Amelia recorded the heights, in centimeters, and ages, in weeks, of pepper plants in her garden.

baherus [9]

Equation: y=4x+6

When x = 1
y=4(1)+6
y=4+6
y=10

When x=3
y=4(3)+6
y=12+6
y=18

and so on........

If Logx (1 / 8) = - 3 / 2, then x is equal to

babymother [125]

The answer is B. 4

Rewrite the logarithmic equations using exponential equation

x- 3 / 2 = 1 / 8

The above equation may be rewritten as

x - 3 / 2 = 1 / 23 = 2-3

(√x)-3 = 2-3

The above equation gives

√x = 2 or x = 4

Wilson wants to know how long it will take his $1000 investment to double

riadik2000 [5.3K]

Answer:

Step-by-step explanation:

Take the log of both sides:

log(2) = t*log 1.015, so that:

log(2)

t = --------------- = 46.6 compounding periods, which is 46.6/4, or 11.6 years

log 1.015

Can't write this exponential equation as a logarithm; instead, CAN write it in logarithmic form.

Use the given information to find the p-value. also use a0.05 significance level and state the conclusion about the null hypothe

omeli [17]

Answer:

(a) C: 0.0465 ; reject the null hypothesis

(b) B: 0.3409 ; fail to reject the null hypothesis

Step-by-step explanation:

Firstly, the decision rule based on P-value to reject the null hypothesis or fail to reject the null hypothesis is given by;

If the P-value of test statistics is less than the level of significance, then we have sufficient evidence to reject our null hypothesis.

If the P-value of test statistics is more than the level of significance, then we have insufficient evidence to reject our null hypothesis due to which we fail to reject our null hypothesis.

(a) Now, we are given alternate hypothesis, $H_1$ : p < 3/5

Also, z test statistics is -1.68. Since this is a left tailed test, so P-value is given by;

P-value = P(Z < -1.68) = 1 - P(Z $\leq$ 1.68)

= 1 - 0.95352 = 0.0465

Since, the P-value of test statistics is less than the level of significance as 0.0465 < 0.05, so we have sufficient evidence to reject our null hypothesis due to which we reject the null hypothesis.

(b) Now, we are given alternate hypothesis, $H_1$ : p > 0.383

Also, z test statistics is 0.41. Since this is a right tailed test, so P-value is given by;

P-value = P(Z > 0.41) = 1 - P(Z $\leq$ 0.41)

= 1 - 0.6591 = 0.3409

Since, the P-value of test statistics is more than the level of significance as 0.3409 > 0.05, so we have insufficient evidence to reject our null hypothesis due to which we fail to reject the null hypothesis.
