What is the diameter of a 2m circle?
Answers
Answer:
If 2m is the radius, the diameter is 4 meters.
2*2=4
2*2=4
Explanation
The diameter of a circle is the distance from one edge to the other, passing through the center. It is twice the radius.
So the diameter would be 2 cause 2 x 2=4

A quadratic equation, y = ax^2 - 6x + 10, has exactly one real root. Calculate the value of a.
Answers
Answer:
a = 0.9
Step-by-step explanation:
For the quadratic equation \(\boxed{ax^2 + bx + c = 0}\) to have exactly one real root, the value of its discriminant, \(\boxed{b^2 - 4ac}\), must be zero.
For the given equation:
\(y = ax^2 - 6x + 10\),
• a = a
• b = -6
• c = 10.
Substituting these values into the formula for discriminant, we get:
\((-6)^2 - 4(a)(10) = 0\)
⇒ \(36 - 40a = 0\)
⇒ \(36 = 40a\)
⇒ \(a = \frac{36}{40}\)
⇒ \(a = \bf 0.9\)
Therefore the value of a is 0.9 when the given quadratic has exactly one root.

In order for Mateen to walk a kilometer(1000m) in his rectangular backyard, he must walk the length 25 times or walk its perimeter 10 times. What is the area of Mateen's backyard in square meters
Answers
Answer:
400
Step-by-step explanation:
25 times the length is 1000 m.
Let length = L
25L = 1000
L = 40
10 times the perimeter is 1000 m.
Let the perimeter = P
10P = 1000
P = 100
perimeter = 2L + 2W
2(40) + 2W = 100
80 + 2W = 100
2W = 20
W = 10
The length is 40 m, and the width is 10 m.
A = LW
A = 40 m * 10 m
A = 400 m^2

A physical education department wanted a single test of upper body strength that was easy to administer. Dips on the parallel bars and pull-ups on the horizontal bar were considered good tests. One faculty member thought that both tests were not needed because the correlation between the two was probably high. To evaluate this assumption, 141 students were tested on both criteria. The faculty member let X represent dips on the parallel bars and Y represent pull-ups and calculated the following from the data:
ΣX = 3,416, ΣY = 1,899, SDX = 8.84, SDY = 4.70, ΣZXZY = 109.416.
Calculate the following:
a. The mean of each variable
b. The correlation between the two variables
c. The level of confidence and the p value reached by the coefficient
d. The predicted number of pull-ups for a student who performed 20 dips
e. The standard error of the estimate
f. The predicted range of possible pull-up scores at the 95% LOC for a student who performed 20 dips
Answers
Answer:
24.23 ; 13.47 ; 0.782 ; p value < 0.00001 ;7.45
Step-by-step explanation:
Given that :
ΣX = 3,416, ΣY = 1,899, SDX = 8.84, SDY = 4.70, ΣZXZY = 109.416
Sample size, N = 141
Mean of X:
£X / N = 3416 / 141 = 24.23
Mean of Y:
£Y / N = 1899 / 141 = 13.47
B.) Correlation between the 2 variables :
£ZXZY / N - 1
= 109.416 / 140
= 0.782
C.)
Level of significance and p value :
T = [Rsqrt(n-2)] ÷ sqrt(1 - R²)
T = [0.782 * sqrt(139)] ÷ sqrt(1-0.782^2)
T = 14.79
P value from Tscore calculator
Df = 141 - 2 = 139 ; α = 0.05
Pvalue = 0.00001
Pvalue < α ; Hence, a significant positive relationship exists.
To obtain regression model :
Slope = £ZXZY / SDX²
m = 109.416 / 8.84^2 = 1. 4
yintercept = meanY - slope*x
yintercept = 13.47 - 1.4*24.3
yintercept = - 20.55
Equation in slope intercept form:
y = mx + c
y = 1.4x - 20.55
For x = 20
y = 1.4(20) - 20.55
y = 7.45

