Answer:

Step-by-step explanation:

This is a test of 2 independent groups. The population standard deviations are not known. Let μ1 be the mean weight loss yield of the powder diet and μ2 be the mean weight loss yield of the liquid diet.

The random variable is μ1 - μ2 = difference in the mean weight loss yield of the powder diet and the mean weight loss yield of the liquid diet.

We would set up the hypothesis.

The null hypothesis is

H0 : μ1 = μ2 H0 : μ1 - μ2 = 0

The alternative hypothesis is

H1 : μ1 < μ2 H1 : μ1 - μ2 < 0

This us a left tailed test.

Since sample standard deviation is known, we would determine the test statistic by using the t test. The formula is

(μ1 - μ2)/√(s1²/n1 + s2²/n2)

From the information given,

μ1 = 42

μ2 = 45

s1 = 12

s2 = 14

n1 = 49

n2 = 36

t = (42 - 45)/√(12²/49 + 14²/36)

t = - 1.04

The formula for determining the degree of freedom is

df = [s1²/n1 + s2²/n2]²/(1/n1 - 1)(s1²/n1)² + (1/n2 - 1)(s2²/n2)²

df = [12²/49 + 14²/36]²/[(1/49 - 1)(12²/49)² + (1/36 - 1)(14²/36)²] = 70.28/1.03

df = 68

We would determine the probability value from the t test calculator. It becomes

p value = 0.15

Assuming a significance level of 0.05, then

Since alpha, 0.05 < than the p value, 0.15, then we would fail to reject the null hypothesis. Therefore, we can conclude that at a 5% significance level, the liquid diet does not yield a higher mean weight loss than the powder diet.

Answer:

x = -7

Step-by-step explanation:

Solve for x:

4 (1 - x) + 2 x = -3 (x + 1)

4 (1 - x) = 4 - 4 x:

2 x + 4 - 4 x = -3 (x + 1)

2 x - 4 x = -2 x:

-2 x + 4 = -3 (x + 1)

Expand out terms of the right hand side:

4 - 2 x = -3 x - 3

Add 3 x to both sides:

3 x - 2 x + 4 = (3 x - 3 x) - 3

3 x - 3 x = 0:

3 x - 2 x + 4 = -3

3 x - 2 x = x:

x + 4 = -3

Subtract 4 from both sides:

x + (4 - 4) = -4 - 3

4 - 4 = 0:

x = -4 - 3

-4 - 3 = -7:

Answer:  x = -7

Answer:

X=-7

Answer:

The average temperature after 200 kilometers of journey is -4 °C.

Step-by-step explanation:

The situation shows that change in average temperature is directly proportional to travelled distance:

[tex]T = 2^{\circ}C - \frac{3^{\circ}C}{100\,km} \cdot (200\,km)[/tex]

[tex]T = -4^{\circ}C[/tex]

The average temperature after 200 kilometers of journey is -4 °C.

Answer:

The temperature after 200 km of its journey is -4°C

Step-by-step explanation:

To find the new temperature, first, you need to find how much the temperature decreases, and then subtract this temperature decrease to the initial temperature.

The temperature decreases 3°C for every 100 km travelled, then, after 200 km the temperature decreases 2*3 = 6 °C.

At the start of the bear's journey, the temperature was 2 °C, after 200 km the temperature is 2 - 6 = -4°C

Answer:

140 people in Ivy's workforce

Step-by-step explanation:

First, add together the 79 workers and the 5 extra people.

79 + 5 = 84

Now take 84 divided by 3/5 to find the number of people who are in the workforce.

84/ 3/5 = 140 people in Ivy's workforce

Answer:

140

Step-by-step explanation:

First, add together the 79 workers and the 5 extra people.

79 + 5 = 84

Now take 84 divided by 3/5 to find the number of people who are in the workforce.

84/ 3/5 = 140 people in Ivy's workforce

Answer:

y = x2 − 500x + 60,000

Step-by-step explanation:

The length of the fenced-in section is (x − 200) feet, and the width is (x − 300) feet.

area of the fenced-in section = length • width

y = (x − 200)(x − 300)

= x2 − 300x − 200x + 60,000

= x2 − 500x + 60,000

Answer:

y= x^2 − 500x + 60,000

Step-by-step explanation:

Other loser made a mistake

The length of the fenced-in section is (x − 200) feet, and the width is (x − 300) feet.

area of the fenced-in section = length • width

y = (x − 200)(x − 300)

= x^2 − 300x − 200x + 60,000

= x^2 − 500x + 60,000

Answer:

X: amount of a spare part of price $74 per unit.

Y: cost of purchasing X spare parts.

Step-by-step explanation:

We can imagine that X represents the amount of an object, for example a car spare part,  which price is $74 per unit.

Then, Y would represent the cost of purchasing X units of that spare part.

Answer:

31.25

Step-by-step explanation:

Firstly, we need to identify the pattern.

Pattern: every next number is obtained by dividing the previous number by 2.

