Answer:
x = y = 15[tex]\sqrt{2}[/tex]
Step-by-step explanation:
Using the sine ratio and the exact value
sin45° = [tex]\frac{\sqrt{2} }{2}[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{30}[/tex] = [tex]\frac{\sqrt{2} }{2}[/tex] ( cross- multiply )
2x = 30[tex]\sqrt{2}[/tex] ( divide both sides by 2 )
x = 15[tex]\sqrt{2}[/tex]
The triangle is isosceles (45- 45- 90) , then 2 legs are congruent, so
y = x = 15[tex]\sqrt{2}[/tex]

A spinner has two colored regions — purple and orange — and is divided in such a way so that the probability that the spinner lands on purple is 0.9. Suppose we spin the spinner 12 times and let X = the number of times it lands in the purple region.
Calculate the mean and standard deviation of X. Round to 4 decimal places, when necessary.

At a coffee shop, the first 100 customers'
orders were as follows.
Answer:
20%
Step-by-step explanation:
you add all the drink orders together for that category. in this situation its going to be cold drinks so you add 8 + 12 + 5 to get 25. then you divide by the drink size that its looking for. in this case its a large so you divide the drink size by the total, 5/25. the answer is 0.2. convert that to a fraction and get 20%
6. What would be the new coordinates
of point B if it was reflected across the
y-axis?
с
Answer:
(2, -4)Step-by-step explanation:
The rule for the reflection across the y-axis:
(x, y) → (-x, y)Coordinates of B is (-2, -4)
New coordinates of B:
(-2, -4) → (2, -4)Rule
(x,y)=(-x,y)
So
Old coordinate is (-2,-4)
New one

Answer:
The parallelogram ABCD is what makes the parallelogram.
The proof given was AC and BD bisect each other.
Bisect means to divide into 2 parts. AC and BD both divide into 2 parts with each other.
But the lines need to be in 2 equal parts.
So if we were to divide it in that case, it would be able to bisect.
This is given proof that parallelogram ABCD is a parallelogram.
Answer:
Solution given:
ABCD is a parallegram.
In ∆ADE and ∆BCE
AD=BC[corresponding side of parallelogram are equal]
<AED=<BEC[ vertically opposite angle]
<ADE=<EBC[alternate angle]
so
∆ADE are congruent to ∆BCE by S.A.A. axiom
we have
DE=BE[corresponding side of congruent triangle are equal]
Similarly
AE=CE
we have
AC=BD
AE+CE=BE+DE
2AE=2BE
AE=BE
so.we can rightly say that AC and BD bisect each other.

B.) How deep is the water after four hours?
C.) How long will take for the water to reach a depth of 80 inches?
Answer:
Each hour the water will rise 10 in. After 4 hours the water will be 40 in deep. It will take 8 hours for the water to reach a depth of 80 in.

Answer:
16 units
Step-by-step explanation:
For a right triangle, a²+b²=c², where a and b are leg lengths, and c is the hypotenuse. Given one leg length and the hypotenuse, we can find the other leg length by plugging in our given information:
a²+b²=c²
12²+b²=20²
144+b²=400
b²=256
b=16
Therefore, the missing leg length is 16 units.

A.
Answer: D. Pansy will take $25 per week from her account
Step-by-step explanation:
Based on the information given in the question, the true statement is that Pansy will take $25 per week from her account. This is represented by $25x.
For example, if the number of weeks that he used is 8 weeks. The amount in the savings account will be:
y = $25x + $500
y = $25(8) + $500
y = $200 + $500
y = $700

Vikram has a bucket of three different racquetballs, one blue, one black, and one red. He wants to test each ball to see how well they bounce. He reaches into the bucket and removes one ball without looking. He hits the ball against the wall, catches it, and then drops it back into the bucket. He repeats this process twice more, each time choosing a ball without looking.
Part A:
What is the probability that Vikram hits the blue ball, then the black ball, and then the red ball?
Answer:
Part B:
If Vikram does not drop the balls back into the bucket after he hits them, what is the probability that Vikram hits the blue ball, then the black ball, and then the red ball?
Answer:
Answer:
A) 33.3%
B) 50 %
Step-by-step explanation:
A) if there are 3 balls always in the bucket you need to see what one balk represent one ball is 1÷3 which is 0.33 so by knowing that if Vikram drops the ball back into the bucket after the hit there would be a 33 % chance he will chose the same or a different ball in order.
B)if he won't put the ball back in the bucket there will be only 2 balls felt so 1÷2 = 0.5 so there is a 50 % chance of Victor getting the balls in the correct order
