What is f(x)=14−0.5x? solve for f(30)

1 answer:

3 0

The function f(x) is a function of the variable x.

To solve the function for x = 30, just plug in 30 for x.

14 - 0.5(30) = -1

f(30) = -1

X2 - 4x + 3 = 0<br> lesser x =<br> greater x =<br> o

Levart [38]

Answer:

lesser x is 1

greater x is 3

Step-by-step explanation:

Here, we want to solve the equation so as to get the bigger and the lesser x values

We proceed as follows;

x^2 -4x + 3 = 0

x^2 - x-3x + 3 = 0

x(x-1) -3(x-1) = 0

(x-3)(x-1) = 0

x = 3

or x = 1

Greater x is 3

lesser x is 1

7. (05.02 MC)

Diano4ka-milaya [45]

Considering the Central Limit Theorem, we have that:

a) The probability cannot be calculated, as the underlying distribution is not normal and the sample size is less than 30.

b) The probability can be calculated, as the sample size is greater than 30.

<h3>What does the Central Limit Theorem state?</h3>

It states that the sampling distribution of sample means of size n is approximately normal has standard deviation $s = \frac{\sigma}{\sqrt{n}}$ , as long as the underlying distribution is normal or the sample size is greater than 30.

In this problem, the underlying distribution is skewed right, that is, not normal, hence:

For item a, the probability cannot be calculated, as the underlying distribution is not normal and the sample size is less than 30.

For item b, the probability can be calculated, as the sample size is greater than 30.

In an experiment, a variable, position-dependent force F(x) is exerted on a block of mass 1.0kg that is moving on a horizontal s

telo118 [61]

Answer: correct option is C

The function F(x) for 0 < x < 5, the block's initial velocity, and the value of Ff.

Step-by-step explanation:

The total work done = P.E + K.E

K.E = 1/2mv^2

The speed V depends on the position:

0 < x < 5

Also, since work done = F × distance x

The workdone also depends on F(x)

The net force = 0 that is

F + fr = 0

Where fr = frictional force.

Therefore the best option for the hypothesis of work done will be;

The function F(x) for 0 < x < 5, the block's initial velocity, and the value of Ff.

If the mean of this data is 95, find the missing data 103,99,90,86,105,96 what is the missing data

d1i1m1o1n [39]

Let, the missing number = x
Then, 103 + 99 + 90 + 86 + 105 + 96 + x / 7 = 95
579+x = 665
x = 665 - 579
x = 86

In short, Your Answer would be 86

Hope this helps!

Urgent please help..

crimeas [40]

Answer:

5.4

Step-by-step explanation:

First find the area of the square.

L times W

5 times 5=25

Now find the area of the cricle

A= $\pi$ $r^{2}$

Substitute pi with 3.14 and radius with 2.5

A= 3.14 times $2.5^{2}$

A=3.14 times 6.25

A=19.625

Now substract the area of the square from the area of the circle

Your answer will be 5.375

The rounded answer will be 5.4
