Answer:
Avoid histograms with small bin widths that group data into lots of bins. A histogram constructed with small bin widths will show the distribution as a “pancake.” so no it does not help us see the pattern in the data.

Factorise x² - 9x + 20
Step-by-step explanation:
Given
x² - 9x + 20
= x² - ( 4 + 5) x + 20
= x² - 4x - 5x + 20
= x ( x - 4) - 5 ( x - 4)
= (x - 4)(x - 5)
Hope it will help you :)

Answer:
3/2
Step-by-step explanation:
the equation to find the slope is (y2 - y1) / (x2 - x1) so if you plug in the two points (9 - 6) / (3 - 1) you get 3/2
Answer:
[tex]\huge\boxed{\text{Slope: } \frac{3}{2}}[/tex]
Step-by-step explanation:
In order to solve for the slope between two points, we need to note that the slope between two points will be the change in y divided by the change in x, more commonly represented by this formula.
[tex]\frac{\Delta y}{\Delta x}[/tex]
We can find the change in y and change in x by subtracting the second values from the first values.
The second y value is 9, and the first is 6, so the total change is [tex]9 - 6 = 3[/tex].
The second x value is 3, and the first is 1, so the total change is [tex]3 - 1 = 2[/tex].
We divide the change in y by the change in x:
[tex]\frac{3}{2}[/tex]

Answer:
F = k/d^2
Step-by-step explanation:
We can see from the question that the force of attraction F is proportional to the inverse of the square of the distance separating the bodies, d.
So we have;
F α 1/d^2
So, introducing a constant of proportionality k,
F = k/d^2
Hence the formula connecting F and d is; F = k/d^2

Answer:
1a. 64=4(7+x)
1b. x=9
2a. 64=7+4x
2b. x=57/4
Step-by-step explanation:
1a. To represent this situation, all of the weight for each package must be in the equation. Since each package has 4 boxes, and only the objects in one box are detailed, everything must be multiplied by 4. Now, the values that must be multiplied by 4 are a bag of rice and beans. Since the beans weigh 7 pounds, they can be represented using the constant 7, and the rice can be represented with the variable x. Combining all of this information, the equation 64(total)=4(7+x)
1b. Now, the equation above must be solved. First, divide both sides by 4 in order to get 16=7+x. Now, subtract 7 from both sides to find that x=9
2a. This problem is similar to the first problem, except instead of multiplying both the beans and rice by four, only the rice needs to be multiplied. With this knowledge the equation 64=7+4x is created.
2b. To solve the above equation, 7 must be subtracted from both sides. This leaves 57=4x. Now, both sides must be divided by 4, giving the final answer of x=57/4.
Answer:
1a. 64=4(7+x)
1b. x=9
2a. 64=7+4x
2b. x=57/4

To factor the expression 3x2 – 9x, Caleb found the GCF as shown. List the factors: 3x2 = 3 • x • x 9x = 3 • 3 • x GCF = 3 • 3 • x • x = 9x2 What is Caleb’s error? Caleb factored 3x2 incorrectly. Caleb factored 9x incorrectly. Caleb found the product of all factors, not just the ones common to each term. Caleb did not make an error.
Answer:
Caleb found the product of all factors, not just the ones common to each term.
Step-by-step explanation:
answer
Caleb found the product of all factors, not just the ones common to each term. Then the correct option is C.
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The expression is given below.
⇒ 3x² – 9x
The factor of 3x² will be 3 · x · x.
The factor of 9x will be 3 · 3 · x.
GCF = 3 • 3 • x • x = 9x²
Caleb found the product of all factors, not just the ones common to each term.
Then the correct option is C.

Write your answer as a fraction in simplest form.
Answer:70/100 or 7/10
Step-by-step explanation:
one hour is 60 mins
1/5 of an hour is 12 mins
1/2 of an hour is 30
30 + 12 = 42
42/60 simplified is 7/10

What is the length of arc S shown below?
Enter an exact expression.
Answer:
The length of the arc is 1.6 cm
Step-by-step explanation:
To find the value of the length of the arc, we use the length of arc formula
Mathematically, this is;
theta/360 * 2 * pi * r
where theta is the central angle
In this case pi/4 = 180/4 = 45 degrees
r = 2 cm
So the measure of the length of the arc will be;
L = 45/360 * 2 * 22/7 * 2
= 1/8 * 4 * 22/7
= 22/7 * 1/2 = 11/7 = 1.57 cm which is approximately 1.6 cm
