A coffee is sitting on Mr. Hunt's desk cooling. It cools according to the function T=70(0.80)^x+20, where x is the time in minutes and T is the temperature in degree Celsius.
Answers
Answer:
90 degrees
Step-by-step explanation:
Complete question
A coffee is sitting on Mr. Hunt's desk cooling. It cools according to the function T=70(0.80)^x+20, where x is the time in minutes and T is the temperature in degree Celsius. WHAT IS THE INITIAL temperature of the coffee
The initial temperature occurs at x = 0
Substitute x = 0 into the expression;
T=70(0.80)^x+20
T =70(0.80)^0+20
Since any value raise to power of zero is 1, hence;
T = 70(1)+20
T = 70+20
T = 90 degree Celsius
Hence the initial temperature of the coffee is 90 degrees
The initial temperature of the coffee is 90 degrees.
The function is represented as:
[tex]\mathbf{T = 70(0.80)^x + 20}[/tex]
At the initial temperature, x = 0.
So, we have:
[tex]\mathbf{T = 70(0.80)^0 + 20}[/tex]
Expand
[tex]\mathbf{T = 70 \times 1 + 20}[/tex]
Multiply
[tex]\mathbf{T = 70 + 20}[/tex]
Add
[tex]\mathbf{T = 90}[/tex]
Hence, the initial temperature of the coffee is 90 degrees.

Answer: 2 independent sample test of proportions
Step-by-step explanation:
The teo independent sample test of proportion is also referred to as the two proportion z-test and it simply allows the researcher to compare the two proportions in order to ascertain if they're the same or not.
In this case, the null hypothesis will be that that the proportions given in the research are the same while the alternate hypothesis will be that there is a difference between the proportions given.
The kind of analysis that would be most adequate for the given study:
Test of 2 Independent Proportions.
Independent Proportions
The test of two independent proportions is characterized as the method of study in which samples are opted randomly and allowed to remain independent.
In such a study, a minimum of 5 failures and successes are considered to reach a conclusion.

slope = -2/5; y-intercept = 0
Answers
Answer:
Y= -2/5X
Step-by-step explanation:
the equation is y=mx + b
slope: -2/5x
y- intercept: 0
all you do is combined your slope and y-intercept together: Y= -2/5X , you dont need to add +0 because it gonna just still be the same as y= - 2/5x
Y= -2/5X or y= -2/5x + 0 is the same so it can be any of these 2 that you pick but the correct way is y= -2/5x

Three square flower beds with side of 2m are dug in a rectangular piece of land whose length is 5.2 m and width is 4.8 m. What is the area of the remaining land?
Answers
Answer: 12.96 m²
Step-by-step explanation:
The area of the piece of land that the flower beds were dug in is:
= Length * width
= 5.2 * 4.8
= 24.96 m²
The flower beds were 3 in number and all had the shape of a square.
Their area is:
= 3 * (Length * width)
= 3 * ( 2 * 2)
= 3 * 4
= 12 m² for all three flower beds
Remaining land:
= 24.96 - 12
= 12.96 m²

Consider the original parallelogram and the reduction.
What is the length of side A in the new parallelogram?
Answers
Given:
The given figure represents the original parallelogram and the reduction.
To find:
The length of side A in the new parallelogram.
Solution:
We know that the original figure is always similar to its reduction. So, both parallelograms are similar to each other.
The corresponding sides of similar figures are proportional.
[tex]\dfrac{45}{18}=\dfrac{5}{A}[/tex]
[tex]45\times A=5\times 18[/tex]
[tex]45A=90[/tex]
Divide both sides by 45.
[tex]A=\dfrac{90}{45}[/tex]
[tex]A=2[/tex]
The length of side A in the new parallelogram is 2 cm. Therefore, the correct option is A.
60% of the vehicles owned by a transport company are trucks, 15% are vans and the rest are buses. If there are 10 buses, how many trucks are there?
Answers
Answer:
Hope this help, pls mark me as Brainliest!
Step-by-step explanation:
60% = 0.6
15% = 0.15
10 = 0.15
Answer:
24
Step-by-step explanation:
Let x represent total number of vehicles
Let T represent number of trucks
Let V represent number of vans
Let B represent number of buses
Convert percent's to decimals:
60% = 0.6
15% = 0.15
Set up equations:
T = 0.6x
V= 0.15x
B= (1 - 0.6 - 0.15)x
For buses, the remaining portion of the 100% of vehicles is 100% -60% -15%
Since we know there are 10 buses, set B=10
B= (1 - 0.6 - 0.15)x
10= (1 - 0.6 - 0.15)x
10= 0.25 x
Divide both sides by 0.25 so that we get:
10/0.25 = x
x= 40
We now know there are 40 vehicles present. To find the number of trucks, we take 60% of the total number of vehicles
T = 0.6x
T= 0.6 (40)
T= 24
Therefore there are 24 trucks.
