You are researching the average emails received per day. You want to know how many employees you should survey if you want to know, at a 90% confidence level, that the sample mean emails per day is within 47 emails of the true mean emails per day. From above, we know that the population standard deviation is 155, and z-value is 1.645$_

Answer:

2,0

Step-by-step explanation:

6x-5y=12

subtract 6x from both sides.

-5y=-6x+12

divide -5 on both sides.

y=6/5x-12/5

Answer:

x = 2  ⇒  point (2, 0)

Step-by-step explanation:

The x-intercept is the place where the line crosses the x-axis. This is also when y = 0.

So, set y equal to 0 and solve for x:

6x - 5y = 12

6x - 5 * 0 = 12

6x = 12

x = 12/6 = 2

The x-intercept, thus, is at x = 2.

8 feet

Step-by-step explanation:

It is given that, a 3 ft tree casts a 10 ft. shadow.  It means that 1 ft long shadow will cast by [tex]\dfrac{3}{10}[/tex] feet long tree.

Let 26 ft tall tree will cast x feet long shadow. To find it using unitary method we get :

[tex]x=\dfrac{3}{10}\times 26\\\\x=7.8\ \text{feet}[/tex]

or

x = 8 feet

So, 8 feet long is the shadow of a 26 feet tall tree.

[tex]\frac{5}{20} = \frac{1}{4} = \frac{4}{16}[/tex]

Step-by-step explanation:

Given

[tex]Fraction = \frac{5}{20}[/tex]

Required

Get equivalent fractions

[tex]Fraction = \frac{5}{20}[/tex]

Divide numerator and denominator by 5

[tex]Fraction = \frac{5/5}{20/5}[/tex]

[tex]Fraction = \frac{1}{4}[/tex]

Multiply the numerator ad denominator by 4

[tex]Fraction = \frac{1 * 4}{4 * 4}[/tex]

[tex]Fraction = \frac{4}{16}[/tex]

Hence:

[tex]\frac{5}{20} = \frac{1}{4} = \frac{4}{16}[/tex]

Answer:

2267 km

Step-by-step explanation:

1890 km/3.5 hours = 2267 km/4.2 hours

2268 km far will the plane fly in 4.2 hours if it maintains the same air speed.

How far will the plane fly in 4.2 hours if it maintains the same air speed?

The formula speed = distance ÷ time can be rearranged like any other equation. The formula can be rearranged in three ways: speed = distance ÷ time. distance = speed × time.

Given,a plane flies 1890 km in 3.5 hours.

So, distance = 1890 km and time = 3.5 hours.

We know,

Distance = Speed × Time

For example, If speed of a car is 20 m/s and the car travel 60 s then the car cover total distance

[tex]= 20 \times 60 = 1200 \: m[/tex]

Again

[tex]speed = \frac{distance}{time}[/tex]

According to question,

Speed

[tex] = \frac{distance}{time} \\ = \frac{1890}{3.5} \\ = 540 [/tex]

So, speed of the plane is 540 km/hour.

Again given time is 4.2 hours

So, Distance = Speed × Time

[tex] = 540 \times 4.2 \\ = 2268 \: km[/tex]

Answer:

Step-by-step explanation:

Company A = 18 eagles for $49.32

Price per eagle = $49.32 / 18

= $2.74

Company B = 16 eagles for $43.36

Price per eagle = $43.36 / 16 eagles

= $2.71

Company C = $41.55 for 15 eagles

Price per eagle = $41.55 / 15 eagles

= $2.77

The company which has the best buy is company C, they sell 1 eagle for $2.77 (highest selling price among the three companies)

Answer:

Width of the rectangular prism

It is given to us that the volume of the rectangular prism is calculated by the given formula :-

v = lwh

Where,

v = volume

l = length

w = width

h = height

Now,

In the question we are given :-

v = 138.24 cubic inches

h =  9.6 inches

l = 3.2 inches

w = ?

Substitute these values in the volume formula given :-

138.24 = 3.2 * w * 9.6

138.24 = 30.72 * w

w = 138.24/30.72

w = 4.5

⇒ The width of the rectangular prism is 4.5 inches.

The required width of the rectangular prism is 4.5 inches.

Given information:

The volume of the rectangular prism is defined as,

[tex]V=lwh[/tex]

where l is the length, w is the width, and h is the height of the prism.

The volume of the prism is 138.24 cubic inches.

The height of the prism is 9.6 inches, and the length of the prism is 3.2 inches.

So, the width of the prism can be calculated as,

[tex]V=lwh\\138.24 =3.2\times w\times 9.6\\138.24 =30.72\times w\\w=\dfrac{138.24}{30.72}\\w=4.5\rm \; inch[/tex]

Therefore, the required width of the rectangular prism is 4.5 inches.
