Answer 1

Answer:

24.4 > 24.34

Step-by-step explanation:

Tenth place value can be any number more than the tenth value in 24.34.

In the decimal number 24.34, the tenth value is 3. So, it should be more than 3

Options can be any one of these

24.4 or

24.5 or

24.6

Answer 2

Answer:

Values (tenths) that would make the number comparison 24._ > 24.34 true would be:
- 4
- 5
- 6

24.40 > 24.34
24.50 > 24.34
24.60 > 24.34

All other options provided would make the left side of the comparison less than the right side of the comparison.

A researcher wants to determine whether or not a five-week crash diet is effective over a long period of time. A random sample of 15 dieters is selected Each person's weight is recorded before starting the diet and one year after it is concluded. Based on the data shown at right (weight in pounds), Can we conclude that the diet has a long-term effect, that is, that dieters manage to not regain the weight they lose? Include appropriate statistical evidence to justify your answer.

Answers

Using the t-distribution, as we have the standard deviation for the sample, it is found that it cannot be concluded that the diet has a long-term effect.

What are the hypotheses tested?

At the null hypotheses, it is tested if there is no difference in the weights, that is:

[tex]H_0: \mu_A - \mu_B = 0[/tex]

At the alternative hypotheses, it is tested if the weights decrease, that is:

[tex]H_1: \mu_A - \mu_B < 0[/tex]

What is the mean and the standard deviation of the distribution of the difference?

Using a calculator, for each sample, we have that:

[tex]\mu_B = 210.8, s_B = 33.85, sE_B = \frac{33.85}{\sqrt{15}} = 8.74[/tex]

[tex]\mu_A = 207.2, s_A = 33.47, sE_A = \frac{33.47}{\sqrt{15}} = 8.64[/tex]

Hence, for the distribution of differences, we have that:

[tex]\overline{x} = \mu_A - \mu_B = 207.2 - 210.8 = -3.6[/tex]

[tex]s = \sqrt{sE_B^2 + sE_A^2} = \sqrt{8.74^2 + 8.64^2} = 12.3[/tex]

What is the test statistic?

It is given by:

[tex]t = \frac{\overline{x} - \mu}{s}[/tex]

In which [tex]\mu = 0[/tex] is the value tested at the null hypothesis.

Then:

[tex]t = \frac{\overline{x} - \mu}{s}[/tex]

[tex]t = \frac{-3.6 - 0}{12.3}[/tex]

[tex]t = -0.29[/tex]

What is the decision?

Considering a left-tailed test, as we are testing if the mean is less than a value, with a standard significance level of 0.05 and 15 + 15 - 2 = 28 df, the critical value is of [tex]t^{\ast} = -1.7[/tex].

Since the test statistic is greater than the critical value for the left tailed test, it cannot be concluded that the diet has a long-term effect, as the null hypothesis is not rejected.

Problem 8

Answer: angle LSO and angle MSN

--------------

Explanation:

Vertical angles form when we intersect two line segments, lines, or rays. Vertical angles are opposite one another and they are always congruent.

=============================================

Problem 9

Answer: angle LMS and angle SMN

--------------

Explanation:

Adjacent angles share a common line, line segment, or ray. Think of two adjacent rooms sharing a common wall between them. In the case of the answer above, the two angles share the common segment SM (note how S and M are part of LMS and SMN)

When it comes to naming angles, the middle letter is always the vertex of the angle. This is the hinge so to speak. Or you could picture a pair of scissors. For angle LMS, the arms LM and SM are the two blades of the scissors while point M is where the blades meet.

=============================================

Problem 10

Answer: angle LSM and angle MSN

--------------

Explanation:

Same idea as problem 9. Now we're making S the middle letter. Something like angle LSM is the same as angle MSL.

In this case, the two adjacent angles form a straight line. We consider these two angles a linear pair.

