Answer:

25

Step-by-step explanation:

Just by looking at this you can see the answer due to the format. Since all are multiplication you can cross out all the 190s. And you’re left with 75=50+_. Or to solve it, multiply what you were given to get 14250=9500+(190x_). Then subtract 9500: 4750=190x. Then divide by 190: x=25.

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]

For all the dogs: you have 2.65+2.46+3.67+2.91 = 11.69%

Now, the probability of getting a chihuahua would be 3.44/11.69=0.2942= 24.92

Step-by-step explanation:

there ya go....

Answer:

i think you add all the dogs which give you 2.65+2.46+3.67+2.91 = 11.69%

then for the  chihuahua  you add  3.44/11.69=0.2942= 24.92

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.

Answer:

9

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.

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.

This is called the product.

Step-by-step explanation:

Answer:

The result of a multiplication operation is called a product. The multiplication of whole numbers may be thought of as a repeated addition; that is, the multiplication of two numbers is equivalent to adding as many copies of one of them, the multiplicand, as the quantity of the other one, the multiplier.

Step-by-step explanation:

The expression that represents all clothing is being marked down 15%.

is A) 0.85x.

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
