Find the slope given the following two points: (16,3) and (14, -19)
Answers
Answer:
the slope m=11
Step-by-step explanation:
(To find the slope use the equation m=[tex]\frac{y2-y1}{x2-x1}[/tex])
(16,3), where 16=x1 and 3=y1
(14,-19), where 14=x2 and -19=y2
m=[tex]\frac{y2-y1}{x2-x1}[/tex]
=[tex]\frac{-19-3}{14-16}[/tex]

Given f(x) = -x + 7, find x when f(x)= -4
Answers
Answer:
x = 11
Step-by-step explanation:
f(x) = -x + 7
f(x) = -4
Using substitution, -x + 7 = -4
Then you can solve from there
-x + 7 = -4
-x = -11
x = 11

It takes 12.5g of kool-aid powder to make 5 liters of juice. How many grams of powder will it take to make 20.5 liters of juice? pls answer quick its due in 15 mins
Answers
Answer:
8.2
Step-by-step explanation:
Sorry man, A bit late : l but here it is anyways...
12.5g of kool-aid power can make 5 liters of juice.
20.5g liters of juice can make ? liters of juice.
Think of it as a ratio!
12.5:5 and 20.5:?
what times what equals to what?
12.5/2.5=5 SO, you do 20.5/2.5= 8.2
That's your answer! Hope you get it right!
Answer:
51.25 grams
Step-by-step explanation:
Alright so, in this question you need to figure out what is the amount for 1 liter. We can figure this out by doing 12.5 ÷ 5.
That equals to 2.5 grams. Great, now we have figured out the amount for 1 liter. The next step is pretty self explanatory. We multiple 2.5 grams x 20.5 and that equals to 51.25 grams needed.
Mathamatical explanation:
12.5g ÷ 5L
= 2.5g
2.5g x 20.5L
= 51.25grams

students at Freeman Middle School have a choice of water milk or juice for breakfast from a survey it was determined that 50 students prefer water 100 prefer juice and 150 prefer milk. you want to know the probability that exactly 3 of 4 randomly selected students do not prefer water how could you model the scenario? This scenario can be simulated by Rolling a six-sided die (A 3 B 4 C 5 D 6 E 7 times). The (A numbers 0 to 3 B numbers 0 to 6 C number 1 D numbers 7 to 9 ) would represent students who prefer water if a number (A 0 to 3 B 0 to 6 C 1 D 7 to 9) appears only once in a set of outcomes then it will mean that three of four randomly picked students do not prefer water in that set .
Answers
Answer:
The probability that exactly three of four randomly selected students that do not prefer water is; P=125/1296= 0.096
Step-by-step explanation:
Hope this helps
The required probability that exactly 3 of 4 randomly selected students do not prefer water is 0.096.
Given that,
Students at Freeman Middle School have a choice of water milk or juice for breakfast.
From a survey, it was determined that 50 students prefer water 100 prefer juice, and 150 prefer milk.
Probability can be defined as the ratio of favorable outcomes to the total number of events.
the probability that selected students to prefer water.
Total sample space = 300
Total desired events = 50
Pw = 50 / 300 = 1/6
the probability that selected students do not prefer water
Total sample space = 300
Total desired events = 100+150 = 250
Pmj = (250)/300
= 5/6
The probability for exactly 3 of 4 randomly selected students do not prefer water can be given as,
Preq = Pmj.Pmj.Pmj.Pw
Preq = (5/6)^3 × 1/6
Preq= 125/1296
= 0.096
Thus, the required probability that exactly 3 of 4 randomly selected students do not prefer water is 0.096.

A body is floating in seawater with 2/3 of its volume above the surface. The weight of the displaced water is?
Answers
Answer:
The weight of the displaced water is the weight of the body
Step-by-step explanation:
In situations like this, the volume of the displaced water is not important.
However, it should be noted that when a body is immersed (fully or partially) in a liquid, the weight of the displaced liquid is equal to the weight of the body immersed in the liquid.
Since the weight of the body is not given, I'll conclude that the displaced water has the same weight as the body floating on the water.

