Answer:
[tex]\text{1. }\triangle IJH\cong \triangle LKM, \\\text{2. }\triangle RST\cong \triangle YXZ, \\\text{3a. Reflexive Property}, \\\text{3b. ASA (Angle-Side-Angle)}[/tex]
Step-by-step explanation:
ASA (Angle-Side-Angle) is a proof of congruence that states if two triangles share two angles and the side between those two angles, the triangles are congruent. In problems 1 and 2, the following demonstrate this:
[tex]\text{1. }\triangle IJH\cong \triangle LKM, \\\text{2. }\triangle RST\cong \triangle YXZ[/tex]
In problem 3, [tex]\overline{IJ}\cong \overline{IJ}[/tex] is known in geometry as the Reflexive Property. Because of this, the two triangles in the diagram for problem 3 now share two angles and the side between them, thus they are congruent from ASA (Angle-Side-Angle).
10. Last year, a state university received 3.560 applications from boys. Of
those applications, 35% were from boys who lived in other states. Part A
How many applications did the university receive from boys who lived in
other states? Show how you found the answer for full credit
Answer:
1.246
Step-by-step explanation:
First, you divide 3.560 by 100%, which gives you 3.56. Now since you have the number of applications received each, you now multiply 3.56 by 35%, or 0.35, which then gives you 1.246.

what is the equation of the line that is parallel to 3x-y=4 and goes through the point (3,2).
Answer:
Step-by-step explanation:
In parallel lines gradient are the same so first re-arrange the given equation.
1. Ax+By=C
2. The equation is given in standard format [tex]3x-y=4[/tex]
Solve for m.
1. [tex]3x-y=4[/tex]
2. [tex]\frac{3x}{3} =\frac{4}{3}+\frac{y}{3}[/tex]
3. [tex]x=\frac{4}{3}+\frac{y}{3}[/tex]
Find the value of b using the formula for the equation of line.
[tex]y=mx+b[/tex]
Substitute the value of m into the equation.
[tex]y=(\frac{4}{3}+\frac{y}{3}) . x+b[/tex]
Substitute the value of x into the equation
[tex]y=(\frac{4}{3}+\frac{y}{3}).(3)+b[/tex]
Substitute the value of y into the equation
[tex]2=(\frac{4}{3}+\frac{2}{3}).(3)+b[/tex]
Find B
[tex]b= -4[/tex]
Now we know the value of m and b. Substitute them into y=mx+b to find the equation of the line.
[tex]y=\frac{4}{3} x+\frac{1}{3} yx-4[/tex]

Can someone please please help me with my math , english and health questions. im failing in all these classes and extremely need help. Some already have one answer but it isnt correct or someone just wrote down stuff just to get points. ( Will Mark Brainliest for each correct answer).
Answer:
okie we will try our best
Please guys help me.
Answer:
Option B
Step-by-step explanation:
For the polygons to be similar, the dilation ratio must be uniform for all sides.
>> In option A, each side of the bigger hexagon is 8cm while each side of the smaller one is 5 cm. Thus, the dilation ratio is uniform at 8:5. Thus, they are similar polygons.
>> In option B, the longer side of the big rectangle is 12 inches and reduces to 10 inches. Which means a ratio of 6:5 whereas, the shorter side reduces from 7 to 6 which is a ratio 7:6. Since both ratios are different, then it means that both rectangles are not similar.
>> In option C, the hypotenuse of the big triangle is 15 m and reduces to 10 m in the small triangle. This gives a ratio of 3:2.
The perpendicular side of the big triangle is 9m which reduces to 6 m in the small one. This is a ratio of 3:2.
The horizontal side of the big triangle 12m which reduces to 8m in the small triangle. This is a ratio of 3:2.
Since all the ratios are same, then they are similar triangles.
>> In option D, each side of the bigger polygon is 7ft while each side of the smaller one is 4ft. Thus, the dilation ratio is uniform at 7:4. Thus, they are similar polygons.

