explanation:
The sequence observed appears to be an arithmetic sequence. The formula for an arithmetic sequence is an = a1 + (n - 1)d, where an is the nth term, a1 is the first term, n is the term position, and d is the common difference. Let's write down what we know.
n = 41
a1 = 4
d = 8
So, let's plug our values into the equation and solve.
an = 4 + (41 - 1)8
an = 4 + (40)8
an = 4 + 320
an = 324

Kat is interested in getting chickens so she can have fresh eggs. Before she buys her chickens, she wants to find the mean number of eggs each one will lay. She begins by randomly selecting 40 chickens from a large poultry farm and counts how many eggs each one lays within one month. She finds the mean to be 24.8 eggs with a standard deviation of 6.9 eggs. Which of the following is the 90% confidence interval for the true mean number of eggs chickens from this poultry farm lay in one month?
Find the t-table here.
(21.85, 27.75)

The confidence interval of eggs chickens from this poultry farm lay in one month will be (22.96, 26.64). Then the correct option is C.
What is the confidence interval of the sample?If the sample size is given to be n < 30, then for finding the confidence interval for mean of population from this small sample, we use t-statistic.
Let the sample mean given as μ and
The sample standard deviation σ, and
The sample size = n, and
Then the heights would be outside the 90% confidence interval will be
For 90% confidence interval, we have z = 1.645
⇒ μ ± z (σ/√n)

Bubble algae cells can grow up to 5 cm in diameter. Calculate the surface area : volume ratio of this cell.
Answer:
6:5
Step-by-step explanation:
Bubble algae cells can grow up to 5 cm in diameter. Calculate the surface area : volume ratio of this cell.
The algae is spherical in nature
Volume of the algae =4/3 pi r³
Volume of the algae = 4/3×pi×2.5³
Volume of the algae = 62.5/3 pi
Surface area = 4pi r²
Surface area = 4pi ×2.5²
Surface area = 25pi
Taking their ratio
surface area : volume ratio
= 25pi:62.5/3 pi
= 25 × 3/62.5
= 1.2
Hence the required ratio is 12/10 which is 6:5
A circle has a circumference whose length is 25(pi). Find the length of an arc whose central angle is 120.
9514 1404 393
Answer:
(25/3)π
Step-by-step explanation:
A central angle of 120° is 1/3 of a circle, so the arc length will be 1/3 of the circumference:
(1/3)(25π) = (25/3)π ≈ 26.18 . . . . units
Answer:
Solution :-Circumference = 25π
Total angle made by circle = 360
Now,
120 is ⅓ of 360⁰.
⅓ × 25π = 25π/3
Hence,
Length of arc = 25π/3
