The difference in temperature is currently six degrees Celsius. Therefore, the appropriate reaction is six degrees Celsius.
What is the difference in temperatures?When two independent temperature readings are subtracted, or when calculating the amount of temperature rise or fall, the result is a temperature difference, also referred to as a delta temperature (T).
Simply subtract the smaller amount from the larger one to determine the difference in temperature, in this case 19 degrees Celsius from 25 degrees Celsius. We now have a six-degree Celsius temperature difference as a result. Therefore, six degrees Celsius, is the appropriate response.
Due to the varied amounts of radiation the Earth receives from the Sun at various periods of the year, there are variations in climate all over the world. The equator receives more heat from the Sun than the north and south poles, where the angle of the Sun's beams is lower.

Find the probability P(E or F) if E and F are mutually exclusive, P(E)= 0.30, and P(F) = 0.47. The probability P(E or F) is (Simplify your answer.)
Given that P(E)= 0.30 and P(F)= 0.47, the probability of P(E or F) if E and F are mutually exclusive will be 0.77.
What is probability?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Here,
P(E)=0.30
P(F)=0.47
P(E∩F)=0 as they are mutually exclusive
P(E∪F)=P(E)+P(F)-P(E∩F)
=0.30+0.47
P(E∪F)=0.77
The probability of P(E or F) if E and F are mutually exclusive will be 0.77 given that P(E)= 0.30, and P(F) = 0.47.

The value of the piecewise function h(x) at x = 2 is (b) -1
How to evaluate the piecewise functionFrom the question, we have the following parameters that can be used in our computation:
Part 1:
h(x) = x cubed for x less than negative 3
Part 2:
h(x) = 2 times x squared minus 9 for negative 3 is less than or equal to x which is less than 4,
Part 3
h(x) = 5 times x plus 4, for x greater than or equal to 4
When the above statements are represented properly, we have the following equations
Part 1: h(x) = x³ for x < -3
Part 2: h(x) = 2x² - 9 for -3 ≤ x < 4
Part 3: h(x) = 5x + 4, for x ≥ 4
To calculate the function h(2), we use the domain -3 ≤ x < 4
So, we have the following function
h(x) = 2x² - 9
Substitute the known values in the above equation, so, we have the following representation
h(2) = 2(2)² - 9
Evaluate the expression
h(2) = -1
Hence, the value is (b) -1

Which equation represents the linear relationship between the x-values and the y- values in the table
The equation of a line that represents the table is y = 6x - 5.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
To obtain the linear equation first we need slope(m) = (y₂ - y₁)/(x₂ - x₁)
= (1 + 11)/(1 + 1) = 12/2 = 6.
Now, we'll take any one of these coordinate points and construct an equation in slope-intercept form,
- 11 = 6(-1) + b.
- 11 = - 6 + b.
b = - 5.

How to find the g[f(0)] of the function?
A function is a relationship between inputs where each input is related to exactly one output
Given: f(x)= 2x+8, g(x)= 5x-2/4 and h(x)= 2x+6/x
(a) g[f(0)]
Substitute x = 0 into f(x)= 2x+8 to get f(0)
f(0) = 2(0)+8 =8
g[f(0)] = g(8)
Substitute x = 8 into g(x)= 5x-2/4 to get g[f(0)]
g[f(0)] = g(8)
g[f(0)] = 5x-2/4
g[f(0)] = 5(8)-2/4 = 9.5
b) f(-5)
Substitute x = -5 into f(x)= 2x+8 to get f(-5)
f(x)= 2x+8
f(-5)= 2(-5)+8 = -2
c) f[h(3)]
h(x)= 2x+6/x
h(3) = 2(3)+6/3 = 4
f[h(3)] = f[4]
f[4] = 2(4)+8 = 16
f[h(3)] = 16
d) h°f(x)
h°f(x) = h(2x+8)

Deshaun wants to attend a college that will cost $25,600 for the first year. His uncle gave him a special gift of $2500 to use toward the cost. Deshaun plans to attend the college in 7 years. How much must Deshaun save each month to have enough for the first-year cost?
Deshaun must save the amount of $275 each month to have enough for the first-year cost.
As per the given question, we have
The first-year cost of college = $25,600
The gift cost = $2500
The amount left to pay will be:
⇒ first-year cost - gift cost
⇒25,600 - 2,500 = 23100
The months left till college = 7 × 12 = 84
So, he would have to save per month :
⇒ 23,100/84
Apply the division operation, and we get
⇒ 275
Thus, he must save the amount of $275 each month to have enough for the first-year cost.

a) represent the information given in equation form
b) express as a quadratic equation
c) solve the quadratic equation to find possible values of x
d) if told that the two numbers are positive numbers what are the values of the two original numbers?
The values of the two original numbers are 7 and 9.
Two numbers when multiplied equal 63 if one number is x and the other number is greater than x by 2.
As per the given phrase, the information given in equation form is as
x × (x + 2) = 63
It expresses as a quadratic equation:
x² + 2x - 63 = 0
Solve the quadratic equation to find possible values of x
x² + 9x - 7x - 63 = 0
x(x + 9) - 7(x + 9) = 0
(x + 9)(x - 7) = 0
(x + 9) = 0 and (x - 7) = 0
x = -9 and x = 7
Since we were told that the two numbers are positive numbers so take x = 7.
Thus, the values of the two original numbers are 7 and 9.

Amanda is the manager of Gladrags. She just got a new shipment of jeans and is pricing them for the store to make money. Her invoice for the jeans
states that the jeans cost her store $20 per pair. Amanda marks the jeans up to sell for $55 per pair. Find the percent of change.
O 175% increase
O 175% decrease
O 17.5% increase
O 17.5% decrease
To find the percent of change, we need to calculate the difference between the original price and the new price, and then divide this difference by the original price and multiply by 100%.
The difference between the original price of $20 and the new price of $55 is $55 - $20 = $35.
The percent of change is: ($35/$20) * 100% = 1.75 * 100% = 175%
Since the new price is higher than the original price, this is an increase. Therefore, the percent of change is a 175% increase. The correct answer is therefore
O 175% increase.
