Step-by-step explanation:

The Slope-Intercept form of an equation of a line, is:

Where "m" is the slope and "b" the y-intercept.

You know that this line passes through the point (-1,3) and its slope is 2. Then:

Substitute these values into the equation and solve for "b":

Knowing "m" and "b", you can determine that the Slope-Intercept form of the equation of this line, is:

Since the value of "y" is zero when a line intersects the x-axis, you can substiute that value into the equation in Slope-Intercept form and solve for "x", in order to find the x-intercept:

The Standard form of the equation of a the line, is:

Where "A", "B" and "C" are Integers ("A" must be positive).

The vertical displacement is of 2 units down, the correct option is B.

Remember that for a function f(x), a vertical displacement of N units is written in general form as:

g(x) = f(x) + N

If N > 0, the translation is upwards.

if N < 0, the translation is downwards.

Here we assume that we start with the parent cosine function:

y = cos(x)

And the transformed function is:

y = -2 - cos(x - π)

So we have some transformations, but the vertical translation is of 2 units down. So the correct option is B.

Answer:

C) When two fractions have equal denominators, the fraction with the greater numerator is the greater fraction.

Step-by-step explanation:

When comparing fractions, you do not use the denominator to compare. You use the numerator. Whichever fraction has the largest numerator, when the denominators are equal, is the greater fraction. When the fractions have unequal denominators, you find the least common denominator between them and then compare the numerators. Whichever one has the bigger numerator is the greater fraction.

Step-by-step explanation:

From the question we are told that

The logarithmic function \(y= 398-73 lnx\)

Price p= $275

Generally we solve mathematically for the equation \(y= 398-73 lnx\)

\(y= 398-73 lnx\)

\(275= 398-73 lnx\)

\(73 lnx=123\)

\(lnx=\frac{123}{73}\)

Therefore

\(x=e^(^\frac{123}{73}^)\)

\(x=5.4\)

Nearest whole number

\(x=5\)

The number of required hand-held electric organizers would be 5, option b. Understand the step-by-step calculations below.

The logarithm is an exponent or power to which a base must be raised to obtain a given number.

Mathematically, logarithms are expressed as, m is the logarithm of n to the base b if \(bm = n\), which can also be written as \(m = log_nb\).

Given function is,

\(y=398-73 lnx\)

Also, the cost is $275 then from the given equation,

\(398-73 lnx=275\)

Now, solving the above equation we get,

\(398-73 lnx=275\\73ln=398-275\\lnx=\frac{123}{73}\)

Now, shifting the algorithm into another side we get the exponential equation as,

\(\\x=e^{\frac{123}{73} }\\x=5.39\\x\approx5\)

The probability of selecting one of each is (4/52) × (4/51) = 1/221.

The probability of them being of different colours is (26/52) × (25/51) = The probability of selecting one of each is (13/52) × (13/51) = 1/221.

The probability of not selecting one is (39/52).

The probability of no numbered card being selected is 2/52.

The probability of no even numbered spade being selected is 11/13.

The probability of one odd numbered black card being selected is 8/52.

Probability is a measure of the likelihood of an event occurring. It is usually expressed as a number between 0 and 1, where 0 indicates that an event is impossible, and 1 indicates that an event is certain. Probability is used to describe the likelihood of outcomes or results of random events.

i)The probability of one being a king and the other a queen is 1/221. This is because there are 4 kings and 4 queens and so the probability of selecting one of each is (4/52) × (4/51) = 1/221.

ii)The probability of both cards being of different colours is 17/51. This is because there are 26 red cards and 26 black cards, and since there are only two cards being drawn, the probability of them being of different colours is (26/52) × (25/51) = 17/51.

iii)The probability of one being a card of spades and the other a card of diamonds is 1/221. This is because there are 13 spades and 13 diamonds, and so the probability of selecting one of each is (13/52) × (13/51) = 1/221.

iv)The probability of no heart card being selected is 39/52. This is because there are 13 heart cards, and so the probability of not selecting one is (39/52).

v)The probability of no numbered card being selected is 2/52. This is because there are 52 numbered cards.

vi)The probability of no even numbered spade being selected is 11/13. This is because there are 13 spades, of which 6 are even numbered, and so the probability of not selecting one is (11/13).

vii)The probability of one odd numbered black card being selected is 8/52. This is because there are 26 black cards, of which 8 are odd numbered, and so the probability of selecting one is (8/52).

The millimetres of each solution needed are 80 millimetres and 50 millimetres, respectively

From the question, we have the following parameters that can be used in our computation:

Volume needed  = 130mL

Proportion = 59%

Available proportions = 44% and 83%

Represent the type of solutions with x and y

So, we have the following system of equations:

x  + y = 130

0.44x + 0.83y = 59% * 130

So, we have

x  + y = 130

0.44x + 0.83y = 76.7

Make x the subject in x  + y = 130

x = 130 - y

Substitute x = 130 - y in 0.44x + 0.83y = 76.7

0.44(130 - y) + 0.83y = 76.7

So, we have

57.2 - 0.44y + 0.83y = 76.7

Evaluate the like terms

0.39y = 19.5

Divide both sides by 0.39

y = 50

Substitute y = 50 in x = 130 - y

x = 130 - 50

Evaluate

x = 80

Hence. the amount of each is 80 and 50 millimetres

Step-by-step explanation:

To calculate the probability of getting at least four hearts when dealing five cards from a standard deck, we can use the concept of combinations and probability.

There are a total of 52 cards in a standard deck, and 13 of them are hearts (assuming no jokers). So the probability of drawing a heart on the first card is 13/52, or 1/4.

Now, there are two possible scenarios that would result in at least four hearts:

Four hearts and one non-heart: This can happen in C(13,4) * C(39,1) ways, where C(n, k) is the number of combinations of n items taken k at a time. The first part C(13,4) represents choosing 4 hearts out of 13, and the second part C(39,1) represents choosing 1 non-heart out of the remaining 39 cards. The total number of ways to choose 5 cards from 52 is C(52,5).

Five hearts: This can happen in C(13,5) ways, where C(13,5) represents choosing all 5 hearts out of 13.

So, the total number of favorable outcomes is C(13,4) * C(39,1) + C(13,5), and the total number of possible outcomes is C(52,5). Therefore, the probability of getting at least four hearts is:

P(at least 4 hearts) = (C(13,4) * C(39,1) + C(13,5)) / C(52,5)

Plugging in the values and simplifying, we get:

P(at least 4 hearts) = (C(13,4) * C(39,1) + C(13,5)) / C(52,5)

= (715 * 39 + 1287) / 2,598,960

= 27,885 / 2,598,960

≈ 0.0107566

So, the probability of getting at least four hearts when dealing five cards from a standard deck is approximately 0.0107566 or about 1.08%.

The solution is, the percent of error, rounded to the nearest percent is 25%.

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

given that,

While viewing a herd of cattle on a ranch, Herbert estimated that there were 750 cattle in the herd.

The actual number of cattle in the herd was 600.

now, we have to find the percent of error, rounded to the nearest percent.

so, we get,

Herbert estimated that there were 750 cattle in the herd.

The actual number of cattle in the herd was 600.

so, error = 750 - 600

              = 150

so, we get,

the percent of error = 150 * 100 / 600

                                 = 25%

The tallest conifer measures 9.5 inches.

The difference is:

9.5 - 6.25 = 3.25 inches.