Can credit a customers account up to 20% of full amount due. Customers bill is 333.00, I could offer a credit of?
Answers
I could offer a credit of $66.6.
What is percentage?A percentage is a number or ratio expressed as a fractin of 100. It is often denoted using a percent "%" sign.
The given bill of customer = $333.0.
Credit can be given to customer = 20%
Now,I can credit a customers account up to 20% of full amount due
For credit off to be offer,we need to find 20% of $333
⇒ 20% of $333 = 20/100*333
⇒ 20% of $333 = $66.6
Hence, I could offer a credit of $66.6

B. The amount is 4.8, the base is 12, and the percent is unknown.
C. The amount is unknown, the base is 4.8, and the percent is 12 %
D. The amount is unknown, the base is 12, and the percent is 4.8%
Answers
The amount is 4.8, base is 12 and the precent of the given condition is unknown.
Define base:
In mathematics, the term "base" refers to a fixed number or symbol used as a point of reference for counting, measuring or representing a quantity.
In the decimal system, for example, the base is 10, because there are 10 possible digits (0-9) that can be used to represent a number. In binary system, the base is 2, because there are only 2 possible digits (0 or 1) that can be used to represent a number.
What about precent?
In mathematics, percent is a way of expressing a number as a fraction of 100. The term "percent" means "per hundred," so a number expressed as a percent represents a fraction of 100.
To convert a number to a percent, we multiply it by 100. For example, if we want to express the number 0.25 as a percent, we can multiply it by 100 to get:
⇒ 0.25 x 100 = 25%
According to the given information:
Percent: The precent is the number with the % symbol
Base: The base is the whole amount which in this case is 12.
Amount: The amount based on the precent is 4.8
So, from overall condition we have that option 'a' is correct.

If f(x) = 16x – 30 and g(x) = 14x – 6, for which value of x does (f – g)(x) = 0? –18 –12 12 18
Answers
Answer:
Option 3: 12 is the correct answer.
Step-by-step explanation:
Given functions are:
\(f(x) = 16x-30\\g(x) = 14x-6\)
In order to find the value of x on which (f-g)(x) will be zero, first of all we have to find (f-g)(x) and then equate it equal to zero to find the value of that will make (f-g)(x)
So,
\((f-g)(x) = f(x) - g(x)\\= (16x-30)-(14x-6)\\=16x-30-14x+6\\= 2x-24\)
Now to find the value of x on which (f-g)(x) will be zero, putting (f-g)(x) = 0
\((f-g)(x) = 0\\2x-24 = 0\)
Adding 24 on both sides
\(2x-24+24 = 0+24\\2x = 24\)
Dividing both sides by 2
\(\frac{2x}{2} = \frac{24}{2}\\x = 12\)
For x=12, (f-g)(x) will be zero.
Hence,
Option 3: 12 is the correct answer.

hi ! I really need help understanding paragraph and I've also added a question about paragraph by me down below . Would like explanation in simple words.
If answers correct I'll rate you five stars a thanks and maybe even brainliest
Paragraph I needed help understanding:
If two or more cells are connected together side by side, the voltage across them is sum of the voltage of each cell. This is because both cells are pushing same way.
My Question about paragraph:
If the sum lets say was 4.5v would every individual cell be worth 4.5 as it says in question ' voltage across them is the sum of voltage of each cell ' or are they each a different value? And how would we be able to find value?.
Answers
If the sum of the voltage is 4.5V, it is possible that different cells have different voltages. For example, three cells with voltages 1V, 1.5V, and 2V could be connected together side by side to give a total voltage of 4.5V.
To find the voltage of each cell, we would need to know the voltage across each cell or the voltage of the other cells connected in the circuit. Then we could use the fact that the sum of the voltages across all cells in the circuit is equal to the total voltage of the circuit to solve for the voltage of each cell.

write an equation in point slope form that represents a line that passes by (-9,-2) and has a slope of -4
Answers
Answer:
\(y+2=-4(x+9)\)
Step-by-step explanation:
Point-slope form: \(y-y_1=m(x-x_1)\)
We can write the equation by plugging in the x and y coordinates in the point (-9, -2).
\(y-y_1=m(x-x_1)\\y-(-2)=m(x-(-9))\)
Two negatives make a positive
\(y+2=m(x+9)\)
Now, we can plug in the slope, -4, as m.
\(y+2=m(x+9)\\y+2=-4(x+9)\)
I hope this helps!
