Answer:

The numbers are 36 and 42

Step-by-step explanation:

Represent the two numbers  by m and n, m being the larger number and n the smaller.  Then

m = n + 6.  also, 7n = 6m

Substitute n + 6 for m in the second equation:  7n = 6(n + 6).

Performing the indicated multiplication, we get 7n = 6n + 36, or n = 36.

Then m = n + 6, which here is m = 36 + 6 = 42.

The numbers are 36 and 42.

An exponential function for the amount in the account after T years if the interest of 8% is compounding annually on initial amount 1700 is: P_T = 1700(1.08)^T

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

Instead of calculating the interest on the initial amount, the compound interest repeats calculating interest on (old amount + interest to be paid).

For this case, we're specified that:

Let P be the inital amount, and r be the rate of interest compounding per unit of time (in decimal)

Let [tex]P_t[/tex] be the amount after t unit of time(same unit as the interest).

Then after 1 year, the new amount would be:
[tex]P_{t+1} = P_t + 100r \%\text{ of }P_t}\\P_{t+1}= P_t + P_t \times r\\P_{t+1} = P_t(1+r)[/tex]

Thus, we get:
[tex]P_t = P_{t-1}(1+r) = P_{t-2}(1+r)(1+r) = P_{t-2}(1+r)^2\\\\P_t = P_{t-t} (1+r)^t = P_0(1+r)^t[/tex]

where P₀ is the initial amount (as amount at t = 0 is initial amount)

Thus, we get:

[tex]P_t = P(1+r)^t[/tex]

Here, putting P = 1700, r = 0.08, and t = T, we get:

[tex]P_T = 1700(1.08)^T[/tex]

Thus, an exponential function for the amount in the account after T years if the interest of 8% is compounding annually on initial amount 1700 is: [tex]P_T = 1700(1.08)^T[/tex]

Answer:

B . The graph intercept at two points, (2,0) and (6,0)

Answer: (4,-2)

Step-by-step explanation:

(4,-2)

Answer:

y = x - 2

Step-by-step explanation:

Going from M to N, the run (increase in x) is 6, from 1 to 7.  The rise (which is actually a decrease here) is -6, from 5 to -1.  Thus, the slope of the line segment MN is m = rise / run = -6/6, or -1.

The slope of the perpendicular bisector is the negative reciprocal of this m = -1, and is +1.

This bisector passes through the midpoint of segment MN.  The x-coordinate of this midpoint is (1 + 7)/2, or 4, and the y-coordinate is (5 - 1)/2, or 2:  (4, 2).

Knowing both a point on this bisector (4, 2) and the slope of the bisector (+1), we can modify the point-slope form of the equation of a straight line, y - k = m(x - h), to obtain y -2 = 1(x - 4), or y = 2 + x - 4, or y = x - 2

Hello!

This question is relating powers and simplification.

Let's look at the term in the denominator first, which is [tex]d^0[/tex].

The zero exponent rule states that anything to the 0th power, will be 1.

Meaning that we can simplify this expression to [tex]6c^{-3}[/tex].

Now let's look at the term we have left.

The negative exponent rule states that anything to the negative power can be moved to the other side of the fraction and have its exponent turn into a positive exponent.

Meaning that we can simplify [tex]6c^{-3}[/tex] to [tex]\frac{6}{c^3}[/tex].

Answer:

There are 18 balls in the bag:

6 are red

6 are yellow

6 are green.

A ball is drawn at random and then returned.

Then another ball is drawn.

Now, let's analyze each option and let's see if it is true or not.

A) The probability of drawing at random a green ball is equal to the quotient between the number of green balls and the total number of balls.

Then for the first draw, the probability is 6/18

Because the drawn ball is returned, for the second draw we still have 6 green balls and 18 balls in total, then the probability still is 6/18

Statement A is true

B) if we define the notation:

YR

as:

Yellow in the first draw, red in the second draw.

The possible outcomes are:

YR

YG

YY

RR

RG

RY

GR

GG

GY

So we have a total of 9 outcomes, we also can calculate this in the following way:

For the first event (first draw) we have 3 possible outcomes (Y, G, and R)

For the second event (second draw) we have again 3 possible outcomes.

The total number of outcomes is the product between the possible outcomes for each event, this is:

3*3 = 9

Then statement B is false.

C) The probability of drawing a red ball first is:

p = 6/18

The probability of NOT drawing a red ball second, is equal to the probability of drawing a yellow or green ball second (we have 12 balls that are green or yellow, and 18 total balls) then this probability is:

q = 12/18

The probabilities are different, then we can conclude that statement C is false.

fD) The expected probabilty of drawing a red ball and then a yellow ball is the product of the individual probabilities, this is:

prob of drawing a red ball first = 6/18

prob of drawing a yellow ball second = 6/18

Joint probability:

P = (6/18)*(6/18) = (1/3)*(1/3) = 1/9

So statement D is true.  (it says 19, i suppose that there is a mistake in this sentence and it actually should say 1/9)

21 days

Step-by-step explanation:

February has 28 days

28/4=7

1 quarter of 28 is 7

Since one quarter was above freezing, 3 were below freezing

3x7=21

21 days is the final answer

Answer:

21 days

Step-by-step explanation:

There are 28 days in February.

If one quarter of the days had a temperature above freezing, that means that three quarters of the days had a temperature below freezing.

Find how many days were below freezing by multiplying 28 by 3/4

28(3/4)

= 21

So, 21 days in February were below freezing.

Answer:

Step-by-step explanation:

4 appears the most so that's the mode.

Mean = (Sum of numbers)/(3 numbers)

Mean = (4 + 4 + 10)/3

Mean = (18)/3

Mean = 6

The three numbers that have a mode of 4 and a mean of 6​ are 4, 4, and 10.

Mean is defined as the ratio of the sum of the number of the data sets to the total number of the data. A set of data values mode is the value that appears the most frequently.

The three numbers that have a mode of 4 and a mean of 6 will be calculated below:-

Let us suppose the three numbers are 4, 4, and 10 the mean will be calculated as:-

Mean = (Sum of numbers)/(3 numbers)

Mean = (4 + 4 + 10)/3Mean = (18)/3

Mean = 6

Therefore, the three numbers that have a mode of 4 and a mean of 6​ are 4, 4, and 10.
