Answer:

13/24

can't be simplified

Step-by-step explanation:

you can make them have the same denominator by multiplying.

denominator of 24 is 8*3

and 3*8

then multiply their numerators by the same values

7/8 times 3= 21/24

1/3 times 8= 8/24

subtract

21-8= 13

so 13/24

Answer:

The decision rule will be as follows: Reject the null hypothesis if test-statistic < -2.5 or fail to reject the

Now, Our test-statistic was -1.96, which is greater than -2.5. Thus, we will fail to reject the null hypothesis.

Step-by-step explanation:

We are given;

Population mean; μ = 432

Sample mean; x¯ = 426

Sample size; n = 24

Variance; Var = 225

Now, standard deviation from variance is; σ = √Var

Thus, σ = √225

σ = 15

Hypothesis is defined as;

Null hypothesis; H0: μ ≥ 432

Alternative hypothesis: Ha: μ < 432

Formula for the test statistic since sample size is less than 30 is;

t = (x¯ - μ)/(σ/√n)

Plugging in the relevant values;

t = (426 - 432)/(15/√24)

t = -1.96

Now,we are given significance level of 0.01; our DF = n - 1 = 24 - 1 = 23.

From t-table attached, we can see that at DF of 23 and significance value of 0.01, the critical value is 2.5

However, this is a left tailed test as the rejection region is to the left.

Thus, the critical value of a left tailed test is negative. Thus, in this case our critical value will be -2.5.

The decision rule will be as follows: Reject the null hypothesis if test-statistic < -2.5 or fail to reject the

Now, Our test-statistic was -1.96, which is greater than -2.5. Thus, we will fail to reject the null hypothesis.

Answer:

B

Step-by-step explanation:

The answer is B. If you look at the graph at its current state you can see that the lines are parallel to each other. This is important because it says TWO lines are being translated and rotated. So whatever happens to one line happens to the other line which proves they were always parallel to each other.

Answer:

(7x + 1)(x - 7).

Step-by-step explanation:

y = 7x^2 - 48x - 7

Use the 'ac' method:

7 * 7 = 49

Now we need 2 numbers whose product is  49 and whose sum is the 'middle' number -48.

They are -49 and 1,

Now we write the function as:

7x^2 - 49x + 1x - 7

= 7x((x - 7) + 1(x - 7)           (x - 7) is common so we have

(7x + 1)(x - 7).

Answer:

0.9772 = 97.72% probability that a randomly generated value of X is greater than a randomly generated value of Y

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question:

[tex]\mu_X = 45, \sigma_X = 4, \mu_Y = 35, \sigma_Y = 3[/tex]

What is the probability that a randomly generated value of X is greater than a randomly generated value of Y

This means that the subtraction of X by Y has to be positive.

When we subtract two normal variables, the mean is the subtraction of their means, and the standard deviation is the square root of the sum of their variances. So

[tex]\mu = \mu_X - \mu_Y = 45 - 35 = 0[/tex]

[tex]\sigma = \sqrt{\sigma_X^2+\sigma_Y^2} = \sqrt{25} = 5[/tex]

We want to find P(X > 0), that is, 1 subtracted by the pvalue of Z when X = 0. So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{0 - 10}{5}[/tex]

[tex]Z = -2[/tex]

[tex]Z = -2[/tex] has a pvalue of 0.0228

1 - 0.0228 = 0.9772

0.9772 = 97.72% probability that a randomly generated value of X is greater than a randomly generated value of Y

Answer:

35

Step-by-step explanation:

We solve the above question using z score formula

z = (x-μ)/σ, where

x is the raw score = ?

μ is the population mean = 70

σ is the population standard deviation = 14

We were given the z score in the question as: Two and one half standard deviations below the mean

Hence:

= μ - zσ

= 70 - 2.5(14)

= 70 - 35

= 35

The score that is two and one half standard deviations below the mean is 35

What is graph?

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

As, per the graph we can see that the range for y starts from negative infinity but it only exceeds upto +4.

Hence, the range is -∞ < y ≤ 4.

Step-by-step explanation:

11 packs of cards at 75 cents each.

Step-by-step explanation:

Given

[tex]h(t)=(139kt)^2-69t+80[/tex]

For roots [tex]h(t)=0[/tex]

[tex](139kt)^2-69t+80=0\\t=\dfrac{69\pm\sqrt{(-69)^2-4\times (139k)^2(80)}}{2\times 139}\\[/tex]

[tex]t=\dfrac{69\pm\sqrt{4761-6182720k^2}}{278}[/tex]
