Answer:

f(1) = 9

Step-by-step explanation:

Evaluate f(x) = 4x+5 by replacing both instances of x with '1' as follows:

f(1) = 4(1) + 5 = 9

Thus, f(1) = 9

For employees at a large company, the mean number of overtime hours worked each week is 9.2 hours with a population standard dev

topjm [15]

Answer:

$z=\frac{9.3-9.2}{\frac{1.6}{\sqrt{49}}}= 0.4375$

And we can use the normal table and the complement rule we got:

$P(z>0.4375)= 1-P(z$

Step-by-step explanation:

For this case we have the following parameters given:

$\mu = 9.2 , \sigma =1.6$

We select a ample size of n=49. And we want to find this probability:

$P(\bar X> 9.3)$

And for this case is a right tail probability and we can use the z score formula given by:

$z=\frac{\bar X -\mu}{\frac{\sigma}{\sqrt{n}}}$

And replacing we got:

$z=\frac{9.3-9.2}{\frac{1.6}{\sqrt{49}}}= 0.4375$

And we can use the normal table and the complement rule we got:

$P(z>0.4375)= 1-P(z$

GUYS QUICK! what is the surface area of a sphere that has a radius of 5 cm

alisha [4.7K]

Answer:

100 pi cm^2

or approximately 314 cm^2

Step-by-step explanation:

The surface area of a sphere is given by

SA = 4 pi r^2

The radius is 5

SA = 4 *pi * 5^2

SA = 4*pi(25

SA = 100 pi cm^2

If pi is 3.14

SA = 100 *3.14 = 314 cm^2

Melanies superhero costume for the school play requires 1 5/6 yards of green fabric and 1/3 yard of yellow fabric.How many total

Katen [24]

Answer:

$2\frac{1}{6}$ yards of fabric.

Step-by-step explanation:

It is required $1\frac{5}{6}$ yards of green fabric and $\frac{1}{3}$ yards of yellow fabric to make the costume for the school play.

We are asked to calculate the total yards of fabric required.

So, the total yards of fabric needed will be the sum of green fabric length and yellow fabric length.

So, the total yards of fabric are needed for costume will be $(1\frac{5}{6} + \frac{1}{3}) = (\frac{11}{6} + \frac{1}{3}) = \frac{13}{6} = 2\frac{1}{6}$ yards. (Answer)

X(4x + 1). Need helpppp

elixir [45]

Answer:

4 $x^{2}$ +x

Step-by-step explanation:

That is the correct answer if you want to multiply x by 4x+1

x(4x+1)

(x · 4x) + (x·1) By using the distributrive property

(4 $x^{2}$ ) + (x)

= 4 $x^{2}$ + x

I hope this helps :)

Good luck!
