A company needs to hire 4 new employees. There were 55 male and 40 female applicants. Find the probability that all 4 people hired are male.
Answers
ANSWER
0.11
EXPLANATION
There are 95 (that is 55 + 40) choices in total and 55 favourable choices.
Now,
The probability of the 1st person being a male is 55/95
The probability of the 2nd person being a male is 54/94
The probability of the 3rd person being a male is 53/93
The probability of the 4th person being a male is 52/92
Hence, the probability of all 4 being males = (55/95)x(54/94)x(53/93)x(52/92) = 0.107
Hence, the probability that all 4 people hired are male is 0.11

If x and y are two positive real numbers such that x 2 +4y 2 =17 and xy =2, then find the value of x- 2y. a. 3 b. 4 c. 8 d. 9
Answers
Answer: The value of x- 2y is a. \(\pm 3\).
Step-by-step explanation:
Given: x and y are two positive real numbers such that \(x^2+4y^2=17\) and \(xy= 2\) .
Consider \((x-2y)^2=x^2-2(x)(2y)+(2y)^2\ \ \ [(a+b)^2=(a^2-2ab+b^2)]\)
\(=x^2-4xy+4y^2\)
\(=x^2+4y^2-4(xy)\)
Put \(x^2+4y^2=17\) and \(xy= 2\) , we get
\((x-2y)^2=17-4(2)=17-8=9\)
\(\Rightarrow\ (x-2y)^2=9\)
Taking square root on both sides , we get'
\(x-2y= \pm3\)
Hence, the value of x- 2y is a. \(\pm 3\).

Answer:
Sugar | Flour
¼ | 1
½ | 2
⅝ | 2½
4 | 16
Step-by-step explanation:
¼ part of sugar = 1 part flour (given)
Ratio of sugar to flour = ¼ : 1
Use this proportion to complete the table.
✔️Sugar to flour = ¼ : 1
½ : x = ¼ : 1
½/x = ¼/1
cross multiply
x*¼ = 1*½
x/4 = ½
Multiply both sides by 4
x = ½*4
x = 2
✔️Sugar to flour = ¼ : 1
x : 2½ = ¼ : 1
x : ⁵/2 = ¼ : 1
x/⁵/2 = ¼/1
Cross multiply
x*1 = ¼*⁵/2
x = ⅝
✔️Sugar to flour = ¼ : 1
4 : x = ¼ : 1
⁴/x = ¼/1
Cross multiply
x*¼ = 1*4
x/4 = 4
Multiply both sides by 4
x = 4*4
x = 16

There are 12million children in the UK. If it took Santa 3 seconds to visit each child when delivering presents, how many hours would
Answers
The number of hours it will take Santa to visit the whole children is = 10,000hours
The total number of children in UK is = 12million
That is = 12,000,000.
It took Santa 3 seconds to visit each child. That is,
1 child = 3 seconds
Therefore 12,000,000 children = x seconds
x = 12,000,000 × 3 seconds
x = 36,000,000 seconds.
But 3,600 seconds = 1 hour
36,000,000 seconds = x
x = 36,000,000/3,600
x = 10,000 hours.
Therefore, the number of hours it will take Santa to visit the whole children is = 10,000 hours.

B) |x - 2| = -5
C) -|x| - 2 = 5
D) -|x - 2| = -5
Answers
Answer:
D
Step-by-step explanation:
A is impossible.
the absolute value of something is always a positive number. the negative sign before it makes it an always negative number. so, this can never be equal to +5.
B is impossible for the same reasons.
the absolute value is always positive and can never be equal to -5.
C is impossible again for the same reasons.
the negative absolute value of x is always negative. subtracting 2 from that makes the result even more negative. this can never be equal to +5.
D is the only fitting option.
we have two extreme points x = -3 and x = 7.
putting them into the equation gives us for x = -3
-|-3 - 2| = -|-5| = -5 => correct
and for x = 7
-|7 - 2| = -|5| = -5 => correct
The correct answer is -|x - 2| = -5
Each month, Braxton uses an average of 8 ounces of lotion. Calculate Braxton's total monthly savings if he purchases the brand that has the lowest price per ounce versus the highest price per ounce.

