Answer: Someone tell me if i'm wrong but from this I think it might be the fourth one (?)

Step-by-step explanation:

y=1

A straight line in slope (m) and intercept (c) form is:y=mx +c

In this example, y is a straight line of slope 0 and y −intercept of 1 ∴ y =0⋅

x+1

Hence, the graph of y a is straight line parallel to the x −axis through the point

The function f is defined by f(x)=5x+k, where k is a constant. Find k, if the value of f at x=2 is equal to 14.

yKpoI14uk [10]

Answer:

k = 4

Step-by-step explanation:

f(x)=5x+k

Let x =2

f(2) = 5*2 +k

f(2) = 10+k

We know f(2) = 14

14 = 10+k

Subtract 10 from each side

14-10 = 10+k-10

4 =k

2nd question! BRAINLIEST and high points :D

Vesna [10]

Answer:

Step-by-step explanation:

One side is 60 so the other side is 60

X=20

4(20)-20=60

60=(4(20)-20)

60=80-20

60=60

kinda got a bit dum

Divide x^3 -3x^2 by x-2<br> . Step 1 - Fill in the missing number:

vagabundo [1.1K]

Answer:

Step-by-step explanation:

First let us write the given polynomial as in descending powers of x with 0 coefficients for missing items

F(x) = x^3-3x^2+0x+0

We have to divide this by x-2

Leading terms in the dividend and divisor are

x^3 and x

Hence quotient I term would be x^3/x=x^2

x-2) x^3-3x^2+0x+0(x^2

x^3-2x^2

Multiply x-2 by x square and write below the term and subtract

We get

x-2) x^3-3x^2+0x+0(x^2

x^3-2x^2

---------------

-x^2+0x

Again take the leading terms and find quotient is –x

x-2) x^3-3x^2+0x+0(x^2-x

x^3-2x^2

---------------

-x^2+0x

-x^2-2x

Subtract to get 2x +0 as remainder.

x-2) x^3-3x^2+0x+0(x^2-x-2

x^3-2x^2

---------------

-x^2+0x

-x^2+2x

-------------

-2x-0

-2x+4

------------------

-4

Thus remainder is -4 and quotient is x^2-x-2

Answer:

1 - NORM.DIST(625, 600, 15 ,TRUE)

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In Excel:

We use the norm.dist command.

NORM.DIST(x, mean, standard_dev ,cumulative)

x is the tested value, mean and standard_dev are the mean and the standard deviation, while cumulative we use true to find a probability of a value lower than x, so for a value higher than x, we use:

1 - NORM.DIST(x, mean, standard_dev ,TRUE)

Mean of 600 copies and a standard deviation of 15 copies.

mean = 600, standard_dev = 15

You want to find the probability of selling more than 625 newspapers on any given day.

x = 625

What is the Excel Command

1 - NORM.DIST(625, 600, 15 ,TRUE)

Gene is playing a game with a bag of marbles. 3 of the marbles are blue, 4 are green, and 7 are yellow. See below for awarded pr

jek_recluse [69]

Answer:

Step-by-step explanation:

Gene is playing a game with a bag of marbles. If 3 of the marbles are blue, 4 are green, and 7 are yellow and awarded prices for the marbles are $2 green $0.5 yellow $4 blue, the expected payout for Gens game is expressed as shown;

If a blue marble costs $4, 3 blue marbles will cost 3*$4 = $12

If a green marble costs $2, 4 green marbles will cost 4*$2 = $8.0

If a yellow marble costs $0.5, 7 yellow marbles will cost 7*$0.5 = $3.5

Total payout for Gene's game will be the equivalent to $12+ $8 + $3.5 = $23.5.

<em>Hence Gene expected cost will be $21.5</em>
