Answer:
independent variable = Time
Dependent variable = texting speed
Step-by-step explanation:
The Independent and dependent variables are used in regression analysis for making prediction. The Independent variable also called the predictor are the variables or data collected in other to influence or determine the outpjt obtained which is the dependent or predicted variable. Hence, the aim or prediction we wish to obtain, measure or determine is the dependent variable In the scenario above, the aim of the data collected is to determine the typing skill, here, the dependent variable is the typing skill. The data required to define the bthis is the data collected on typing speed which measures time taken to type.
Therefore, independent variable = Time
Dependent variable = texting speed
A tree grew 92 4/5 feet in 19 1/3 years. What was the average yearly growth rate of the tree
Answer:
4 247/290 or 4.85 ft/year
Step-by-step explanation:
93 4/5 ÷ 19 1/3 = 469/5 ÷ 58/3 = 469/5 x 3/58 = 1407/290 = 4 247/290
If a angle on the circumference of a circle is subtended by a diameter of the circle what is the angle
Answer:
The angle is 90 degrees
Step-by-step explanation:
Required
Angle subtended by the diameter
The theorem to solve this is:
The angle subtended by an arc is twice the angle it subtends.
The diameter forms [tex]180^\circ[/tex] on the circle, so we have:
[tex]2*\theta = 180^\circ[/tex]
Where [tex]\theta[/tex] is the angle subtended
Solve for [tex]\thets[/tex][tex]\theta[/tex]
[tex]\theta = \frac{180^\circ}{2}[/tex]
[tex]\theta = 90^\circ[/tex]
During Christmas sale, a local store in Virginia has marked all items 20% off. George Walker bought a microwave that normally sells for $100 and a refrigerator that usually goes for $250. Calculate the total sale price.
Answer:
it looks like the answer to this problem is $280.
Step-by-step explanation:
i got this answer because you add $100 and $250 together. You will get $350. Then you take 20% of that total. So, 20% of 350 is 70. Now take 350-70, which = 280. and that should be your final answer.
what is the radius of the cylinder
Answer:
5.99
Step-by-step explanation:
brainliest pwease??
The volume of a cylinder can be found with the following equation
[tex]V = r^2h\pi[/tex]
After inputting the known information we get
[tex]980\pi = r^220\pi \\\\[/tex]
Which simplifies to
radius = 7 or (-7)
For proof's sake, we can try the equation again with the known radius
[tex]980\pi = r^220\pi \\980\pi = (7^2)20\pi \\980\pi = (49)20\pi \\980\pi = 980\pi \\[/tex]
And because the radius is being squared, it can either be negative or positive.

y = 2x
2y = 2(2x) = 4x
4x + x = -15
5x = -15
x = -3
You have 4 pounds of peanuts. You want to put it in the bags so that there is 2/3 pounds in each bag. How many bags can you fill ?
Answer:
6 bags
Step-by-step explanation:
This problem is essentially asking how many ([tex]\frac{2}{3}[/tex]) peanut bags can one fill with ([tex]4[/tex]) pounds of peanuts. This problem can be solved by divided ([tex]4[/tex]) by ([tex]\frac{2}{3}[/tex]). Set up the problem,
[tex]4[/tex] ÷ [tex]\frac{2}{3}[/tex]

The population of rabbits on an island is growing exponentially. In the year 2000, the
population of rabbits was 220, and by 2004 the population had grown to 350. Predict
the population of rabbits in the year 2011, to the nearest whole number.
Answer:
Step-by-step explanation:
630
Answer:
789 to nearest whole number.
Step-by-step explanation:
In 4 years its increased from 220 to 350.
350 = 220(e)^4k where k is some constant.
e^4k = 350/220
4k = ln (350/220) = 0.4643
k = 0.1161
The equation of growth is therefore
P = 220e^0.1161t)
So in 2011 ( t = 11 years) the
Population = 220 * e^(11*0.1161)
= 789.

Mark invests £12000 in a savings account. the account pays 1.5% compound interest per year. work out the value of her investment after two years?
Answer:
FV= £12,362.7
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= £12,000
Number of periods (n)= 2 years
Interest rate (i)= 1.5% = 0.015
To calculate the Future Value, we need to use the following formula:
FV= PV*(1 + i)^n
FV= 12,000*(1.015^2)
FV= £12,362.7

Answer:
A. -1
Step-by-step explanation:
To find the slope, subtract the x-coordinates, subtract the y-coordinates, lastly, divide the differences.
(3,1) (4,0)
3 - 4 = -1
1 - 0 = 1
-1 ÷ 1 = -1
-1 is the slope.
A certain bank offers a car loan with a fixed annual interest rate. Justine applied for the loan and used the entire amount to buy a car worth $43,000. He had to pay the bank for five years for a total amount of $51,600. How much would be the yearly interest if Justine borrowed $50,000 instead? *
0 points
Answer: $10000
Step-by-step explanation:
From the question,
Principal = $43000
Time = 5 years
Rate = Unknown
Simple Interest = $51,600 - $43000 = $8600
We need to calculate the rate of interest which will be:
Interest = PRT/100
8600 = (43000 × 5 × Rate) / 100
Cross multiply
8600 × 100 = 215000 × Rate
Rate = 860000 / 215000
Rate = 4%
Assuming Justine borrowed $50,000 instead, the yearly Interest will be:
= (50000 × 5 × 4%)
= 50000 × 5 × 0.04
= $10000

A water container in the shape of a cone has a height of 5 inches and a diameter of 3.5 inches.
Enter an equation in the first blank box and a number in the second blank box to complete the statements about the
water container ___.
A. The formula to calculate the container's volume, V, with the given measurements is
B. The container can hold approximately ___ cubic inches of water. Round your answer to the nearest hundreth.
Answer
A. The formula to calculate the container's volume, V, with the given measurements is ⅓ π(1.25²)5.
B. The container can hold approximately 8.177 cubic inches of water. Round your answer to the nearest hundredth.
Step-by-Step Explanation
A. The formula to calculate any cone's volume is ⅓ πr²h. Replace the variables with the actual values of the cone. r stands for the cone base's radius, or half of the diameter. Because the diameter is 3.5, the radius is 1.25, or half of it. The h stands for the height of the cone. Now we can plug in the values. Our answer for this part is ⅓ π(1.25²)5.
B. Now to solve our equation. [tex]1.25^2[/tex] is equal to 1.5625. Now, multiply by the height. 1.5625 x 5 is equal to 7.8125. We now multiply by [tex]\pi[/tex]. We'll use 3.14 to shorten the answer a bit. Multiply 7.8125 by 3.14 and you'll get 24.53125. Last but not least, divide this by 3 (or multiply by [tex]\frac{1}{3}[/tex]). [tex]\frac{24.53125}{3}[/tex] = 8.1770833333... We now must round this to the nearest hundredth. This makes our final answer 8.177 [tex]in^3[/tex].

My little brother needs help and tbh I forgot all abt this
Answer:
15
Step-by-step explanation:
Rectangle Formula:
a = b * w
a = area
b = base
w = width
Replace variables with numbers given:
375 = 25 * w
Divide both sides by 25
w = 15
