Answer:
Area: 2206.86 square m
Perimeter: 194.25 m
Step-by-step explanation:
Area:
30 x 50 = 1500 square m
30/2 = 15 = the radius of the semi circles
pi x 15^2 = 706.86 square m
1500 + 706.86 = 2206.86 square m
Perimeter:
pi x 15 x 2 = 94.25 m
94.25 (perimeter of both semi circles) + (50 x 2) = 194.25 m

Answer:
Pretty sure 4.1 is an even number, 88° to be exact.
since your homework is quite much and kinda boring, the only thing you could offer me as motivation are brainliests. like in reposting the same sheet.
but this here for free: the of all three angles inside a triangle is 180 degrees.
half a turn of a full circle is 180 degrees, wich is important to calculate excercises 2 and 3 using subtraction.
for the first brainliest you can have 1-4
for the second 5-7 and for the third and fourth 8-9 and 10-11.
the whole sheet for a maybe-brainliest just isn't enough. it's like half an hour of grind work man

When Zoe was six-year-old Lulu is twice her age Zoe is 10 years old now how old is Lulu
Answer: 20 years old
Step-by-step explanation: when Zoe was six years old, Lulu would have been 12 years old since Lulu's age is twice that of Zoe's. Since Zoe is now 10 years old, Lulu would have to be 20 years old since 10 multiplied by 2 equals 20.

You roll a die 42 times. The table shows the results. Find the experimental probability of rolling each number. Write each probability as a fraction in simplest form. For which number is the experimental probability of rolling the number the same as the theoretical probability?
p(one)=
p(two)=
p(three)=
p(four)=
p(five)=
p(six)=
no links, please
There are 6 numbers in a die.
So, theoretical probability of each no. = 1/6
P(1) = 7/42 = 1/6
P(2)= 6/42 =1/7
P(3) = 14/42= 1/3
P(4)= 4/42=2/21
P(5)= 6/42= 1/7
P(6)= 5/42
For no. 1 experimental probability of rolling the number the same as the theoretical probability

the chocolate bar did Sarah and her two friends
each get?
Answer:
1/15 each
Step-by-step explanation:
1/5 of chocolate is separated into 3
1/5 divided by 3 = 1/5 x 1/3 = 1/15 of the whole bar

O Linear association
O Non-Linear association
No association
Answer:
Step-by-step explanation:
I'm assuming that non-linear means that there is some type of association between the dots, they are just not in a straight line. Now, they definitely are NOT in a straight line, but they do appear to be falling in an exponential pattern. I would say that this is a non-liner association (exponential decay, to be specific).

Step-by-step explanation:
Chen is playing a game that requires each player to spin an arrow to one of four colors, equally divided: green, orange, purple, or yellow.
Four players before Chen spun the arrow to purple, but Chen really wants her arrow to land on green. How is the probability of Chen’s spin affected by the spins of previous players?
Chen's probability of landing on purple is increased because the previous players all landed on green.
Chen's chances of landing on purple are not affected by the other players landing on green.
Chen's probability of landing on purple is decreased because the previous players all landed on green.
Answer:
1/4
Step-by-step explanation:
They are equally divided and there are a total 4 sections.
To find probability for yellow:
Numerator : how many yellows sections there are
Denominator : total sections there are
Therefore, the probability would be 1 in 4 chances.

it's the 3 one

Show the relationship between the number of weeks and Mike's savings using an equation.
Type your answer starting with either "W=" or "S=".
Answer: S = 50W + 75
Step-by-step explanation:
I got to this answer by a bit of trial and error.
I first noticed that the relationship between the balance in the savings account from week to week was increasing by 50.
But when I tried W = S + 50, that did not work at all because when I plug in 125 for S, I should get 1 for W, but instead I get 175. So I realized I had something backwards.
I then tried listing the relationship as ordered pairs of (W, S).
For example I did (1, 125), (2, 175), (3, 275) and so on. So I thought of S like y and W like x where S is a function of W. I used the equation y = mx +b or S=mW + b as an outline. I figured that W would have to be multiplied by 50 to get that jump between the numbers in the S column. But I could not do S=50W + 125 because if W = 1, S = 175 when S should equal 125. So I subtracted 50 from the 125 and got 75. So my final equation was S=50W+75. If you test it with the ordered pairs listed above, you will see that the equation checks out. Try it yourself! I hope this was helpful in some way. Good luck!
For the following geometric sequence find the explicit formula.
{12, -6, 3, ...}
Answer:
Tn = 12(-1/2)^n
Step-by-step explanation:
We have the nth term of a geometric sequence as
Tn = ar^n-1
a is the first term
r is the common ratio
n is term number
by dividing the second term by the first, we can have the common ratio
We have this as -6/12 or 3/-6 = -1/2
a the first term is 12
So we have the explicit formula as;
Tn = 12(-1/2)^n

