Step-by-step explanation:
two chips are drawn at random and withoit replacement from a bag containing four blue chips and three red chips. find the probability of drawing two red chips.
The probability of getting two red chips is:
P = 1/21.
How to get the probability?
The probability of getting a red chip is equal to the quotient between the number of red chips and the total number of chips.
There are 4 blue chips and 3 red chips, for a total of 7 chips.
For the first draw, the probability of getting a red one is:
p = 3/7.
For the second draw, now there are 2 red chips and 6 chips in total, so now the probability is:
q = 2/6 = 1/3
Then the joint probability, given by the product between the two individual probabilities, is:
P = q*p = (3/7)*(1/3) = 1/21.

The linear function that has a different rate of change from y = -3x+4 is A, a function with a y-intercept of -4 that passes through the point (-3,-13)
What is an intercept?An intercept is the point where a straight line or a curve meets with the x or y axes.
Analysis:
The rate of change is the same as slope. The slope of y = -3x + 4 is -3,
All other functions Except A have a slope of -3.
for linear function A,
if y = mx + c, c = -4, x = -3, y = -13
-13= -3m - 4
-3m = -9
m = 3
In conclusion, linear function A with a y-intercept of -4 passing through the point (-3,-13) has a different rate of change from y = -3x + 4

PROBLEMS
1) Add the following: 30 mg, 2.5 kg and 7.0 g. Express the answer in g.
2) Express the amount of 1.243 g as:
mg ________
kg ________
mcg _______
3) How many grams of the active ingredient "aspirin" would be needed to make 500 aspirin tablets if each tablet must contain 325 mg?
Answer:
1. 2507.034 g
2. 1243mg
0.001243kg
1,243,000 mcg
3. 162.5g
Step-by-step explanation:
1. First of all we need to convert 30mg and 2.5kg to gram.
⇒ 1 gram = 1000 milligrams
x = 35mg
⇒ 1000mg(x) = 35mg
⇒ x = 35mg = 35 = 0.035g
1000mg 1000
Next we convert 2.5kg to gm.
⇒ 1 kilogram = 1000g
2.5kg = x
(We then criss cross)
⇒ x = 2.5kg × 1000g = 2500g = 2500g
1kg 1
Now that we converted them all to gram, we will add them.
⇒ 30mg + 2.5kg + 7g = 0.035g + 2500g + 7g = 2507.035 ≈ 2507g
2. We convert 1.234g into
a. mg
⇒ 1 gram = 1000 milligram
1.243g = x
⇒ x = 1.243g × 1000mg = 1243mg = 1243mg
1g 1
b. kg
⇒ 1 kilogram = 1000gram
x = 1.243 gram
⇒ x = 1.243g × 1kg = 1.243kg = 0.001243kg = 1.243 × 10⁻³ kg
1000g 1000
c. mcg
⇒ 1 gram = 1000000mcg
1.243g = x
⇒ x = 1.243g × 1,000,000mcg = 1,243,000mcg = 1,243,000mcg
1 g 1
3. We need 500 aspirin, the amount of grams needed and we know that one tablet contains 325mg.
So now we can derive the formula such that:
⇒ 1 tablet = 325mg
500 tablet = x
But first we need to convert 325mg to grams.
⇒ 1 gram = 1000mg
x = 325mg
⇒ x = 325mg × 1 g = 325g = 0.325g
1000mg 1000
So now instead of using 325mg we can use 0.325g.
⇒ 1 tablet = 0.325g
500 tablets = x
⇒ x = 500 tablets × 0.325g = 162.5g = 162.5g
1 tablet 1

[tex]\\ \rm\Rrightarrow sin52=\dfrac{9.2}{B C}[/tex]
[tex]\\ \rm\Rrightarrow B C=\dfrac{9.2}{sin52}[/tex]
[tex]\\ \rm\Rrightarrow B C=9.3[/tex]
Answer:
11.7 (3 s.f.)
Step-by-step explanation:
Given information:
∠CAB = 90°∠ABC = 52°AC = 9.2As one of the given angles is 90°, the triangle is a right triangle.
Draw the triangle using the given information (see attached) to help visualize the problem.
To calculate the length of BC, use the sine trigonometric ratio:
[tex]\sf \sin(\theta)=\dfrac{O}{H}[/tex]
where:
[tex]\theta[/tex] is the angleO is the side opposite the angleH is the hypotenuse (the side opposite the right angle)From inspection of the attached triangle:
[tex]\theta[/tex] = 52°O = AC = 9.2H = BCSubstitute the values into the formula and solve for BC:
[tex]\implies \sf \sin(52^{\circ})=\dfrac{9.2}{BC}[/tex]
[tex]\implies \sf BC=\dfrac{9.2}{\sin(52^{\circ})}[/tex]
[tex]\implies \sf BC=11.67496758...[/tex]
[tex]\implies \sf BC=11.7\:\:(3 \:s.f.)[/tex]
Therefore, the length of BC is 11.7 (3 s.f.).

In the diagram, points D and E are marked by drawing arcs of equal size centered at B such that the arcs intersect and . Then, intersecting arcs of equal size are drawn centered at points D and E. Point P is located at the intersection of these arcs.
Based on this construction, m∠ABP is
°, and m∠ABC is
°.
The measure of ∠ABP and ∠ABC are 32° and 64° respectively.
what is a bisector of an angle?Any line which divides an angle into two equal halves is a bisector of that angle.
Analysis:
Since the arcs at D and E are drawn with the same radius and arc using center D and E are intersected by line PB( which is the bisector of the full arc with center B) then ∠ABP = ∠PBC = 32°.
∠ABC = ∠ABP + ∠PBC
∠ABC = 32 + 32 = 64°
In conclusion, ∠ABP and ∠ABC are 32° and 64°

18. The desired density of the shaved ice is 0.697 g/cm3, and the cost, per kilogram, of ice is $3,83. Determine
and state the cost of the ice needed to make 50 snow cones.
The cost of the ice needed to make 50 snow cones is $54.50.
What is cost of the ice?The first step is to determine the volume of the snow cone.
Volume of the snow cone =volume of a cone + volume of the hemisphere
Volume of the cone = 1/3πr²h
1/3 x 3.14 x 10.2 x (8.3/2)² = 183.87 cm³
Volume of the hemisphere = 2/3πr³
2/3 x 3.14 x (8.3 / 2)³ = 224.43 cm³
Total volume = 224.43 cm³ + 183.87 cm³ = 408.30 cm³
Volume of 50 snow cones = 408.30 cm³ x 50 = 20,414.82
Total grams of ice needed = density x volume
0.697 x 20,414.82 = 14,229.13 grams
Convert gram to 1kg
1kg = 1000g
= 14,229.13 grams / 1000 = 14.23kg
Cost of the ice = 14.13 x 3.83 = $54.50