Answers
Answer:

Step-by-step explanation:
Evaluate 12 - (3 y)/2 + y (2 y - 4/y) where y = 3:
12 - 3 y/2 + y (2 y - 4/y) = 12 - 3×3/2 + 3 (2×3 - 4/3)
Hint: | Express -3×3/2 as a single fraction.
-3×3/2 = (-3×3)/2:
12 + (-3×3)/2 + 3 (2×3 - 4/3)
Hint: | Multiply 2 and 3 together.
2×3 = 6:
12 - (3×3)/2 + 3 (6 - 4/3)
Hint: | Multiply -3 and 3 together.
-3×3 = -9:
12 + (-9)/2 + 3 (6 - 4/3)
Hint: | Put the fractions in 6 - 4/3 over a common denominator.
Put 6 - 4/3 over the common denominator 3. 6 - 4/3 = (3×6)/3 - 4/3:
12 - 9/2 + 3 (3×6)/3 - 4/3
Hint: | Multiply 3 and 6 together.
3×6 = 18:
12 - 9/2 + 3 (18/3 - 4/3)
Hint: | Subtract the fractions over a common denominator to a single fraction.
18/3 - 4/3 = (18 - 4)/3:
12 - 9/2 + 3 (18 - 4)/3
Hint: | Subtract 4 from 18.

Hint: | Express 3×14/3 as a single fraction.
3×14/3 = (3×14)/3:
12 - 9/2 + (3×14)/3
Hint: | Cancel common terms in the numerator and denominator of (3×14)/3.
(3×14)/3 = 3/3×14 = 14:
12 - 9/2 + 14
Hint: | Put the fractions in 12 - 9/2 + 14 over a common denominator.
Put 12 - 9/2 + 14 over the common denominator 2. 12 - 9/2 + 14 = (2×12)/2 - 9/2 + (2×14)/2:
(2×12)/2 - 9/2 + (2×14)/2
Hint: | Multiply 2 and 12 together.
2×12 = 24:
24/2 - 9/2 + (2×14)/2
Hint: | Multiply 2 and 14 together.
2×14 = 28:
24/2 - 9/2 + 28/2

Selecting a State Choose one of the 50 states at
random.
a. What is the probability that it begins with M?
b. What is the probability that it doesn't begin with a
vowel?
Answers
Answer:
PART ONE- 8/50 PART 2-38/50
Step-by-step explanation:
First of all, we know that there are 50 states. Lets see how many states begins with M first.
Maine (27 C, 5 P)
Maryland (28 C, 5 P)
Massachusetts (29 C, 4 P)
Michigan (28 C, 4 P)
Minnesota (28 C, 2 P)
Mississippi (27 C, 6 P)
Missouri (25 C, 3 P)
Montana (27 C, 6 P)
There are 8 states which means that the probabilty is 8/50 which simplifies to 4/25
We know that 12 states begins with a vowel. 50-12 is 38/50
The probability that it begins with M is 0.16 and the probability that it doesn't begin with a vowel is 0.76
What is probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur.
Given that, Selecting a State, Choose one of the 50 states at random.
We know that, P(A) = n(A)/n(S)
where, P(A) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.
a) There are 8 states which begins with M, that means the probability = 8/50 = 4/25 = 0.16
b) We know that 12 states begins with a vowel,
Therefore, the probability that it doesn't begin with a vowel = 1 - 12/50 = 38/50 = 0.76
Hence, The probability that it begins with M is 0.16 and the probability that it doesn't begin with a vowel is 0.76

The only zero of the equation 0=18c³−50c is c = 0, as it makes the equation true when substituted.
value is a zero of the equation 0 = 18c³ - 50c,
putting in the value for c
If c = 0:
0 = 18(0)³ - 50(0)
0 = 0 - 0
0 = 0 (True)
If c = 2:
0 = 18(2)³ - 50(2)
0 = 18(8) - 100
0 = 144 - 100
0 = 44 (False)
If c = -1:
0 = 18(-1)³ - 50(-1)
0 = 18(-1) + 50
0 = -18 + 50
0 = 32 (False)
only c = 0 is a zero of the equation 0 = 18c³ - 50c.
The equation 0 = 18c³ - 50c has only one zero, which is c = 0, as it satisfies the equation when substituted.