Use the binomial expression (p+q)^n to calculate a binomial distribution with n=5 and p=0.3.(Show all steps)
Answer:
The binomial in expanded form is [tex](0.3 + q)^{5} = \frac{243}{100000} + \frac{81}{2000}\cdot q + \frac{27}{100}\cdot q^{2} + \frac{9}{10} \cdot q^{3} + \frac{3}{2}\cdot q^{4} + q^{5}[/tex].
Step-by-step explanation:
The Binomial Theorem states that a binomial of the form [tex](a + b)^{n}[/tex] can be expanded by using the following identity:
[tex](a + b)^{n} = \Sigma \limits^{n}_{k = 0}\,\frac{n!}{k!\cdot (n-k)!}\cdot a^{n-k}\cdot b^{k}[/tex] (1)
If we know that [tex]a = p = 0.3[/tex] and [tex]n = 5[/tex], then the expanded form of the binomial is:
[tex](p+q)^{n} = \frac{243}{100000} + 5\cdot \left(\frac{81}{10000} \right)\cdot q + 10\cdot \left(\frac{27}{1000})\cdot q^{2} + 10\cdot \left(\frac{9}{100} \right)\cdot q^{3} + 5\cdot \left(\frac{3}{10} \right)\cdot q^{4} + q^{5}[/tex]
[tex](0.3 + q)^{5} = \frac{243}{100000} + \frac{81}{2000}\cdot q + \frac{27}{100}\cdot q^{2} + \frac{9}{10} \cdot q^{3} + \frac{3}{2}\cdot q^{4} + q^{5}[/tex]

Answer:
3x³ + x² + x + 1
= 3x³ - 3x² + 4x² - 4x + 5x - 5 + 6
= 3x²(x - 1) + 4x(x - 1) + 5(x - 1) + 6
= (x - 1)(3x² + 4x + 5) + 6
but 3x³ + x² + x + 1 = (x - 1).Q(x) + R
=> Q(x) = 3x² + 4x + 5
R = 6

Answer:
14
Step-by-step explanation:
a2+(48)2=
502\,\,50^{2}502
Use the Pythagorean Theorem.
a2+2304=a^{2}+2304=a2+2304=
2500\,\,25002500
Simplify.
−2304-2304\phantom{=}−2304=
−2304\,\,-2304−2304
Subtract 2304 from both sides.
a2=a^{2}=a2=
196\,\,196196
a2=\sqrt{a^{2}}=a2
=
±196\,\,\pm\sqrt{196}±196
Square root both sides.
a=a=a=
14\,\,1414
Simplify. Ignore negative root, as length must be positive.

Tillmon is the point guard for his basketball team. out of 63 attempts, tillmon scores 33 times.
Based on this information, what is his probability of scoring on his next shot?
A 1/2
B 10/21
C 11/21
D 3/6
Answer:
C. 11/21
Step-by-step explanation:
Find the probability that he scores in general, by dividing 33 by 63:
33/63
Simplify this by dividing the numerator and denominator by 3:
= 11/21
So, the probability that he will score his next shot is 11/21
The correct answer is C. 11/21
Triangle ABC is going to be reflected over the y-axis.
If A is located at (4,3), where will A' be located?
Answer:
(-4, 3)
Step-by-step explanation:
There are coordinate rules for reflection that really help me with these:
Reflection over x-axis -- (x, y) -> (x, -y)
Reflection over y-axis -- (x, y) -> (-x, y)
Reflection over y = x -- (x, y) -> (y, x)
Reflection over y = -x -- (x, y) -> (-y, -x)

HELP!! Am lost with this and is due pretty soon!
Answer:
∠FJG= 135
Step-by-step explanation:
∠FJG + ∠GJH = 168 so
(6x - 15) + (x + 8) = 168
7x - 7 = 168
7x = 175
x = 25
plug it in ∠FJG
6(25) - 15 = 135
