Answer:
0.4 = 40% of this group likes chocolate
Step-by-step explanation:
Conditional Probability
We use the conditional probability formula to solve this question. It is
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]
In which
P(B|A) is the probability of event B happening, given that A happened.
[tex]P(A \cap B)[/tex] is the probability of both A and B happening.
P(A) is the probability of A happening.
In this questions:
Event A: Likes sprinkles
Event B: Likes chocolate.
20% of your friends like sprinkles (S) topping.
This means that [tex]P(A) = 0.2[/tex]
8% of your friends like Chocolate (C) and also like sprinkles (S).
This means that [tex]P(A \cap B) = 0.08[/tex]
Of the friends who like sprinkles, what proportion of this group likes chocolate?
[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.08}{0.2} = 0.4[/tex]
0.4 = 40% of this group likes chocolate
I bought a pack of 100 rectangular index cards. Each card measured 15 cm by 10 cm. The pack said: paper density=200gsm (grams per square metre). This means that a square metre of these cards weighs 200 g.
Each pack of cards is wrapped in a sheet of 50GSM paper with an area of 800cm^2. I have a number of packs and wish to store them on a shelf which cannot hold more than 10kg. What is the largest whole number of wrapped pack that can be stored?

Expression A: (2k + 8) + (5k + 10)
Expression B: 76 + 18
Are the two expressions equivalent?
A. No, because for k = 3, the value of Expression A is 29 and the value of Expression B is 39.
B. Yes, because for k= 3, the value of Expression A is 75 and the value of Expression B is 75.
C. Yes, because for k= 3, the value of Expression A is 39 and the value of Expression B is 39.
D. No, because for k= 3, the value of Expression A is 39 and the value of Expression B is 75.

Answer:

Step-by-step explanation:
Scientists once thought that life spontaneously arose from nonliving things. It took extensive experimentation and the invention of new technology to confirm the tenets that now make up the cell theory. Now, we don't even question that cells are the basic units of life and only come from preexisting cells. What technology had the biggest impact on the development of the cell theory?
centrifuge
electrophoresis
microscope
telescope
The technology had the biggest impact on the development of the cell theory is microscope. Hence, option C is correct.
What is cell?The fundamental units of all living organisms are cells. There are many billions of cells in the human body. They give the body structure, absorb nutrients from meals, turn those into energy and perform certain tasks. Additionally, cells have the ability to replicate themselves and contain the body's genetic material.
Each component of a cell has a different purpose. These components include organelles, which are specialized structures that carry out specific functions for the cell.
A cell's nucleus acts as its command center, giving instructions on how to develop, develop, divide, or die. The cell's genetic material, DNA (deoxyribonucleic acid), is also stored there. The envelope, which encircles the nucleus and divides it off from the rest of the cell, shields the DNA and serves as a barrier.

You are given the results of measurements of sizes of a crushed stone for road
construction. The technical requirement is the following: The mean size of the stones must be in the interval [33-36] mm and standard deviation must be smaller than 6 mm. Will this batch pass the technical control?
Answer:
The standard deviation is above 6 mm, which means that this batch does not pass the technical control.
Step-by-step explanation:
Mean of the batch:
The mean of the batch is the sum of all values divided by the number of items. So
[tex]M = \frac{31+32+38+34+45+41+24}{7} = 35[/tex]
Mean in the desired interval.
Standard deviation:
Square root of the sum of the difference squared between each term and the mean, divided by the number of itens. So
[tex]S = \sqrt{\frac{(31-35)^2+(32-35)^2+(38-35)^2+(34-35)^2+(45-35)^2+(41-35)^2+(24-35)^2}{7}} = 6.46[/tex]
The standard deviation is above 6 mm, which means that this batch does not pass the technical control.

If x: y = 7:8 and y: z = 9:10, find x:y:z
9514 1404 393
Answer:
x : y : z = 63 : 72 : 80
Step-by-step explanation:
We can make the y-value the same by multiplying the first proportion by 9 and the second by 8.
x : y = 63 : 72
y : z = 72 : 80
Now, we can write ...
x : y : z = 63 : 72 : 80

(16x) °
А
С
What is the measure of the exterior angle at C?
PLS HELP
Answer:
measure of exterior angle at C = 160°
Step-by-step explanation:
An exterior angle of a triangle equals the sum of the two remote interior angles
A and B are the remote interior angles. So,
m∠A + m∠B = measure of exterior angle at C
5x - 10 + 12x = 16x
17x - 10 = 16x
x = 10
measure of exterior angle at C = 16x = 16(10) = 160°

Negative
Positive
Answer:

Step-by-step explanation:
it will be -2 because 6 cannot be taken out of 4, when looking on a number line if you move your point six points to the left (because it is minus six) of 4 you will end up at negative two. Any equation that is subtracting a number bigger than itself will be negative.

Identity- An equation that is true for all real numbers for which both sides are defined is called a(n) Identity
Step-by-step explanation:
It called identity. Identity equations are conditions that are genuine regardless of what esteem is connected to for the variable. On the off chance that you rearrange a personality condition.
What is real numbers?Real numbers are just the numbers on the number line. It is the easiest way to think of them. Basically, if you can put the number in question on an infinitely big number line, then it is a real number.
It called identity. Identity equations are conditions that are genuine regardless of what esteem is connected to for the variable. On the off chance that you rearrange a personality condition.
An identity is a balance that remains constant paying little respect to the qualities decided for its variables. They are utilized as a part of streamlining or reworking polynomial math articulations. By definition, the two sides of a character are tradable, so we can supplant one with the other whenever.

Step-by-step explanation:
what is the formula for the whole surface area of a sphere ?
[tex]a = 4 \times \pi \times {r}^{2} [/tex]
that would give us the whole surface area all 360 degrees or 2×pi arc length all around the sphere.
but we don't need all 360 degrees. we only need the Theta'th (that is the specified angle) part.
in radians the arc length of that angle segment on the "equator" of the sphere
s = r×Theta
and the whole equator circumference is
c = 2×pi×r
so, the Theta'th part is then
r×Theta / 2×pi×r = Theta / 2×pi
we only need that part of the whole sphere surface area, so the formula would look like
[tex]lune = theta \times 4 \times \pi \times {r}^{2} \div (2 \times \pi)[/tex]
=>
[tex]lune = theta \times 2 \times {r}^{2} [/tex]
