Please help me find the area of compound shapes?!?!
Answer:
[tex]27cm^{2}[/tex]
Step-by-step explanation:
Area of compound shapes = Area of shape A + Area of shape B
Area of this shape = (L x B) + (L x B)
= (5 x 3) + (6 x 2)
= 15 + 12
= [tex]27cm^{2}[/tex]
Answer:
A = 27 cm²
Step-by-step explanation:
the figure consists of 2 rectangles
the one on the right with dimensions 2 cm by 6 cm and
the one on the left with dimensions 5 cm by 3 cm
the total area (A) is then calculated as
A = (2 × 6) + (5 × 3) = 12 + 15 = 27 cm²

When developing functions a, b, and c, the studio restricted the domain of each function to the interval [0, 10). What are
some possible reasons for restricting the domain in this way?
Answer: The domain wouldn’t include negative because it’s not possible to backward in time. The studio might limit the domain to numbers less than or equal to 10 because for x > 10 the number of views is unrealistically big. Also, viral marking slow after a while so the functions may not fit the data as well after 10 days.

In the last 10 presidential elections, the democratic candidate has won six times in Michigan and four times in Ohio. What is the probability that the democratic candidate wins both Michigan and Ohio in the next presidential election?
0.24 is the probability that the democratic candidate wins both Michigan and Ohio in the next presidential election
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given,
In the last 10 presidential elections, the democratic candidate has won six times in Michigan and four times in Ohio
We need to find the probability of that the democratic candidate wins both Michigan and Ohio in the next presidential election
As 6 wons from Michigan out of 10, so it 6/10
4 wons from Ohio out of 10, so it 4/10
The probability is 6/10/×4/10
24/100=0.24
In the next year also democratic candidate wons then the probabiltiy will be same 0.24
Hence 0.24 is the probability that the democratic candidate wins both Michigan and Ohio in the next presidential election

Suppose that you have 8 green cards and 5 yellow cards. The cards are well shuffled. You randomly draw two cards without replacement.
Your question is Incomplete. Please read below for the missing content.
Total cards = 8 + 5 = 13
The selections are being made with replacement. Hence,
a) P(G1 and G2) = P(G1)*P(G2) = (8/13)*(8/13) = 0.3787
b) P(Atleast 1 green) = 1 - P(No green) = 1 - (5/13)*(5/13) = 0.8521
c) P(G2 | G1) = P(G2) = 8/13 = 0.6154
What is the probability of replacement?
Probability with replacement is used for questions where the outcomes are back again to the sample space again. which means that when the object is selected, then its miles changed and returned to the sample space, so the range of elements of the sample space remains unchanged.
Conclusion: The chance of two consecutive attracts without a replacement from a deck of playing cards is calculated because the range of viable successes over the variety of viable results, is expanded together for each case. accordingly, for the primary ace, there may be a 4/52 possibility and for the second there is a 3/51 probability.

Kelly used the vertical line test to determine whether or not the curve that she
had been given is a function. After conducting the vertical line test, Kelly
determined that the curve is a function. Which of the following choices
represents the result of Kelly's vertical line test?
A. All vertical lines intersected the curve at exactly 2 points.
B. One vertical line intersected the curve at exactly 2 points.
C. One vertical line intersected the curve at exactly 1 point, while
another vertical line intersected the curve at exactly 2 points.
OD. All vertical lines intersected the curve at exactly 1 point.
All vertical lines intersected the curve at exactly 1 point.
===========================================================
Explanation:
If there is a case when a single vertical line crosses 2 or more points on the curve, then it will not be a function. In this situation, it is said that the curve fails the vertical line test.
Passing the vertical line test means that every vertical line passes through exactly one point on the curve. Each x input leads to exactly one output. If such a situation happens, then we have a function.
Since Kelly concluded that the curve is a function, this means the curve passed the vertical line test, and it points us to choice D as the answer.

To find side given angle and two sides:
a² = b² + c² − 2bc cos(A)
Here given:
a = AC cmb = 10 cmc = 7 cmangle A = 120°Solve for AC (a):
a² = (10)² + (7)² − 2(10)(7) cos(120)a² = 219a = √219a = 14.7986 cma = 14.8 cmAnswer:
AC = 14.8 cm (1 dp)
Step-by-step explanation:
Cosine rule
[tex]\sf b^2=a^2+c^2-2ac \cos B[/tex]
(where a, b and c are the sides, and B is the angle opposite side b)
Given:
a = 10 cmc = 7 cmB = 120°b = ACSubstituting the given values into the formula and solving for b:
[tex]\implies \sf AC^2=10^2+7^2-2(10)(7) \cos 120^{\circ}[/tex]
[tex]\implies \sf AC^2=100+49+70[/tex]
[tex]\implies \sf AC^2=219[/tex]
[tex]\implies \sf AC=\pm\sqrt{219}[/tex]
As length is positive,
