A company that makes hair care products at 9000 people try a new shampoo. Of the 9000 people, 18 had a mid allergic reaction. What percent of the people had a mid allergic reaction

Answers

Answer 1

Answer:

0.2% of the people had mid allergic reaction.

Step-by-step explanation:

Given that:

Number of people tested for a new shampoo = 9000

Number of people who had allergic reaction = 18

Percent of people = [tex]\frac{People\ who\ have\ reaction}{Total\ number}*100[/tex]

Percent of people = [tex]\frac{18}{9000}*100[/tex]

Percent of people = 0.002 * 100

Percent of people = 0.2%

Hence,

0.2% of the people had mid allergic reaction.

What is the value of 15 + x2 when the value of x is 3? also there's a tiny 2 above the 15

Answers

Answer:

231

Step-by-step explanation:

So the tiny 2 above the 15 means 15 is squared

15 squared = 225

225 + x(2)

If x = 3, then simply plug that into the equation

225 + 3(2)

225 + 6

4). [tex]-\frac{27}{28}[/tex]

5). Amount payable by the customer = 1416 Rs.

Step-by-step explanation:

4). [tex](\frac{3}{7})\times (-\frac{5}{8})\div (\frac{1}{3}\times \frac{5}{6})[/tex]

   = [tex](-\frac{15}{56})\div (\frac{5}{18})[/tex]

   = [tex](-\frac{15}{56})\times \frac{18}{5}[/tex]

   = [tex]-\frac{54}{56}[/tex]

   = [tex]-\frac{27}{28}[/tex]

5). Cost of the item = Rs 1200

   G.S.T. applicable on this item = 18%

   Amount to be paid for G.S.T.= 1200 × [tex]\frac{18}{100}[/tex]

                                                   = Rs 216

What is the domain of the function shown on the graph?

Answers

Answer:

The domain of the graph is:

-∞ <  x < ∞

Hence, option B is correct.

Step-by-step explanation:

We know that the domain of the function is the set of input or arguments for which the function is real and defined.

In other words,

Domain refers to all the possible sets of input values on the x-axis.

From the given graph, we can easily observe that the graph extends horizontally to the left without bound, as well as to the right without bound.

Therefore, the domain of the graph is:

-∞ <  x < ∞

Hence, option B is correct.

Earning (y) : ____ 5 ____ 10 ____ 15 ____ 20

Boxes sold (x) :__ 2 ____ 4 _____ 6 ____ 8

Answer:

$2.5

Step-by-step explanation:

Given:

Earning varies directly as the number of boxes of cookies sold

y α x

y = kx - - - (1)

k = constant of proportionality (earning per box of cookies sold)

Taking any 2 points :

y = 10 ; x = 4

10 = k4

10 = 4k

Divide both sides by 4

10/4 = 4k/4

2.5 = k

Hence, the amount earned per box of cookies sold is $2.5

The force, F newtons, exerted by a magnet on a metal object is inversely
proportional to the square of the distance d cm.
When d = 2 cm, F= 50 N.
Express F in terms of d.

Answers

Answer:

F = 200/d^2

Step-by-step explanation:

F is inversely proportional to d^2

The equation is;

F = k/d^2

K = F•d^2

so to get k, we substitute the given values

K = 50 * 2^2

K = 50 * 4

K = 200

So we have that;

F * d^2 = 200

F = 200/d^2

what is the quotient (3x^2 + 8x -3) divided by (x + 3)

Answers

Answer:

Quotient = (3x-1)

Step-by-step explanation:

we need to find the quotient when (3x² + 8x -3) is divided by (x+3)

It means we need to divide (3x² + 8x -3) by (x+3).

We can write it as follows :

[tex]\dfrac{3x^2 + 8x -3}{(x+3)}[/tex]

Applying middle term splitting on the numerator.

[tex]\dfrac{3x^2 +9x-x-3}{(x+3)}\\\\=\dfrac{3x(x+3)-1(x+3)}{(x+3)}\\\\=\dfrac{(3x-1)(x+3)}{(x+3)}\\\\=(3x-1)[/tex]

So, the required quotient is (3x-1)

Answer: 6 problems in 4 minutes

Step-by-step explanation: If there are 45 problem and she can do them in 30 minutes, then you divide 45 by 30 to see how many problems she can do in one minute. 45 problems/30 minutes = 1.5 problems per minute. Then, you multiply 1.5 by 4, because you need to see the 4 minute mark, and 1.5 x 4 = 6. So, your answer is 6 problems.

In the second one (y, 9, 12, 15, 18) it goes up by 3 each time so y = 9-3 = 6.

the ratio of the heights of two similar pyramids is 2:5 in the volume of the smaller pyramid is 100 cubic feet, find the volume of the large pyramid ​

Answers

Volume is a cubic measurement.

Set up a ratio of volume to the ratio of the height:

100/v2 = 2^3/5^3

V2 = 100 x 5^3/2^3 = 100 x 125/8 = 1,562.5 cubic feet

The volume of large pyramid is 1,562.5 cubic feet, by using ratio of heights.

Volume of pyramid based problem:

What information do we have?

Ratio of heights of two similar pyramids = 2:5

Volume of smaller pyramid = 100 cubic feet

Volume of smaller pyramid / Volume of large pyramid = Height of smaller pyramid³ / Height of large pyramid³

100 / Volume of large pyramid = 2³ / 5³

Volume of large pyramid = 125(100) / 8

Volume of large pyramid = 1,562.5 cubic feet