a $0.18
b $0.75
с $1.30
d $1.50
Answers
Option a: Broxton have a monthly savings of $0.18 if he purchases the brand that has the lowest price per ounce versus the highest price
Given,
Braxton’s average monthly usage of lotion = 8 ounces
The amount of two different brands of lotion are given:
Brand A: 24 ounces for $3.30
Brand B: 40 ounces for $4.60
We have to find the monthly savings of Braxton if he purchases the brand that has the lowest price per ounce versus the highest price:
We have to calculate amount for one ounce for the two brands given:
Brand A:
24 ounces for $3.30
Amount for one ounce = 3.30/24
Amount for one ounce = $0.1375
Brand B:
40 ounces for $4.60
Amount for one ounce = 4.60/40
Amount for one ounce = $0.115
Now, we have to calculate the amount for 8 ounces.
Brand A:
8 x 0.1375 = 1.1
$1.1 for 8 ounces of Brand A lotion.
Brand B:
8 x 0.115 = 0.92
$0.92 for 8 ounces of Brand B lotion.
Now, we have to calculate the savings:
Brand A – Brand B
1.1 – 0.92 = 0.18
That is, Broxton have a monthly savings of $0.18 if he purchases the brand that has the lowest price per ounce versus the highest price.

The given sequence is an arithmetic sequence and the common difference is 4.
Given, the sequence is :
3,12,48
we need to determine the common difference.
common ratio = a₂/a₁
a₂/a₁ = 12/3
a₂/a₁ = 4
a₃/a₂ = 48/12
a₃/a₂ = 4
hence the common difference is 4.
Therefore, the common difference indicates arithmetic sequence.

In Monopoly one rolls a pair of dice. Find the probability of getting a sum of 12. Round your answer to 3 digits after the decimal point.
Answers
Answer:
the probability of rolling a sum of 12 on a pair of dice in Monopoly is approximately 0.028.
Step-by-step explanation:
There are 6 possible outcomes on each die, so there are 6 x 6 = 36 possible outcomes when rolling a pair of dice. To find the probability of getting a sum of 12, we need to count the number of outcomes that add up to 12 and divide by the total number of outcomes.
The only way to get a sum of 12 is to roll a 6 on both dice. There is only 1 way to do this, so the number of outcomes that add up to 12 is 1.
Therefore, the probability of getting a sum of 12 is:
1/36 ≈ 0.028 (rounded to 3 decimal places)
So the probability of rolling a sum of 12 on a pair of dice in Monopoly is approximately 0.028.

at a large university, 68% of the students have a laptop, while only 43% of professors have one. let p hat subscript s and p hat subscript p be the sample proportions of students and professors, respectively, who have a laptop. suppose 56 students and 31 professors from this university are selected at random and asked if they have a laptop. which of the following is the correct calculation and interpretation of the standard deviation of the sampling distribution of p hat subscript s baseline minus p hat subscript p ?
Answers
The correct calculation of the standard deviation of the sampling distribution of p_hat subscript s - p_hat subscript p is 0.0934.
What do you mean by standard deviation?
In statistics, Standard deviation is a measure of the variation of a set of values.
σ = standard deviation of population
N = number of observation of population
X = mean
μ = population mean
We are given that;
Percentage of students with laptop=68%
Percentage of professors with laptop=43%
p_s = 0.68 and p_p = 0.43.
Now,
The formula for the standard deviation of the sampling distribution of the difference between two sample proportions is:
sqrt[(p_s * (1 - p_s) / n_s) + (p_p * (1 - p_p) / n_p)]
where p_s and p_p are the population proportions of students and professors who have a laptop, respectively, n_s and n_p are the sample sizes of students and professors, respectively.
We are also given that 56 students and 31 professors were selected at random and asked if they have a laptop. Therefore, n_s = 56 and n_p = 31.
Substituting these values into the formula, we get:
sqrt[(0.68 * (1 - 0.68) / 56) + (0.43 * (1 - 0.43) / 31)]
sqrt[0.00367143 + 0.00505484]
= sqrt(0.00872627)
= 0.0934 (rounded to four decimal places)
Therefore, by standard deviation the answer will be 0.0934.
