Step-by-step explanation:

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.

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:

Total distance walked by boys = [tex]\frac{11}{12}[/tex] miles

Step-by-step explanation:

Given that:

Distance walked from school to Bocas house = 1/4 miles

Distance walked from Paul's house to the park = 4/6 miles

Total distance walked = [tex]\frac{1}{4}+\frac{4}{6}[/tex]

Total distance walked = [tex]\frac{3+8}{12}[/tex]

Total distance walked = [tex]\frac{11}{12}[/tex] miles

Hence,

Total distance walked by boys = [tex]\frac{11}{12}[/tex] miles

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

Step-by-step explanation:

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

Answer:

Martin drove 53,558 miles.

Step-by-step explanation:

If you add up the amount of miles his son and wife drove, you get 32,898. To get the answer, you would subtract that from the total number of miles to get 53,558.

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.

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.

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%

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

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.
