The population mean annual salary for flight attendants is $56,275. A random sample of 48 flight attendants is selected from this population. Assume the population standard deviation is $1800. What is the probability that the mean annual salary of the sample is less than $56,100?

Step-by-step explanation:

Use TOA method (tan angle = opposite / adjacent)

Given Opposite = x

adjacent = 6,

[tex] \tan(37) = \frac{opposite}{adjace nt} \\ \tan(37) = \frac{x}{6} \\ x = 6 \tan(37) \\ = 4.5units(nearest \: tenth)[/tex]

Answer:

I'm going to calculate with sides 28 m

4,900 tiles used

Step-by-step explanation:

Area restaurant 28x28 = 784 m squared

each tile 40 cm = 0.4m

area of tile 0.4x0.4 =0.16

784/0.16 = 4,900

Answer:

  16

Step-by-step explanation:

There are several ways to go at this. Perhaps the simplest is to put the expression into your calculator.

__

Using the rules of exponents, you recognize ...

  a^-b = 1/a^b

  (a^b)^c = a^(bc)

  (a^b)(a^c) = a^(b+c)

__

So, we can rewrite the expression to be ...

  [tex]\displaystyle\frac{1}{2}\cdot\left(\frac{1}{2}\right)^{-5}=2^{-1}\cdot(2^{-1})^-5\\\\=2^{-1}\cdot2^{(-1)(-5)}=2^{-1}\cdot2^5\\\\=2^{-1+5}=2^4=\boxed{16}[/tex]

Answer:

350 mph

Step-by-step explanation:

The unit rate here, which is measured in miles per hour (mph) is found by dividing the distance 700 miles by the time period 2 hours:

700 miles

--------------- = 350 mph

  2 hours

Answer:

HCF = 4

LCF = 16348

HOPE THIS HELPS :)

the measure of the side = of the measure of radius because the regular hexagon have 6 sides = at each others

meaning the measure the perimeter is = 6 times the radius

and the radius = 8cm

so perimeter = 6× 8 cm

perimeter = 48cm

since the apothem is the segment perpendicular to a side thought the center and those segment are not promotional we have the notation as

r square root of 3 divided by 2

r = radius = 8 cm

by apply the formula

8square root 3 divided by 2

so the area will be

since the perimeter is 48cm

and the apothem is 8 square root of 3 divided 2

so the area will be 48 times 8 square root of 3 divided by 2 = 384 square of 3 divided by 2 .

hope that helps.

Answer:

17

Step-by-step explanation:

Given the limit of a function expressed as;

[tex]\lim_{x \to 3} x^2 + 3x - 1[/tex]

Substitute x = 3 into the function to have;

[tex]= 3^2 + 3(3) - 1\\= 9 + 9 -1 \\= 18 - 1\\= 17[/tex]

Hence the limit of the function as x tends to 3 is 17

Answer: 6 A

Step-by-step explanation:

Given

Current varies directly with Voltage

i.e.

[tex]I\ \propto V\ or\\V\ \propto\ I\\V=IR[/tex]

when V=12 V, I=4 A i.e.

[tex]\Rightarrow 12=4R\\\Rightarrow R=3\ \Omega[/tex]

When V=18 V

[tex]\Rightarrow 18=I\times 3\\\Rightarrow I=6\ A[/tex]

Current is  6 Ampere

Answer:

-3

Step-by-step explanation:

-9u+9u is 0 so all you are left with is -3

Answer:

-3

Step-by-step explanation:

-9u + 9u - 3

-9u and 9u cancel out, so it simplifies to -3

Answer:

132.

Step-by-step explanation:

If 12% are sold then 100-12 = 88% are unsold.

12% = 18 oranges

1%   =  18/12 = 1.5 oranges,

88% = 1.5 * 88 = 132.

Answer:

y + 13 = 5(x + 2)

Step-by-step explanation:

the point is (-2 , -13)

Point slope form is: y - y1 = m(x - x1)

y1= -13

x1= -2

y - -13 = 5 (x - -2)

y +13 = 5(x+2)

Answer:

[tex]\boxed {\boxed {\sf -0.92}}[/tex]

Step-by-step explanation:

A correlation coefficient is a number ranging from -1 and 1 that measures the strength and direction of a linear relationship.

Since the question only asks for the strongest relationship and does not ask for the direction (positive/negative), we can simply choose the number closest to -1/1. Therefore, the answer is -0.92.
