Answer:
x = 3
Step-by-step explanation:
The equation can be rewritten to make use of the graphing calculator's ability to identify function zeros:
x(x -2)(x +3) -18 = 0
The attached shows x = 3 is the only real solution.
_____
We're not sure what "system of equations" is intended. Perhaps it is ...
y = 18
y = x(x -2)(x +3)
To create the expression we graphed, we effectively subtracted the first equation from the second.

An individual can win a bouncy ball by guessing under which one of four cups the ball is located. After each guess, if the ball is won, a new ball is placed randomly under one of the four cups. If the ball is not won, then the ball is again placed randomly under one of the four cups. If an individual makes five guesses, what is the probability the individual will win a prize exactly two times?
Answer:
I think that it is: [5 2] (.25)^2(.75)^3
Step-by-step explanation:
This looks like a binomial distribution problem. The formula for that is:
A common discrete distribution is used in statistics. The probability the individual will win a prize exactly two times out of five is 0.2637.
What is Binomial distribution?A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,
[tex]P(x) = ^nC_x p^xq^{(n-x)}[/tex]
Where,
x is the number of successes needed,
n is the number of trials or sample size,
p is the probability of a single success, and
q is the probability of a single failure.
The probability of getting a ball out of the four cups will be,
[tex]P = \dfrac14[/tex]
The probability of not getting the ball out of the four cups will be,
[tex]q = \dfrac34[/tex]
Now, using the binomial distribution the probability the individual will win a prize exactly two times out of five can be written as,
[tex]P(x) = ^nC_x p^xq^{(n-x)}\\\\P(x=2) = ^5C_2 \cdot (\dfrac{1}{4})^2\cdot (\dfrac34)^{(5-2)}\\\\P(x=2) = 10 \cdot \dfrac{1}{16} \cdot \dfrac{27}{64}\\\\P(x=2)=0.2637[/tex]
Hence, the probability the individual will win a prize exactly two times out of five is 0.2637.

. All clothing is being marked down 15%. Which expression represents the new retail price? A) 0.85x C 1.85x (B) 1.15x D 0.15x
Answer:
A
Hope that helps!
Step-by-step explanation:
The expression that represents all clothing is being marked down 15%.
is A) 0.85x.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
We know fractions and percentages are related.
Assuming the cost of clothing to be 'x'.
∴ After the markdown of 15% it is,
= {(100 - 15)/100}×x.
= {85/100}×x.
= 0.85x

Quadrilateral ABCD is inscribed in this circle.
What is the measure of angle A?
Answer:
Step-by-step explanation:
21 because x= tend + lHk
Answer:
88
Step-by-step explanation:
X° + 116° = 180°(sum of opposite angle of a quadrilateral in circle is equal 180 °)
x°=180-116
x°=64°
therefore
A=(2(64)-40)
A=88°

State whether each set of hypothesis is valid for a statistical test and briefly explain why ?
Complete Question:
State whether each set of hypothesis is valid for a statistical test and briefly explain why ?
[tex]H_0 : \mu=10; \ \ \ H_a : \mu\ne10[/tex]
[tex]H_0 : p \ne 0.5; \ \ \ H_a : p = 0.5[/tex]
[tex]H_0 : p_1 < p_2; \ \ \ H_a : p_1 \supset p_2[/tex]
Answer:
[tex]H_0 : \mu=10; \ \ \ H_a : \mu\ne10[/tex] --- Valid
[tex]H_0 : p \ne 0.5; \ \ \ H_a : p = 0.5[/tex] --- Invalid
[tex]H_0 : p_1 < p_2; \ \ \ H_a : p_1 \supset p_2[/tex] --- Invalid
Step-by-step explanation:
For a test of hypothesis to be valid, the null hypothesis has to contain some form of equality i.e. [tex]=, \le,\ or\ \ge[/tex]
So, the above will be used to test for validity in the given tests of hypotheses.
[tex]H_0 : \mu=10; \ \ \ H_a : \mu\ne10[/tex]
This is valid because the null hypothesis has an equality sign.
The null hypothesis is: [tex]H_0:\mu = 10[/tex]
[tex]H_0 : p \ne 0.5; \ \ \ H_a : p = 0.5[/tex]
This is invalid because the null hypothesis does not have any equality sign. The null hypothesis is: [tex]H_0:p \ne 0.5[/tex]
[tex]H_0 : p_1 < p_2; \ \ \ H_a : p_1 \supset p_2[/tex]
This is invalid because the null hypothesis does not have any equality sign. The null hypothesis is: [tex]H_0:p_1 <p_2[/tex]