1st number = 1000

2nd number = 1000/2 = 500

3rd number =  500/2 = 250

4th number = 250/2 = 125

5th number = 125/2 = 62.5

6th number = 62.5/ 2 = 31.25.

_______________________________________________

It can be also solved using concept of geometric progression

In GP

any nth number is given by = [tex]ar^(n-1)[/tex]

where a is first number

r is the common ratio for the gp

r common ratio is calculated by = nth/(n-1)th

here r = 500/1000 = 1/2

a = 1000

next term which we need to find is 6th terms

Thus, 6th terms = [tex]1000*(1/2)^(6-1)[/tex]

 [tex]=1000/2^5[/tex]

=1000/32 = 31.25

Answer:

4 x (x + 5)^2

Step-by-step explanation:

Factor the following:

4 x^3 + 40 x^2 + 100 x

Factor 4 x out of 4 x^3 + 40 x^2 + 100 x:

4 x (x^2 + 10 x + 25)

The factors of 25 that sum to 10 are 5 and 5. So, x^2 + 10 x + 25 = (x + 5) (x + 5):

4 x (x + 5) (x + 5)

(x + 5) (x + 5) = (x + 5)^2:

Answer: 4 x (x + 5)^2

Answer:

  4 and -10

Step-by-step explanation:

Take the square root:

  x +3 = ±√49 = ±7

Subtract 3:

  x = -3 ± 7

For the minus sign, we have ...

  x = -3 -7 = -10

For the plus sign, we have ...

  x = -3 +7 = 4

The solutions are x = 4 and x = -10.

The solutions of the quadratic equation x = 4 and x = –10

Answer:

50 minutes

Step-by-step explanation:

Time when patty goes to mall = 9:30 am

Time when he has to meet a friend = 11.15 Am

Spare time patty has is interval between Time when he has to meet a friend

and Time when patty goes to mall

which can be written as

Spare time patty has = 9:30 am to 10:30 am which is 1 hours 45 mins.

One hour has 60 minutes.

Thus total time in minutes patty has = 1*60 minutes + 45 minutes = 105 minutes.

Time which will be used by Patty to have lunch = 55 minutes.

Time left out if 55 minutes are used in lunch = total spare time - time for lunch = (105 - 55 ) minutes = 50minutes.

Patty wants to shop in the spare time after allocating 55 minutes to lunch.

Thus the rest of time which is 50 minutes, he can use to shop.

Answer:

Step-by-step explanation:

16x^4y^-3z^4 / 36x^-2yz^0

16x^4y^-3z^4 = 16x^4z^4/y^3

36x^-2yz^0 = 36x^-2y(1) =36x^-2y = 36y/x^2

16x^4y^-3z^4 / 36x^-2yz^0

= (16x^4z^4/y^3) / (36y/x^2)

= 16x^4z^4/y^3 * x^2/36y  

= (4/9)x^6z^4/y^4

or another way

fist multiply it out

f(x) = 4x^(3/5) - x^(8/5)

now differentiate knowing d/dx(x^n) = n x^(n-1)

to get

4*(3/5) x^(-2/5) - 8/5 x^(3/5)

simplify to get

12/5/x^(2/5) -   8/5 x^(3/5)

Answer:

  $3.00 < $15.00

Step-by-step explanation:

It is unusual to see a dollar amount with three digits to the right of the decimal point. (This sometimes happens when prices are expected to be multiplied by large quantities.) On the other hand, it sometimes happens that a period gets substituted for a comma. So, some relevant inequalities might be ...

  $3.00 < $15

  $3,000 > $15

Answer:

A. The alternative hypothesis is less than.91/Do not reject the null

Null hypothesis: H0 = 0.91

Alternative hypothesis: Ha < 0.91

z = -1.24

P value = P(Z<-1.24) = 0.11

Rule

If;

P-value > significance level --- accept Null hypothesis

P-value < significance level --- reject Null hypothesis

Z score > Z(at 95% confidence interval) ---- reject Null hypothesis

Z score < Z(at 95% confidence interval) ------ accept Null hypothesis

Step-by-step explanation:

Given;

n=200 represent the random sample taken

Null hypothesis: H0 = 0.91

Alternative hypothesis: Ha < 0.91

Test statistic z score can be calculated with the formula below;

z = (p^−po)/√{po(1−po)/n}

Where,

z= Test statistics

n = Sample size = 200

po = Null hypothesized value = 0.91

p^ = Observed proportion = 177/200 = 0.885

Substituting the values we have

z = (0.885-0.91)/√(0.91(1-0.91)/200)

z = −1.23541552776

z = -1.24

To determine the p value (test statistic) at 0.05 significance level, using a one tailed hypothesis.

P value = P(Z<-1.24) = 0.107488 = 0.11

Since z at 0.05 significance level is between -1.96 and +1.96 and the z score for the test (z = -1.24) which falls with the region bounded by Z at 0.05 significance level. And also the one-tailed hypothesis P-value is 0.11 which is higher than 0.05. Then we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can say that at 5% significance level the null hypothesis is valid, therefore do not reject null.
