STOP RIGHT THERE. Please help me.
Answer:
the answer is B
Step-by-step explanation:
Well we can get rid of A and D because we're not adding money, we're subtracting (thats what a sale is)
So we're left with B and C.
To find what 17% of 3 is, we multiply 3 x 0.17, which totals to 0.51. It can't be C because you find 51% of 3 which is not what we're looking for, so it is B.

-4 x f (8) + 3 x g(-7) HELP ASAP
Answer:
-32
Step-by-step explanation:
-4 + f(8) + 3 x g(-7) = ?
To find f(8), look at each of the f(x) function and find x = 8. The y value is the answer you will plug in for f(8). The same goes for g(-7), but you will be looking at the g(x) function at x = -7.
f(8) = -4
g(-7) = -8
Make sure you solve in the correct order using PEMDAS.
-4 + (-4) + 3 x (-8) = -32

A.
17%
B.
21%
C.
49%
D.
51%
Answer: The correct answer is B) 21%
Step-by-step explanation:
This is a binomial model probability problem. We need to find the probability of 6 out of 10 new births at a hospital being boys. The information we need is the number of trials observed, the number of successes and the percentage chance you have of any birth being a boy. The number of trials are 10, with the number of successes being 6 (the number of trials we want to be boys) It states that 51% or 0.51 of all births in the US are boys so we can use this value to determine our answer using our binomial model formula. After simplifying we get our answer of 21% I hope this has been of use to you :)
Have a wonderful rest of your day!
The probability that 6 out of 10 births at a local hospital are boys is 21%, so option B is correct.
What is probability?The ratio of good outcomes to all possible outcomes of an event is known as probability. A lot of successful results for an experimental with 'n' results can be represented by the symbol x.
Given data:
In the U.S., 51% of all births are boys, and 49% are girls
Calculate the probability by the formula given below,
[tex]P(x) = [n! / {x!(n-x)!}]P^xQ^{n-x}[/tex]
Here x = 6 and n = 10, put the values,
P(x) = [10! / {6!(10-6)!}] × 51⁶ × 49⁽¹⁰⁻⁶⁾
P(x) = [10! / {6!4!}] × 0.51⁶ × 0.49⁴
P(x) = 210 × 0.0176 × 0.0577
P(x) = 0.21
P(x) = 21 %
Therefore, the probability that 6 out of 10 births at a local hospital are boys is 21%.

Answer:
B. 112°
Step-by-step explanation:
4x -4 = (3x+4) + (2x-44)
4x -4 = 5x - 40
5x - 4x = -4 + 40
x = 36
∠BCA = 3 * 36 + 4 = 112
Find the unknown angle measure by solving for the given variable.
Supplementary angles
Step-by-step explanation:
Given that,
∠PSQ = 13x+7
∠QSR = 42x+8
We need to find the measure of angles.
We can use the property of linear pair. ATQ,
13x+7 + 42x+8 = 180 (Linear pair)
Taking like terms,
13x+42x = 180 - 7-8
55x = 165
x = 3
So,
∠PSQ = 13x+7 = 13(3) + 7 = 46°
∠QSR = 42x+8 = 42(3) + 8 = 134°
Hence, this is the required solution.

URGENT if triangle FGH is congruent to triangle KJH, find FH
Answer:
FH =KH if triangle FJH and KJH is congruent
Step-by-step explanation:
If two triangles FJH and KJH as shown n figure is congruent if,
FJ = KJ,
FH =KH and
JH =JH common
Triangle is congruent by SSS theorem
Therefore FH =KH
Answer:
FH=39
Step-by-step explanation:
FGH~KJH
GH=x+8
FH=4x-25
JH=32
KH=52
(these are the measurements I have)
x+8 / 32 = 4x-25 / 52
(cross multiply)
52(x+8) = 32(4x-25)
52x+416 = 128x-800
(subtract the 52x from the 128x)
416 = 76x-800
(add the 800 to the 416)
1216 = 76x
(divide the 76 over the 1216)
x = 16
(now plug x into FH)
FH = 4x-25
FH = 4(16)-25
FH = 39

A patient needs a total dose of 50 grams of albumin. The pharmacy has 50 m
bottles of 25% Albumin in stock. How many bottles should the pharmacy
technician prepare to provide the required dose?
Answer:
4,000 bottles.
Step-by-step explanation:
Given that the patient needs a total dose of 50 grams of albumin, and the pharmacy has bottles of 50 milligrams with 25% albumin, to determine how many bottles the patient should purchase the following calculation must be performed:
1 g = 1000 mg
50 g = 50,000 mg
50 x 0.25 = 12.5
50,000 / 12.5 = X
4,000 = X
Therefore, the patient must purchase 4,000 bottles to obtain the required dosage.
The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min. If one such class is randomly selected, find the probability that the class length is between 50.8 and 51 min.
Answer: the probability that the class length is between 50.8 and 51 min is 0.1 ≈ 10%
Step-by-step explanation:
Given data;
lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min
hence, height = 1 / ( 52.0 - 50.0) = 1 / 2
now the probability that the class length is between 50.8 and 51 min = ?
P( 50.8 < X < 51 ) = base × height
= ( 51 - 50.8) × 1/2
= 0.2 × 0.5
= 0.1 ≈ 10%
therefore the probability that the class length is between 50.8 and 51 min is 0.1 ≈ 10%
