Answer: 0.375

Step-by-step explanation:

Answer:

Yes.

Step-by-step explanation:

According to medical science, a body temperature considered normal (that is, below fever) in degrees Fahrenheit is 98ºF, while its equivalent in degrees Celsius is 36.6ºC. Therefore, a body temperature of 39ºC is higher than 98ºF, being equivalent to 102.2ºF.

This is verified by applying the conversion formula from Celcius to Fahrenheit:

(39 x 9/5) + 32 = X

39 x 1.8 + 32 = X

70.2 + 32 = X

102.2 = X

Answer:

B is the better detergent

Step-by-step explanation:

If A has a lower number on the 1-10 scale, that means on average it was closer to the lower end, or the least clean end. This means that A cleans worse than B., and B is better.

The two laundry detergents B cleans better.

Although the questions seems to be tricky at the begging because of a lot of numbers, but actually it is not.

Given to us in the question that, 25 pieces are randomly assigned to be cleaned with detergent A, and the remaining 25 pieces are cleaned with detergent B.

Thus, we can say that the sample size for both detergent A and detergent B is same. Also, the sample is distributed randomly meaning the sample is unbiased (fair).

Also, as given the mean rating for detergent A is found to be significantly less than the mean rating for detergent B. And we know that the mean is the average of a set of given numbers.

Therefore, we can conclude that if detergent A has a lower mean meaning, it has cleaned the clothes with less effectiveness as compared to detergent B.

Hence, Out of the two laundry detergents, B cleans better.

Answer:

$405

Step-by-step explanation:

Ramona went out with her 3 sisters, they spent $58 plus 9% tax on their meal. They also left 15% tip. If they divided up the bill evenly, how much did each of them spend?

[tex] \frac{58 + 58(9\% + 15\%)}{3} [/tex]

[tex] = \frac{58 + 58(0.09 + 0.15)}{3} [/tex]

[tex] = \frac{58 + 58 \times 0.24}{3} [/tex]

[tex] = \frac{58 + 13.92}{3} [/tex]

Answer:

For [tex]x \in\mathbb{C}[/tex]

[tex]x = -2i[/tex]

[tex]x = 2i[/tex]

[tex]x = 7[/tex]

Step-by-step explanation:

[tex]f(x)=x^3-7x^2+4x-28[/tex]

For [tex]f(x) = 0[/tex]

[tex]x^3-7x^2+4x-28 = 0[/tex]

We can easily factor the expression [tex]x^3-7x^2+4x-28[/tex] by grouping.

[tex]x^3-7x^2+4x-28 = (x^3-7x^2)+(4x-28) = x^2(x-7)+4(x-7) = \boxed{(x^2+4)(x-7) }[/tex]

Now we have

[tex](x^2+4)(x-7) = 0[/tex]

Therefore,

[tex]x^2+4 = 0 \text{ or } x-7 = 0[/tex]

So,

[tex]x^2 = -4 \implies x = \pm\sqrt{-4}[/tex]

Once [tex]\sqrt{-1} = i[/tex]

[tex]x = \pm\sqrt{-4} = \pm\sqrt{4}\sqrt{-1} = \pm 2i[/tex]

Where is the picture I don't see it

Answer:

x=25

y= 64.5

Step-by-step explanation:

When lines are parallel, 2x=2(the number)

But, 2 isn't an angle.  However, 50degrees is congruent to 2 since they are verticle angles.

2x=50

x=25

When lines are parallel, 2y+1=1(the number)

But, 1 doesn't have a verticle angle.  However, 180-50 would be equal to 1

180-50=2y+1

130=2y+1

129=2y

y= 64.5

Answer:

[tex]3k - 4 > 60 - k \\ = 3k + k > 60 + 4 \\ = 4k > 64 \\ = k > \frac{64}{4} \\ = k > 16[/tex]

Answer:

k  > 16

Step-by-step explanation:

Solve it like an equation solving for k

Move the -4 to the other side by adding it to both sides.

3k -4 plus 4  > 60 plus 4 - k

You get 3k > 64 - k

now move the k from the right to the left by adding both sides by k

3k plus k > 64 - k  plus k

You get 4k > 64

Now divide both sides by 4 so you get k alone on one side to solve for the inequality

4k/4 > 64/4

k  > 16

Step-by-step explanation:

Answer:

She should go with service 2 because it is, cheaper. Service 1 cost $107.52, but service 2 cost only $105.

Step-by-step explanation:

Cost now+increase$=new cost

(Part=percent*whole)

Increase=percent increase*cost now

i=12%*$96

i=0.12*96=$11.52

$96+11.52=107.52

Service two⬇️

8.72*12=$105

Yes Clare should switch to service 2 because; cheaper it costs only $105 which is lesser than $107.52

To find the new cost, we will use the expression;

New Cost = Present Cost + increase

However,

Increase = percentage increase * present cost

Increase = 12% * $96

Increase = 0.12 * 96

Increase = $11.52

Thus;

New Cost  = $96 + 11.52

New Cost = $107.52

For Service two;

We are told that digital streaming costs $8.75 per month. Thus;

Cost = 8.75 * 12

Cost = $105
