Solve for z in the literal equation 5/8 (z + 11) = y.

SVEN [57.7K]

Answer:

11. (x-2)/(x+8)

12. 9+t

13. h = 2A/b

Step-by-step explanation:

11. Since x is used to represent the number, 2 less than a number is x-2. 8 more than a number is x+8. The quotient of the first and second of these is the first one divided by the second one:

... (x -2)/(x +8) . . . . . parentheses are required unless the expression is typeset:

$\dfrac{x-2}{x+8}$

12. Apparently, we're to assume the salesman keeps on driving. If he had any sense (or a good union), he would stop after 9 hours. t hours added to 9 is ...

... 9 + t

13. Divide by the coefficient of h.

... h = A/((1/2)b) = 2A/b

The growth rate of the sunflower from day 14 to day

nata0808 [166]

Option B) h = 4.5t – 27 is the equation of the straight line that best models the height h, in centimeters, of the sunflower t days after it begins to grow.

From the above graph we can see that from day 14 to day 35 , it is a straight line.

And equation of a straight line is y = mx + c or y – y1 = m(x – x1)

Where, m =slope of the line

c = intercept

the equation can be rewritten as h – h1 = m(t – t1) (1)

So, to find the equation of line , first we will calculate the slope of the line.

To find the slope : m = (h2 – h1 ) / (t2 – t1) (2)

From the graph and the table given, the coordinates (t1 , h1 ) and ( t2 , h2 ) are (14 , 36.6) and (35, 131) respectively.

Putting these values in equation (2), we get

m = (131 – 36.6)/(35 – 14)

m = 94.4/21

m = 4.5

now to find the equation of line we put the values in equation (1), we get

h – 36.6 = 4.5(t – 14)

h – 36.6 = 4.5t – 63

h = 4.5t -63 + 36.6

h = 4.5t -27

Hence the equation of the line is , option B) h = 4.5t -27

True or False: A p is the probability that the results are not due to chance, the probability that the null hypothesis (H0) is f

professor190 [17]

Answer:

False

Step-by-step explanation:?

The hypothesis tests compare weather an event is meant to alter a population mean results, for example, a scientist experiment might have or not have a significant effect over the population results. The test aims to reject the null hypothesis, so what it really want to find out is if the alternative Hypothesis H1 is likely true. The null hypothesis is the probability that the results are not due to chance – if it’s rejected, then the results are due to chance.The level of significance , or so called p-value, is the probability that the null hypothesis (H0) happen , If p is very small then the null hypothesis is rejected - isn’t true- and the alternative Hypothesis is accepted. A higher P value implies a higher probability than results are not happening so that the H0 is accepted and H1 rejected. The null Hypothesis will normally will rejected when the level of significance are either lower than 0.05 or 0.01, the lower P value the higher the level of confidence that the results are due to chance.

Since the first part of the statement (A p is the probability that the results are not due to chance) is correct, and the second part is wrong (…the probability that the null hypothesis (H0) is false), the total statement is false. The correct statement would be as follows : A p is the probability that the results are not due to chance, the probability that the null hypothesis (H0) is true.
