A line's slope or gradient, which is expressed as a number, indicates the line's steepness and X and Y directions.

The slope of the line y = 7x + 19 (5) exists 7.

The units of the slope (dy/dx), which correspond to speed or velocity, in this case are km/m.y since the y axis is measured in kilometres and the x axis in millions of years. Both the slope and the y intercept might have a positive or negative value. Slope is defined as the y-axis divided by the x-axis.

The slope expresses how quickly the dependent variable changes when the independent variable changes. The Greek capital letter D or D is frequently used by mathematicians and economics to represent change. Slope contrasts the change in the vertical axis, y, with the change in the horizontal axis, x.

Given Correct Statement is :- The data distribution is skewed to the right, which means that the right tail of the distribution is longer than the left tail. c. The data distribution is skewed to the right.

It is not possible for a data distribution to be both symmetric and skewed at the same time, as these are mutually exclusive characteristics.

A symmetric distribution is one in which the data is evenly distributed around the mean, with the left and right sides of the distribution being mirror images of each other.

A skewed distribution is one in which the data is not evenly distributed around the mean, with one tail of the distribution being longer than the other.

Based on the given options, only one statement can be true.

Option (c) states that the data distribution is skewed to the right, which means that the right tail of the distribution is longer than the left tail. Therefore, the correct statement is:

c. The data distribution is skewed to the right.

Answer:

Options (1) and (5)

Step-by-step explanation:

Given function 'f' representing the relation between temperature of the oven after 't' minutes is,

f(t) = 0.25t² + 65

Option (1).

f(0) means that when the cake was placed in the oven, its temperature was 65°.

True.

f(0) = 0 + 65 = 65

Option (2).

To find the temperature after 15 minutes, we need to find 't' when f(t) = 15

False.

We have to find the value of f(15) to find the temperature of the oven after 15 minutes.

Option (3).

Temperature of the cake was 81° F when it was kept in the oven for 8 minutes.

Given statement is False.

It should be represented by,

f(8) = 81

Option (4).

After 10 minutes,the temperature of the cake was 71.25 degree F.

False.

By putting t = 10 in the function,

f(10) = 0.25(10)² + 65

       = 25 + 65

       = 90° F

Option (5).

The temperature of the cake when the baker takes it out of the oven, can be represented by,

f(30) = 290

True.

f(30) = 0.25(30)² + 65

       = 225 + 65

       = 290

Answer:

2/3

Step-by-step explanation:

Convert the mixed fraction into an improper one:

4 2/3 = 4*3 + 2 / 3 = 14 / 3.

Then divide:

14/3 ÷ 7 = 14÷7 / 3 = 2 / 3

Answer:

14/21

Step-by-step explanation:

First, we turn 4 2/3 into an improper fraction. We do this by multiplying 4 by 3 and then adding 2 to this product.

4×3 = 12

12 + 2 = 14

Now, our equation is simplified to 14/3 ÷ 7. Now, all we can do is divide 14/3 by 7.

14/3 ÷ 7 = 14/21

So, our evaluated and simplified answer is 14/21.

[tex]No\: Solution[/tex]

x is infinity which means it has no solutions.

Given,

4 = ax - 14

We need to solve for x.

We have,

4 = ax - 14

Now,

We have to assume a = 0.

we get,

4 + 14 = ax

ax = 4 + 14

x = (4+14) / a

x = 18 / a

So,

Putting a = 0 in x = 18 / a

We get,

x = 18/0 = ∞

We can say that x has no solutions.

Thus x is infinity which means it has no solutions.

[tex]\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}=\displaystyle \frac{n}{2m^2}[/tex]

Step-by-step explanation:

Simplificación de expresiones algebraicas

Tenemos la expresión:

[tex]\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}[/tex]

La división de fracciones suele manejarse mejor utilizando la multiplicación del inverso del denominador. Es decir, para dividir la fracción a/b entre la fracción c/d se multiplica a/b*d/c para resultar (a*d)/(b*c).

Apliquemos lo anterior al problema en consideración:

[tex]\displaystyle \frac{3m^2n^2}{5(m+n)}\div \frac{12m^4n}{10(m+n)}=\displaystyle \frac{3m^2n^2}{5(m+n)}\cdot \frac{10(m+n)}{12m^4n}[/tex]

Multiplicamos los coeficientes en el numerador y denominador y eliminamos el factor (m+n):

[tex]=\displaystyle \frac{30m^2n^2}{60m^4n}[/tex]

La potencia 2 de la m se simplifica con la potencia 4 y la potencia 2 de la n se simplifica con la potencia 1. Igualmente se simplifica la fracción numérica dividiendo entre 30:

r = 14

s = 8

3/7 x 14 + 5/8 x 8

3/7 x 14 = 6

5/8 x 8 = 5

6 + 5 = 11

ok so it's like the 3/7 and 5/8 are fractions so you just multiply each one by the number their next you which in this case is r and s so it's like you're just multiplying a fraction and a number. does that make since?

Answer:

50 seconds

Step-by-step explanation:

We are told in the question that the distance between them = 100ft

Tom is able to paddle at a speed of 4 feet per second. Joe is able to paddle at a speed of 6 feet per second.

The formula for Distance = Speed × Time.

Hence, the Algebraic equation is given as:

6ft/s × t = 4ft/s × t + 100

6t = 4t + 100

6t - 4t = 100

2t = 100

t = 100/2

t = 50 seconds

Step-by-step explanation:

The probability of certainty is 100%=1

If Probability(p)=0.34

then

Probability (p) +cProbability (!p) = 1 where !p is used to denote "not "p

0.34+Probability(!p)=1

Probability(!p)=1−0.34=0.66

The probability that the event will not happen is 0.66.

The probability of an event can be defined as the chance of happening that particular event.

The probability that the event will happen is P(E) = 0.34.

Therefore, the probability that the event will not happen is

= 1 - P(E)

Answer:

The Answer is 53

Step-by-step explanation:

if angle PQR is 75 and PQS is 22... 75-22 is 53

The measure of the angles SQR if PQR measures 75° is 53 degrees

An angle is formed by joining two rays (half-lines) that have a shared terminal. The latter is referred to as the angle's vertex, while the rays are referred to as the angle's sides, legs, and arms.

We have,

<PQR = 75 degrees

<PQS = 22 degrees

From the given diagram

<PQR = <PQS + <SQR

Substitute the given values into the formula

75 = 22 + <SQR

<SQR = 75 - 22

<SQR = 53 degrees

Hence, the measure of the angles SQR is 53 degrees
