Answers
Complete Question:
In a jar there are 19 red jelly beans and 10 green jelly beans. In how many ways can you pick 4 red jelly beans and the same number of green jelly beans?
Answer:
[tex]Both = 813960[/tex]
Step-by-step explanation:
Given
Red Jelly Beans = 19
Green = 10
Required
Select 4 out of 19 red jelly beans and 4 out of 10 green jelly beans
The keyword in the question is pick and this implies combination;
4 from 19 red jelly beans is calculated as follows
[tex]^nC_r = \frac{n!}{(n-r)!r!}[/tex]
Where n = 19 and r = 4
[tex]^{19}C_4 = \frac{19!}{(19-4)!4!}[/tex]
[tex]^{19}C_4 = \frac{19!}{15!4!}[/tex]
[tex]^{19}C_4 = \frac{19 * 18 * 17 * 16 * 15!}{15! * 4 * 3 * 2 * 1}[/tex]
[tex]^{19}C_4 = \frac{19 * 18 * 17 * 16}{4 * 3 * 2 * 1}[/tex]
[tex]^{19}C_4 = \frac{93024}{24}[/tex]
[tex]^{19}C_4 = 3876[/tex]
Similarly;
4 from 10 green jelly beans is calculated as follows
[tex]^{10}C_4 = \frac{10!}{(10-4)!4!}[/tex]
[tex]^{10}C_4 = \frac{10!}{6!4!}[/tex]
[tex]^{10}C_4 = \frac{10 * 9 * 8 * 7 * 6!}{6! * 4 * 3 * 2 * 1}[/tex]
[tex]^{10}C_4 = \frac{10 * 9 * 8 * 7 }{4 * 3 * 2 * 1}[/tex]
[tex]^{10}C_4 = \frac{5040}{24}[/tex]
[tex]^{10}C_4 = 210[/tex]
Ways of selecting both is calculated as follows
[tex]Both = 3876 * 210[/tex]
[tex]Both = 813960[/tex]

Point C lies on BD, If BC = 52.39 mm and

37.11 mm

Answers
The length of the straight line → BD is 74.22 mm.
What is a line segment?A line segment is a piece or part of a line having two endpoints. Unlike a line, a line segment has a definite length.
Given is a line BD such that point C lies on BD. Also, BC = 52.39 mm and
CD = 21.83 mm.
We can say that for a straight line -
BD = BC + CD
The given measurements are -
BC = 52.39 mm
CD = 21.83 mm
Substituting the values, we get -
BD = 52.39 + 21.83
BD = 74.22 mm
Therefore, the length of the straight line → BD is 74.22 mm.

3. Which of the following quadratic equations has no solution? A) 0 = −2(x − 5)2 + 3 B) 0 = −2(x − 5)(x + 3) C) 0 = 2(x − 5)2 + 3 D) 0 = 2(x + 5)(x + 3)
Answers
Answer:
D) 0 = 2(x + 5)(x + 3)
Step-by-step explanation:
Which of the following quadratic equations has no solution?
We have to solve the Quadratic equation for all the options in other to get a positive value as a solution for x.
A) 0 = −2(x − 5)2 + 3
0 = -2(x - 5) × 5
0 = (-2x + 10) × 5
0 = -10x + 50
10x = 50
x = 50/10
x = 5
Option A has a solution of 5
B) 0 = −2(x − 5)(x + 3)
Take each of the factors and equate them to zero
-2 = 0
= 0
x - 5 = 0
x = 5
x + 3 = 0
x = -3
Option B has a solution by one of its factors as a positive value of 5
C) 0 = 2(x − 5)2 + 3
0 = 2(x - 5) × 5
0 = (2x -10) × 5
0 = 10x -50
-10x = -50
x = -50/-10
x = 5
Option C has a solution of 5
D) 0 = 2(x + 5)(x + 3)
Take each of the factors and equate to zero
0 = 2
= 0
x + 5 = 0
x = -5
x + 3 = 0
x = -3
For option D, all the values of x are 0, or negative values of -5 and -3.
Therefore the Quadratic Equation for option D has no solution.
The equation x2+y2−16x+6y+73=100 can be rewritten as [g(x)]2+(y+3)2=100.Write an expression for g(x).
Answers
Answer: g(x) = (x - 8)
Step-by-step explanation:
We start with the equation:
x^2 + y^2 - 16*x + 6*y + 73 = 100.
And we want to write this as:
g(x)^2 + (y + 3)^2 = 100.
So both equations are equal, then we can write this as:
x^2 + y^2 - 16*x + 6*y + 73 = g(x)^2 + (y + 3)^2
First we can expand the right side:
g(x)^2 + (y + 3)^2 = g(x)^2 + y^2 + 2*3*y + 9
Then we have:
x^2 + y^2 - 16*x + 6*y + 73 = g(x)^2 + y^2 + 6*y + 9
Now we can cancel the equal terms in each side, like y^2 and 6*y
x^2 - 16*x + 73 = g(x)^2 + 9
Now let's subtract 9 in each side:
x^2 - 16*x + 73 - 9 = g(x)^2
x^2 - 16*x + 64 = g(x)^2
Then we can assume that g(x) = (x - a)
then:
x^2 - 16*x + 64 = (x - a)^2 = x^2 - 2*a*x + a^2
-16*x + 64 = -2*a*x + a^2
now we must find the value of a, we have two equations:
-2*a = -16
a^2 = 64
and each equation yields to:
a = -16/-12 = 8.
a = √64 = 8
Then we have: g(x) = (x - 8)
Completing the squares, it is found that: [tex]g(x) = x - 8[/tex]
--------------------------------
The expression given is:
[tex]x^2 + y^2 - 16x + 6y + 73 = 100[/tex]
To complete the squares:
First, each first order term(-16 and 6) are divided by 2.Then, we write as the square of (x - 8) and (x + 3).Then, we have to find the squares on the other side of the equality.--------------------------------
Doing these steps:
[tex](x - 8)^2 + (y + 3)^2 = 100 - 73 + 8^2 + 3^2[/tex]
[tex](x - 8)^2 + (y + 3)^2 = 100 - 73 + 64 + 9[/tex]
[tex](x - 8)^2 + (y + 3)^2 = 100[/tex]
Which means that:
[tex]g(x) = x - 8[/tex]

