Answer:

He needs 92 on his last test.

Step-by-step explanation:

Mean score:

The mean is the sum of all scores divided by the number of tests.

In this question:

Scores of 85, 89, 85, 89 and x(the last one).

5 tests.

We want a mean of 88. So we find x for a mean of 88.

[tex]\frac{85 + 89 + 85 + 89 + x}{5} = 88[/tex]

[tex]348 + x = 440[/tex]

[tex]x = 440 - 348 = 92[/tex]

He needs 92 on his last test.

Answer:

B) x = (-5 + √10)/3 and (-5 - √10)/3 is the answer.

Step-by-step explanation:

3x² + 10x + 5 = 0

a = 3

b = 10

c = 5

Finding the Discriminant (D),

D = b² - 4ac

D = 10² - 4 × 3 × 5

D = 100 - 60

D = 40

√D = 2√10

Using quadratic formula,

x = (-b ± √D)/2a

x = (-b + √D)/2a

x = (-10 + 2√10)/2 × 3

Taking out the common factor 2,

x = (-5 + √10)/3

Similarly,

x = (-b - √D)/2a

x = (-10 - 2√10)/2 × 3

x = (-5 - √10)/3

Answer:

C. To control both unintentional research bias and participant prior beliefs

Step-by-step explanation:

Double blinding is a type of study where neither the participants nor the researchers know the treatment or intervention that the participants receive until the whole study/research is completed. This is very important because it means that the results gotten from the study have a very slim chance of being biased.

Thus,the correct answer is option C as it includes both the researcher and the participants

Answer:

Arithmetic

Step-by-step explanation:

Arithmetic is additive and geometric is multiplicative, and the numbers aren''t multiplying, they're adding.

Answer:

The solution is [tex]x = \frac{1}{2}[/tex]

Step-by-step explanation:

To solve this exponential equation, we must write both sides as powers of 3.

The equation given is:

[tex]3^{7x + 4} = (\frac{1}{27})^{x-3}[/tex]

Since [tex]3^3 = 27[/tex], we have that [tex]3^{-3} = \frac{1}{3^3} = \frac{1}{27}[/tex], so[tex]\frac{1}{27} = 3^{-3}[/tex]

Then

[tex]3^{7x + 4} = (\frac{1}{27})^{x-3}[/tex]

[tex]3^{7x + 4} = (3^{-3})^{x-3}[/tex]

[tex]3^{7x + 4} = 3^{-3(x-3)}[/tex]

[tex]3^{7x + 4} = 3^{-3x + 9}[/tex]

Since both sides are now powers of 3, we can equal them:

[tex]7x + 4 = -3x + 9[/tex]

[tex]10x = 5[/tex]

[tex]x = \frac{5}{10}[/tex]

[tex]x = \frac{1}{2}[/tex]

The solution is [tex]x = \frac{1}{2}[/tex]

Answer:

18 11/15

Step-by-step explanation:

This is the answer because:

1) First, find the common denominator: 12 1/3 = 12 5/15 and 6 2/5 = 6 6/15

2) Then add the fractions: 12 5/15 + 6 6/15 = 18 11/15

3) 18 11/15 is reduced to the lowest terms because 11 is a prime number.

Therefore, 18 11/15 is the answer.

Hope this helps! :)

Answer:

c. PROPOSITION ONE is false and PROPOSITION TWO is true

Step-by-step explanation:

In this question, we have that:

pvalue of 0.058

Significance level of 0.05

The pvalue is larger than the significance level, which means that there is no statistically significant association(Propostion One is false), and the null hypothesis is not rejected, that is, it is proved, so Proposition Two is true.

This means that the correct answer is given by option C.

Answer:

Christmas lights are price based shopping products

Step-by-step explanation:

From the question we understand that, Beth bought as many cheapest lights as possible. This means that she places value over quantity than quality.

The above is an illustration of price based shopping products where customers (in this case, Beth) see all products (in this case, Christmas lights) as similar products, irrespective of their different qualities (after all, they all light Christmas trees).

Because of this, the customer will opt for least expensive items, leaving the more expensive items.

juniors: 1170

sophomores: 975

freshmen: 585

Step-by-step explanation:

4 + 6 + 5 + 3 = 18

3510/18 = 195

195(4) = 780

195(6) = 1170

195(5) = 975

195(3) = 585

Answer:

Diagonal = 13 yd

Step-by-step explanation:

The diagonal of the 3D shape can be solved using the extension of the pythagorean theorem, which is given as: d² = a² + b² + c²

Where,

a = 12 yd

b = 3 yd

c = 4 yd

d = diagonal

Plug in the values

d² = 12² + 3² + 4²

d² = 169

d = √169

d = 13 yd

Answer:

25%

Step-by-step explanation:

28 to 46 consists of 1 whisker so that's 1/4

2 whiskers = 1/2 = 50%

The IQR = 1/2 = 50%

1/4 = 25%

Answer:

[tex]BE = 4\sqrt2[/tex]

Step-by-step explanation:

Given

The attached square

Required

Find BE

First, we calculate BD (the diagonal) using Pythagoras theorem.

[tex]BD^2 = BA^2 + AD^2[/tex]

Since the shape is a square, then

[tex]BA = AD = 8[/tex]

So:

[tex]BD^2 = 8^2 + 8^2[/tex]

[tex]BD^2 = 2(8^2)[/tex]

Take square roots

[tex]BD = \sqrt{2(8^2)[/tex]

[tex]BD = \sqrt{2} * 8[/tex]

[tex]BD = 8\sqrt{2}[/tex]

BE is half BD.

So:

[tex]BE = \frac{1}{2} * BD[/tex]

[tex]BE = \frac{1}{2} * 8\sqrt2[/tex]

[tex]BE = 4\sqrt2[/tex]

Answer:

Step-by-step explanation:

it's an unfair question b/c we have to know if it's out of all girls or out of all kids.  So we need to know the population total.   so if it was just girls the it's

3/45 = 0.0666666666666...

if it's out of kids.. then it's  3/123= 0.02439....

so that's the two choices.. which one is on the list of choices? both are so that's why this is an unfair question.  maybe this is more to the question not shown in the picture?  hmmmm

Step-by-step explanation:

Remark

I don't think you need the quadratic formula for this equation. It just factors into (b - 2)(b - 2), but I'll do it because you requested it.

Formula

[tex]\text{x = }\dfrac{ -b \pm \sqrt{b^{2} - 4ac } }{2a}[/tex]