The diagram shows the locations of Gabe’s house, a library, and a gymnasium. Each unit on the grid represents 1 kilometer.
Part A: What is the distance between Gabe’s house and the library?
A. 4 kilometers
B. 5 kilometers
C. 3 kilometers
D. 6 kilometers
The distance between gab's house and library will be 4km
What is Distance?
Distance is a numerical measurement of how far apart object or point are or it may also refer as the physical length.
From graph we can see that Gabe's house is 3 km on positive x axis in respect to the origin
Whereas library is 1 km apart from origin on negative x axis
Since we are calculating distance , we simply add both the above mentioned distances irrespective of their direction since distance is a scaler quantity.
Distance between Gab's house and library will be :
D = |3| + |-1|
D = 3+1 = 4 km option A)

. Let X and Y be random variables of possible percent returns (0%, 10%,
15%, and 20%) for stock A and, with the joint probability distribution given
in the Table below:
Joint Probability Distribution for Random Variables X and Y
Y Return
X Return 0 5 10 15
0 0.0625 0.0625 0.0625 0.0625
5 0.0625 0.0625 0.0625 0.0625
10 0.0625 0.0625 0.0625 0.0625
15 0.0625 0.0625 0.0625 0.0625
(a) Find the marginal probabilities.
(b) Determine if X and Y are independent.
(c) Find the means and variances of both X and Y.
(a) The marginal distribution of X is
Pr(X = x) = ∑ Pr(X = x, Y = y)
… = 0.0625 + 0.0625 + 0.0625 + 0.0625
… = 0.25
That is, the first equality follows from the law of total probability, with the sum taken over y from {0, 5, 10, 15}. Each probability Pr(X = x, Y = y) is given in the table to be 0.0625.
Similarly, the marginal distribution of Y is
Pr(Y = y) = 0.25
(b) Yes, they're independent because
Pr(X = x, Y = y) = 0.0625,
and
Pr(X = x) Pr(Y = y) = 0.25 • 0.25 = 0.0625.
(c) The mean of X is
E[X] = ∑ x Pr(X = x)
… = 0.25 ∑ x
… = 0.25 (0 + 5 + 10 + 15)
… = 7.5
and you would find the same mean for Y,
E[Y] = 7.5
The variance of X is
V[X] = E[X^2] - E[X]^2
… = (∑ x^2 Pr(X = x)) - 7.5^2
… = 0.25 (∑ x^2) - 56.25
… = 0.25 (0^2 + 5^2 + 10^2 + 15^2) - 56.25
… = 31.25
and similarly,
V[Y] = 31.25
(each sum is taken with x and y from {0, 5, 10, 15})
Anthony can either play 4 hours of video games or read 12 chapters of a book. What is Anthony's opportunity cost of playing one hour of video games?
Answer:
The opportunity cost of playing an hour of video games is not reading 3 chapters of a book.
Step-by-step explanation:
Given that Anthony can either play 4 hours of video games or read 12 chapters of a book, to determine what is Anthony's opportunity cost of playing one hour of video games, the following calculation must be performed:
4 = 12
1 = X
1 x 12/4 = X
12/4 = X
3 = X
Therefore, the opportunity cost of playing an hour of video games is not reading 3 chapters of a book.

One pile of cards contains the number 2 through 6 in red hearts. A second pile of cards contains the numbers 4 through 8 in black spades. Each pile of cards has been randomly shuffled. If one card from each pile is chosen at the same time, what is the probability that the sum will be less than 12?
Answer:
19/25.
Step-by-step explanation:
The total possible number of combinations of 2 cards from the 2 piles = 5*5 = 25.
Possible ways to get sum of 12 or more =
4,8 5,7 5,8 6,6 6,7 6,8 = 6 ways.
So the number of ways to get sum of < 12 = 25 - 6 = 19.
So the required probability = 19/25.
Answer:
I think the probability is 19 out of 25 = 19/25, but I am not sure so please check by step by step solution.

A motorboat travels 204 kilometers in 6 hours going upstream. It travels 372 kilometers going downstream in the same amount of time. What is the rate of the boat in still water and what is the rate of the current?
9514 1404 393
Answer:
boat: 48 km/hcurrent: 14 km/hStep-by-step explanation:
The upstream speed is ...
u = (204 km)/(6 h) = 34 km/h
The downstream speed is ...
d = (372 km)/(6 h) = 62 km/h
The speed of the boat in still water is the average of these values:
b = (34 kph +62 kph)/2 = 48 kph
The speed of the water is the difference between the boat's speed and the speed made good:
w = 48 -34 = 14 . . . km/h
The rate of the boat in still water is 48 km/h. The rate of the current is 14 km/h.