If a sample is selected from a population, the sample mean is essentially guaranteed to be different from the population mean. In general, the naturally occurring difference between a sample statistic and the corresponding population parameter is called ____.
Answers
Answer:
Sampling Error
Step-by-step explanation:
We are told that the phenomenon is the naturally occurring difference between a sample statistic and the corresponding population parameter.
Now, it's sampling error because sampling error is simply defined as a deviation or difference in a sampled value as against the true population value due to the fact the sample is not a true representative of the population.
This is also similar to the definition given in the question.
Thus, it's sampling error!
A coin is flipped 25 times and lands on heads 16 times. Based on the experimental probability, how many heads would you predict for 200 flips of the coin?
Answers
Answer:
128 heads.
Step-by-step explanation:
From the experiment the probability = 16/25.
So the number of heads expected is (16/25) * 200
= 16 * 8
= 128.
Answer:
128 heads is the answer
Step-by-step explanation:
16/25=.64
.64*200=128
I would predict that it would land on heads 128 times if you flipped the coin 200 times.
GUYS PLEASE HELP ME ASAP!!!Jason is saving up to buy a new phone that costs $490 (I wish they were still this cheap). So far, he's saved $175. He would like to buy the camera no later than 3 weeks from now. What is the inequality used to represent how much he must save every week to have enough money to purchase the camera? (hint: when the wording is tricky, as it is in this problem, solve the problem as if it were an equation. That is to say, as if Jason was trying to save the money in exactly 3 weeks. Then decide on the sign that makes most sense).
Answers
Answer:
175-3x=490
Step-by-step explanation:
he only has 3 weeks, which is a time limit, so it would be -3x instead of +3x, he only has 175, so he needs more, so it's positive. Hope this is correct (:
Answer:

Step-by-step explanation:
Well you have the price of the phone which is $490 and you also have saved $175 towards the new phone.

For what value or values of b is it true that |b| = -b
Answers
Answer:
b =0
Step-by-step explanation:
The only value where |b| = -b is when b=0
|0| = -0
0 = 0
Absolute value means non- negative
non-negative = negative
This is only true when we equal zero
Answer: b = 0 or anything negative (like b = -2)
So any value of b such that [tex]b \le 0[/tex]
==================================================
Explanation:
|b| is the distance from b on the number line to 0
The distance is never negative as negative distance does not make sense.
If b was some positive number, then |b| = b. For instance, |7| = 7. This shows 7 is seven units away from 0 on the number line.
----------
If b is negative or zero, then |b| = -b. Why? Because the result of |b| is the opposite of whatever negative b value you put in. For example, b = -2 leads to
|b| = |-2| = 2
while
-b = -(b) = -(-2) = 2
The two negatives cancel each other out to get a positive result.
This shows, |-2| = -(-2) = 2
Meaning that the location -2 is two units away from 0 on the number line.
Elena plans to ride her bicycle 5 miles to a park and then ride several times around a loop in a the park that is 3 miles long. Then she'll take the same way home. she wants to ride a total of 22 miles. The inequality 3t + 10 ≥ 22 models this situation, where t is the number of times Elena went around the loop. Solve the inequality. How many times does Elena need to go around the loop?
Answers
Answer:
Solution : 4 or more times
Step-by-step explanation:
As the inequality is given to us, it makes this a bit simpler.
3t + 10 ≥ 22 ( Subtract 10 on either side )
3t ≥ 12 ( Divide 3 on either side )
t ≥ 12 / 3 ≥ 4
And hence we have a solution of t ≥ 4. Elena will ride around the loop 4 or more times.

What is Unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Calla lilies cost you $2.40.
roses cost $1.90.
If we need 65 lilies then it will cost
