Complete question :

Of 50 employees of a store located in downtown Boston, 18 people take the subway to work, 12 take the bus, and 7 people take both the subway and the bus. How many employees (a) Take the subway or the bus to work? employees (b) Take only the bus to work? employees (c) Take either the bus or the subway to work (but not both)? employees (d) Get to work by some other means? employees

Answer:

23 ; 5 ; 16 ; 13

Step-by-step explanation:

Given that:

Subway (s) = 18

Bus (b) = 12

Subway and bus = 7

a) Take the subway or the bus to work?

Number of subway + number of bus - (subway and bus)

18 + 12 - 7 = 23

(b) Take only the bus to work?

Number of bus - (subway and bus)

12 - 7 = 5 employees

(c) Take either the bus or the subway to work (but not both)?

Number of bus - (subway and bus) + Number of bus - (subway and bus)

(12 - 7) + (18 - 7) = 5 + 11 = 16 employees

(d) Get to work by some other means?

Total employees - (subway + bus + subway and bus)

50 - (18 + 12 + 7)

50 - 37

= 13 employees

The dimensions of the scale copy of the rectangle are given by 8 inches and 16/3 inches respectively.

What is a rectangle?

A rectangle is a closed geometric figure with opposite sides parallel and equal to each other. In a rectangle, all the angles are equal and right to each other. The diagonals of a rectangle bisect each other.

Calculating the dimensions of the scale copy

Given length and width of a rectangle are 12 inches and 8 inches respectively

Lexi draws a scale copy of this rectangle using scale factor ⅔.

The new dimensions of the scale copy of the rectangle are given below:

Length Of the scale copy of rectangle = 12 × (⅔) = 8 inches

Width Of the scale copy of rectangle = 8 × (⅔) = 16/3 inches

Hence, the dimensions of the scale copy of the rectangle are 8 inches and 16/2 inches respectively.

Answer:

28 eggs

Step-by-step explanation:

It takes a hen and a half to lay an egg and a half in a day and a half - this means it takes 1 hen to lay 1 egg in a day and a half. Therefore, 1 hen will lay 4 eggs in 6 days, and 7 hens will lay 28 eggs in 6 days.

Answer:

18

Step-by-step explanation:

in 6 days there is 144 hours divide that by 36 (a day and a half) would be 4 so 4 days of the 6 the hens would lay an egg and a half. there is 6 hens divide that by 1.5 would be 4 times that together would be 16 but they laid an egg and a half so add .5x4 so add 2 to the 16 which gives 18

Stretched horizontally by a factor of 1/2:

Stretched vertically by a factor of 4:

Multiply the function by 4:

Stretched horizontally by a factor of 1/3:

Multiply the x-variable by 3:

Subtract 4 from the function:

Answer:

30

Step-by-step explanation:

25£ : 650 rubles

x£ : 780 rubles

25/x = 650/780

(cross multiply)

650x = 25×750

650x = 18 750

divide 18 750 by 650

which is = 30

thus x = 30

780 rubles id equals to £29.64.

The unitary method is a technique for solving a problem by first finding the values of a single unit, and then finding the necessary value by multiplying the single unit value.

According to the given question

We have

£25 = 650rubles

⇒ 1 rubles = [tex]\frac{25}{650}[/tex] = £0.038

Therefore,

780 rubles = £0.038 × 780 = £29.64

Hence, 780rubles id equals to £29.64.

Answer:

x = 104°

Step-by-step explanation:

Hello!

104° and x° are called alternate interior angles because they are in between the two parallel lines, and on the opposite sides of the transversal line.

Since they are alternate interior angles, they are congruent in measure.

Therefore: x = 104°

With alternate angles concept, the value of x from the given parallel lines is 104°.

Given that, straight line m parallel to straight line n and t is the transversal.

When a transversal connects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines. At two different locations, the transversal passes through the two lines that are coplanar.

Here, x°=104° (Interior alternate angles are equal)

Therefore, the value of x from the given parallel lines is 104°.

Sqrt32 = 4[tex]\sqrt{2}[/tex], Sqrt28 = 2[tex]\sqrt{7}[/tex], Sqrt12 = 2[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Square root of 32:

First we find the prime factors of the number by making a factor tree.

32 splits into 8 and 4.

8 splits into 4 and 2

4 splits into 2 and 2

4 splits into 2 and 2

This becomes the square root of [tex]2^{2}[/tex] x [tex]2^{2}[/tex] x 2. It will simplify to:

This question is incomplete, the complete question is;

Surgical complications: A medical researcher wants to construct a

99.5% confidence interval for the proportion of knee replacement surgeries that result in complications.

- An article in a medical journal suggested that approximately 14% of such operations result in complications. Using this estimate, what sample size is needed so that the confidence interval will have a margin of error of 0.08?

Answer: a sample of operations needed is 149

Step-by-step explanation:

Given that;

confidence interval = 99.5% = 0.995 so

margin of error E = 0.08

p = 14% = 0.14

now we obtain the critical value of z t the 99.5 confidence interval

∝ = 1 - confidence interval

∝ = 1 - 0.995

∝ = 0.005

∝/2 = 0.0025

obtaining the area of probability in the right tail

Area of probability to the right is = 1 - 0.0025 = 0.9975

from probability table; critical value of t =2.81

using the formula

n = p( 1 - p ) [ (z_∝/2)/E)² ]

so we substitute  

n = 0.14 ( 1 - 0.14 ) [ 2.81 / 0.08 )²  

n = (0.14 × 0.86 ) × 1233.7656

n = 148.5453 ≈ 149

Therefore , a sample of operations needed is 149