Solve the inequality. 5+5(-7x+ 1) ≥ -130 write answer in the format variable inequality number

Answers

Answer:

x<_ 4

Step-by-step explanation:

first you distribute 5 to equal 5-35x+5 then you would carry the non variables to one side to be -35x>_-140 and the you would flip the sides because te variable is negative so it would be -35x<_ -140 the divid to get x<_4

Answer: x is less than or equal to 4

Distribute -5
5+-35x+5>-130

Combine like terms
10+-35x>-130

Subtract 10 from both sides
-35x>-140

Divide by -35 on each side
(Flip the sign since you divide by a negative)

-35x/35 > -140/35

What is the slope of the equation y= 5/4 times -7/4

Answers

Answer:

5/4

Step-by-step explanation:

If the equation is

[tex] y = \dfrac{5}{4}x - \dfrac{7}{4} [/tex]

then the slope is the number multiplying x, so

slope = 5/4.

Answer:

5/4.

The x is a variable, not a multiplication sign.

The equation is

y=mx+b

the slope is the m.

Plz i need help urgently I’ll mark brainiest the sum of a number, two thirds of the number and a quarter number of the number gives 5 3/4, find the number

Answers

Step-by-step explanation:

so you have to make an equation where you let x=the number, so it would be

x+(2/3)x+(1/4)x=5 3/4

you combine the like terms to get

(23/12)x = 5 3/4

multiply both sides by the reciprocal of 23/12 to isolate x, and you're left with

x=36/92, which simplifies to 9/23.

Answer:

2. 180cm³

3. 600ft³

4. 360cm³

5. 312cm³

6. 15.6kg

7. 1.95kg

Step-by-step explanation:

1: V = Bh = (7x3)x4 = 84in³

2: V = Bh = 1/2(8x5) x 9

= 20 x 9

= 180cm³

3: V = Bh = 1/2(b1+b2) h x 5

= 1/2(20+10) 8 x 5

= 15 x 8 x 5

= 15 x 40

= 600ft³

4: V = Bh = 1/2 (4x9) x 20

= 18 x 20

= 360cm³

5: Total volume = Volume of rectangular prism + Volume of triangular block

= (8.5 x 4 x 9) + 1/2(1.5 x 2) x 4

= 306 + 6

= 312cm³

6: divide 312cm³ by 20kg/cm³ to get the approx. mass:

312/20 = 15.6kg

7: first find the volume of the friends Display:

= (4.25 x 2 x 4.5) + 1/2(0.75 x 1) x 2

= 38.25 + 0.75

= 39cm³

Now divide by 20 to find the approx. weight of the friends display:

39/20 = 1.95kg

Tiana has 2 2/3 gallons of paint. She uses 1/2 of the total amount to paint her room. She gives of the remaining paint to her brother. How many gallons of paint does Tiana give to her brother?

Answers

Answer:

2 1/6

Step-by-step explanation:

How we calculate this is make the two fractions denominators the same so we can make them both 6.

for the 3 we times it by 2 and 2 by 3.

so our 2 fractions are now 2 4/6 and 3/6 Now

so if we take away 3 of 4 we get 1 so 2 and 4/6 is now 2 and 1/6

Meaning the 2 1/6 is what she has left so if she gives that all to her brother he gets that and there's your answer.

what does x equal in the equation [tex]\frac{3}{5}x- \frac{1}{4}x=7\\[/tex]

Answers

Answer:

[tex] x = 20 [/tex]

Step-by-step explanation:

[tex] \frac{3}{5}x - \frac{1}{4}x = 7 [/tex]

The LCD is 20, so multiply both sides of the equation by 20.

[tex] 20(\frac{3}{5}x - \frac{1}{4}x) = 20 \times 7 [/tex]

[tex] 4 \times 3x - 5 \times x = 140 [/tex]

[tex] 12x - 5x = 140 [/tex]

[tex] 7x = 140 [/tex]

Kirsten is trying to find height using the volume of a cylinder formula, V=πr2⋅h . Which of the following would be a good first step in re-arranging the formula to isolate the height? A) divide both sides of the equation by h B) multiply both sides of the equation by r C) divide both sides of the equation by π D) multiply both sides of the equation by h

Answers

Answer:

Step-by-step explanation:

we want to "isolate" h (height). that means "h" needs to be alone on one side of the equation, and all other factors need to be brought to the other side.

so, yes, we need to divide both sides by all factors of h : pi and r². only then will we have the isolated h on one side.

therefore, dividing both sides by pi is a good first step.
