A company that makes hair care products at 7000 people trying to shampoo of the 7000 people 28 had a mild allergic reaction what percent of the people had a mild allergic reaction
Answer:
0.4%
Step-by-step explanation:
Given that:
Number of people with mild allergic reaction = 28
Total number of people = 7000
To find:
Percentage of people who have a mild allergic reaction to the shampoo = ?
Solution:
First of all, let us understand how can we calculate percentage of a particular amount.
Percentage of a particular amount can be calculated by dividing the amount with the total amount and then multiplying it with 100.
Percentage of [tex]p[/tex] from [tex]q = \frac{p}q\times 100[/tex]
Here,
[tex]p = 28\\q =7000[/tex]
Therefore, the percentage of people who have mild allergic reaction:
[tex]\dfrac{28}{7000}\times 100\\\Rightarrow \dfrac{2800}{7000} \\\Rightarrow 0.4\%[/tex]

Step-by-step explanation:
If you randomly choose two letters from the word "JANUARY ", find the probability that you choose letter J first and then A after replacing the first. Round answer to nearest tenth and include percent sign. Also, does this represent an independent or dependent scenario?
Answer:
2.0%
Step-by-step explanation:
The probability of two events happening in the sequence is calculated by multiplying the probability of each event happening separately by one another. Since there are a total of 7 letters in this word then the probability of choosing one letter correctly is [tex]\frac{1}{7}[/tex] . Since the first letter is replaced before choosing the second letter the probability remains the same. Therefore, the sequence would be the following...
[tex]\frac{1}{7} * \frac{1}{7}[/tex] = 0.020164 or 2.0%
This is an independent scenario because it does not depend on any external factors and under these circumstances the percentage will remain the same.

A scientist uses a submarine to study ocean life.
• She begins at sea level, which is at an elevation of o feet
• She travels straight down for 90 seconds at a speed of
3.5 feet per second
• She then travels directly up for 30 seconds at a speed of
2.2 feet per second
After this 120 second period, how much time, in seconds, will it take for the scientist to
travel back to sea level at the submarine's maximum speed of 48 feet per second?
Round your answer to the nearest tenth of a second.
Show your work
Answer:
5.2 seconds
Step-by-step explanation:
Traveling straight down: 90 * 3.5 = 315 feet down
Traveling up: 30 * 2.2= 66
315-66= 249
249/48= 5.1875 seconds
5.2 seconds <- rounded

A restaurant has 9 3/5 pounds of onions. The restaurant's manager ordered 4 4/5 more pounds of onions. The onions then were mixed and kept in 2 baskets with each basket having equal pounds on onions. How many pounds of onions does each basket contain?
Answer:
7 1/5 pounds in each basket
Step-by-step explanation:
Original pounds of onion = 9 3/5
New pounds of onion = 4 4/5
The onions then were mixed and kept in 2 baskets with each basket having equal pounds on onions
Total onions = Original pounds of onion + New pounds of onion
= 9 3/5 + 4 4/5
= 48/5 + 24/5
= 48+24/5
= 72 / 5 pounds
How many pounds of onions does each basket contain?
Pounds in each basket = Total pounds /2 basket
= 72/5 ÷ 2
= 72/5 × 1/2
= 72 / 10
= 7 2/10
= 7 1/5 pounds in each basket

PLS HELP!!! WILL GIVE BRAINLIST!!!!!
Answer:
number 3 maybe . sorry if wrong
Answer:
Slope is 20 and y-intercept is 40.
Step-by-step explanation:
First, let's find slope. I'll be using the points (1,60) and (3,100).
[tex]m=\frac{y2-y1}{x2-x1}=\frac{100-60}{3-1}=\frac{40}{2}=20[/tex]
So the slope is [tex]m=20[/tex]. Now we need to find y-intercept. We can do this by using our slope and a point in the point-slope equation, [tex]y=mx+b[/tex]. I'll use the point (1,60).
[tex]y=mx+b\\60=20(1)+b\\60=20+b\\b=40[/tex]
I hope this helps!

Step-by-step explanation:
Answer:
SAS
Step-by-step explanation:
I think it is SAS because it stands for Side-Angle-Side. The segment AD is congruent to itself because of reflexive property, so now you have two sides congruent and one angle congruent.

division property of equality 3n-5=-8(6+5n)
Answer:
n= - 1
Step-by-step explanation:
3n - 5 = -8(6+5n)
3n-5 = -48 - 40n
3n+40n = -48 + 5
43n = -43
n=-1
Joseph's lunch at a restaurant costs $13.00 without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax. What is the total cost of the lunch, including the tip
Answer:
The total cost of the lunch including the tip is $15.21.
Step-by-step explanation:
To find the total cost of the lunch including the tip, first, you need to calculate 17% of the price of the lunch as the statement indicates that that is the tip Joseph leaves the waiter:
$13*17%=$2.21
Now, you need to add that amount to the price of the lunch:
$13+$2.21=$15.21
According to this, the answer is that the total cost of the lunch including the tip is $15.21.

63 miles / hour = 0.0175 miles / secondStep-by-step explanation:
63 miles per hour also equals 0.0108225108225108 feet per second.
Which does not really help you if you don't know how to convert feet per second to miles per second.
How to convert miles per hour to miles per second is fairly easy, with a calculator.
1 mile per hour equals 0.000277777778 miles / second,
and if you multiply 0.000277777778 by 63, you get = 0.01750000001
Which can be rounded to get 0.0175

un rectangulo tiene 28 cm de perimetro y unos de sus lados mide 4 cm ¿cuantos cuadrados de 2 cm por lado se mecesitan para armar ese rectangulo
Answer:
10 cuadrados
Step-by-step explanation:
Si uno de los lados de rectangulo es de 4cm entonces el lado parallelo tambien es de 4cm. Eso nos da 8cm del perimetro y nos quedan los otros dos lados que tienen la misma medida. Entonces dividimos el resto del perimetro por 2.
28 - 8 = 20cm
20cm / 2cm = 10cm
Ahora que tenemos todas las medidas podemos multiplicar el largo por el ancho para calcular el area del rectangulo
10cm * 4cm = 40[tex]cm^{2}[/tex]
el cuadrado de 2cm tendra un area de
2cm * 2cm = 4[tex]cm^{2}[/tex]
Ahora simplemente dividimos el area del rectangulo por el area del cuadrado para saber cuantos cuadrados necesitamos para armar ese rectangulo
40[tex]cm^{2}[/tex] / 4[tex]cm^{2}[/tex] = 10 cuadrados
Tom can inflate 20 basketballs in 16 minutes . He concludes that if the total number of basketballs he can inflate, b, is proportional to the number of minutes
Answer:
Step-by-step explanation:
Step one:
given
we are told that tom can inflate 20 basketballs in 16 minutes
hence in one minute, he can inflate 20/16
= 10/8= 5/4 basketballs per minute
the rate at which he inflate the ball is 5/4 ball per minute.
The total number b is proportional to the number of minute
[tex]b\alpha t[/tex]
Tell whether the two rates form a proportion.
