Which property is used in the statement?

nignag [31]

Its D . Subtraction property of equation

Let me show you why

p+5-8

Subtract 5 from both sides

p+5-5=-8-5

p=-13

So , yeah its D

During the basket ball season, morgan made 3 times as many 2 point baskets as she made 3 point baskets and free throws combined.

pogonyaev

Answer: Morgan make (66) 2point baskets.

Explanation:

It is given that during the basketball season, morgan made 3 times as many 2 point baskets as she made 3 point baskets and free throws combined.

Let the number of 2point basket be x, the number of 3point basket be y and the number of free throws be z.

$x=3(y+z)$

If she made 14 free throws and eight 3point baskets, then the number of 2point did she make is,

$x=3(14+8)$

$x=3(22)$

$x=66$

Therefore, the number of 2point baskets make by morgan is 66.

katie has red 32% of a book if she has to read 80 pages how many more pages does Katie have left to read

galben [10]

In this question, the information that Katie has already read 32% of a book that has a total of 80 pages is of great importance. This information is enough to find the required answer to the question.
Total number of pages Katie has to read = 80
Percentage of pages that Cathie read = 32%
Number of pages that Katie read = (32/100) * 80
   = 256/10
   = 25.6 pages
Then
The number of pages that Katie have left to read = 80 - 25.6
   = 54.4 pages
So Katie has 54.4 pages left to read.

An article includes the accompanying data on compression strength (lb) for a sample of 12-oz aluminum cans filled with strawberr

Veseljchak [2.6K]

Answer:

The calculated value |t| = 2.375 > 2.1009 at 0.05 level of significance

Null hypothesis is rejected 

Alternative hypothesis is accepted

The extra carbonation of cola results in a higher average compression strength

Step-by-step explanation:

Step(i):-

Given data

First sample size (n₁) = 10

mean of the first sample(x₁⁻) = 537

standard deviation of the first sample (S₁) = 22

second sample size (n₂) = 10

mean of the second sample (x₂⁻) = 559

standard deviation of the second sample (S₂) = 17

Step(ii):-

Null hypothesis : H₀:- The extra carbonation of cola results in a lower average compression strength

Alternative Hypothesis :H₁

The extra carbonation of cola results in a higher average compression strength

Step(iii):-

By using student's t -test for difference of means

Test statistic

  $t = \frac{x^{-} _{1}-x^{-} _{2} }{\sqrt{S^{2} (\frac{1}{n_{1} }+\frac{1}{n_{2} } } )}$ 

 where 

  $S^{2} = \frac{n_{1}S^{2} _{1} + n_{2} S_{2} ^{2} }{n_{1}+n_{2} -2 }$ 

  $S^{2} = \frac{10(22)^{2} + 10 (17) ^{2} }{10+10 -2 } = \frac{ 7730}{18} = 429.4$ 

  $t = \frac{537-559 }{\sqrt{429.4 (\frac{1}{10 }+\frac{1}{10 } } )}$ 

 t = -2.375

|t| = |-2.375| = 2.375

Degrees of freedom

γ = n₁+n₂ -2 = 10+10-2 =18

 $t_{\frac{\alpha }{2} ,n-1}=t_{(\frac{0.05}{2} ,18)} = t_{(0.025,18)}}=2.1009$ 

The calculated value |t| = 2.375 > 2.1009 at 0.05 level of significance

Null hypothesis is rejected 

Alternative hypothesis is accepted

Final answer:-

The extra carbonation of cola results in a higher average compression strength
