What Is The Value Of X?

Answers

Answer 1

x^2 + 21^2 = 29^2

x^2 + 441 = 841

x^2 = 841 - 441

x^2 = 400

x = √400

x = 20

The data are from the Food and Drug Administration. Use a 0.05 significance level to test the claim that the three samples are from populations with the same mean. Assume that the distributions for each state are normal and that all variances are equal.

No, the claim that the three samples are from populations with the same mean is not correct and this can be determined by using the given data.

Given :

The amounts are in micrograms of arsenic and all samples have the same serving size. The data are from the Food and Drug Administration. Use a 0.05 significance level.

The Hypothesis test is given below:

Null Hypothesis: [tex]H_0:\mu_1=\mu_2=\mu_3[/tex]

Alternative Hypothesis: [tex]H_a:\mu_1\neq \mu_2\neq \mu_3[/tex]

For the F-test, the test statistics is given by:

[tex]F = \dfrac{MS_{\rm{between}}}{MS_{\rm{within}}}[/tex]

Now, substitute the values of known terms in the above expression.

[tex]F = \dfrac{15.8252}{0.6896}[/tex]

[tex]F = 22.95[/tex]

So, the p-value regarding the value of F is:

[tex]P-value=P(F>22.95)[/tex]

[tex]P-value = 1.0.9999[/tex]

[tex]P-value = 0.0001[/tex]

The Null Hypothesis is rejected because P-value is less than the significance value.

Step-by-step explanation:

Let the coordinates of point b be (x,y).

Given the coordinates of a (-7,5) and c(5,-1)

Now according to question

ab = 5bc

using distance formula

What is the distance between (-9, -6) and (-2,-2)?
Choose 1 answer:

I NEED HELP I DONT UNDERSTAND!!

Answers

Answer:

Step-by-step explanation:

there is a formula for finding distance,

distance = sqrt [ ( x2-x1)^2 + (y2-y1)^2 ]

where point P1 = (-9.-6)  

    in the form of (x1,y1)

and point P2 = (-2,-2)  

 in the form of (x2,y2)

then

distance = sqrt [ (-2-(-9))^2 + (-2-(-6))^2 ]

distance = sqrt [ (-2+9)^2 + (-2+6)^2 ]

distance = sqrt [  [tex]7^{2}[/tex] + [tex]4^{2}[/tex] ]

distance = [tex]\sqrt{65}[/tex]

you can leave it in the form of  [tex]\sqrt{65}[/tex] because that's the most accurate , but also can make a close approximation with  8.062257748

B Reading Choose the best estimate for the multiplication problem below. 85 x 86
A. 8100
B. 10,400
C. 12,200​

Answers

Answer:

A. 8100

Step-by-step explanation:

85 x 86

To estimate, we multiply 85*100, which is the easiest multiplication, as a multiplication by 100 is the same as placing two zeros at the end of the number.

85*100 = 8500

Since 86 < 100, 85*86 < 8500. Thus, the correct estimate is given by option A.

Step-by-step explanation:

First you substitute in 5 for all of the x in the equation, making

Then you just have to simplify from there.

f(5) = -20 - 11

f(5) = -31

What is the range of possible sizes for side x?

Answers

Answer:

x = 3.96

Step-by-step explanation:

To find the missing side length you'll need the formula a^2 + b^2 = c^2

a and b would be the shorter ends, 2.8 and 2.8

c would be the longer end that's opposite the right angle.

so substitute values

2.8^2 + 2.8^2 = c^2

7.84 + 7.84 = c^2

15.68 = c^2

√15.68 = √c^2

3.959797 = c

c = 3.96

side c would be side x so x is 3.96

4 1/2 divied 1 5/8 please help

Answers

Answer:

36/13 (2 10/13)

Step-by-step explanation:

Convert 4 1/2 into an improper fraction: 4 1/2 = 9/2

Convert 1 5/8 to an improper fraction : 1 5/8 = 13/8

Divide: Dividing 2 fractions is the same as multiplying the first fraction by the reciprocal of the second value (the numerator becomes the denominator and the denominator becomes the numerator). 13/8 is 8/13 as a reciprocal. Next multiply the 2 numerators. 9 x 8 = 72. Then multiply the denominators. 2 x 13 = 26. Which gives 72/26. Divide both numbers by 2 which gives 36/13. 36/13 as a mixed number is 2 10/13

A bag hes 10 red marbles, 3 green marbles,
7 yelow marbles, and 5 blue merbles. What is
the probability of crowing a red marble and
then g, blue, marble without replacing the first?

Answers

Answer:

[tex]\frac{3}{5}[/tex]

Step-by-step explanation:

Probability is the chance of an event happening. One finds the probability of an event by using the following general formula,

[tex]\frac{desired}{total}[/tex]

In this case, the desired outcome is pulling whether a red or blue marble from the bag, the desired equals the sum of the number of red and blue marbles.

(red) + (blue)

= 10 + 5

= 15

The total number of marbles is the sum of all the number of marbles in the bag.

(red) + green)  + (yellow) + (blue)

= 10 + 3 + 7 + 5

= 25

Now substitute these values into the formula to find the probability, then simplify,

[tex]\frac{15}{25}[/tex]

Divide both the numerator and denominator by (5),

[tex]\frac{3}{5}[/tex]
