Isabella and Mateo each collect beautifully polished rocks. The weights, in ounces, of their rocks are listed below.



Which statistical measure could be used to support the claim that Mateo’s rocks generally weigh more than Isabella’s rocks?

Question 7 options:

A) mean


B) median


C) mode


D) range

Answers

In order to answer this question we have to find all the 4 measure, Mean, Median, Mode and Range of both data sets.

1) For the Rocks of Isabella:

Mean = (Sum of all numbers)/Total numbers
So, Mean weight of Isabella's Rocks = 7.64 

Median is the central value. 
So, Median weight of Isabella's Rocks = 6

Mode is the most frequently occurring value.
So, Mode weight of Isabella's Rocks = 8.75

Range = Maximum - Minimum
So, Range weight of Isabella's rocks = 13.75

2) For Mateo's Rocks:

Mean = 8
Median = 6
Mode = 8
Range = 14.75

From the above data, we can see that the Range of Mateo's Rocks is more as compared to the Isabella's Rocks.

Thus, Range can be used be used to support the claim that Mateo’s rocks generally weigh more than Isabella’s rocks.

So option D is the correct option

The circumference of a circle is approximately 37.7 centimeters. Enter the radius of the circle, in centimeters. Round your answer to the nearest whole number.

Answers

37.7 = 2 x pi x r
18.85 = pi x r
r = 18.85/pi
or 
r = 6

Hope this helps

The circumference of the circle is given as 2[tex] \pi [/tex]r where [tex] \pi [/tex] is a constant whose value is equal to 22/7 and r is the radius of the circle

From the given problem, we have the circumference =37.7

2[tex] \pi [/tex]r = 37.7

2*22/7*r = 37.7

r = 37.7*7/(22*2)

r = 263.9/44

r = 5.99

r = 6cm

Radius = 6 centimeters (Rounded to nearest whole number)


kendra flips a coin 3 times what is the probability that she flips tails all 3 times

Answers

If Kendra were to flip the coin only once, she'd have a fifty fifty chance (1/2). Two times for tails would be (1/2) again, since (1/4+1/4=1/2). Now, three times would be (1/6+1/6+1/6). This equals (1/2), so she remains at a 50% chance of flipping the coin three times.

To find the probability of flipping tails all three times, we need to consider that each flip of a fair coin has a probability of 0.5 of landing on tails.

Since the coin flips are independent events (the outcome of one flip doesn't affect the outcome of another flip), we can simply multiply the probability of each individual flip.

So, the probability of flipping tails three times in a row is:

P(Tails, Tails, Tails) = P(Tails) × P(Tails) × P(Tails)

P(Tails, Tails, Tails)  = 0.5 × 0.5 × 0.5

P(Tails, Tails, Tails) = 0.5³

P(Tails, Tails, Tails) = 0.125

So, the probability that Kendra flips tails all three times is 0.125 or18.

The probability of flipping tails on a fair coin is 0.5 (or 1/2) since there are two equally likely outcomes, heads or tails. When flipping a coin three times, each flip is independent, meaning the outcome of one flip doesn't affect the outcome of another.

To find the probability of flipping tails all three times, we multiply the probability of each individual flip.

So, 0.5 (tails on the first flip) times 0.5 (tails on the second flip) times 0.5 (tails on the third flip) equals 0.5³ = 0.125.

Therefore, the probability that Kendra flips tails all three times is 0.125 or 1/8.

Complete Question:

Kendra flips a coin 3 times what is the probability that she flips tails all 3 times.

genna painted a table top that is shaped like a circle . the circumferance of the tabletop is 6 feet which measurement is closest to the area of the tabletop in square feet?

Answers

To solve this problem you must apply the proccedure shown below:

 1. You must apply the formula for calculate the area of a circle, which is:

 A=πr^2

 Where A is the area of the circle and r is the radius of the circle.

 2. You have that the diameter is 6 feet, then the radius is:

 r=D/2
 r=3 feet

 3. When you apply the formula shown above, you obtain:

 A=9π feet^2
 A=28.27 feet^2

 The answer is: 28.27 feet^2
circumference  = 6 ft

circumference = 2*pi*r = 6
 
solve for r:
r = 6/(2*pi) = 0.9554 ft

area = pi*r^2 = 0.9554*0.9554 * 3.14 = 2.866 sq. ft

the ratio of boy to girls in 8th grade is 5 to 3 ,how many girls are there in 8th grade if there are 80 students in 8th grade

Answers

boys      5
------- = ---    Note that 5+3 = 8.  Thus, (5/8) of the 80 students are boys and 
girls       3     (3/8) of the 80 students are girls.  This comes out to 30 girls (and                         50 boys)  Note that 30+50=80 (students)

. Thus, the number of girls =30.

Let's denote the number of boys as 5x and the number of girls as 3x. According to the problem, the total number of students is the sum of both boys and girls:

5x + 3x = 80

Combining the terms, we get:

8x = 80

Now, solving for x:

x = 80 / 8

x = 10

Now that we know the value of x, we can find the number of girls:

Number of girls = 3x = 3 * 10 = 30

Therefore, there are 30 girls in the 8th grade.

a trapezoid with an area of 166.75 in has bases that measure 21 in and 8 in find the height of the trapezoid

Answers

The usual equation for a trapezoid is base1+base2/2 * height. For this, 21+8/2 equals to 166.75. Use division, and your height is 11.5

The area of trapezoid is calculated as -

Area of trapezoid = [tex] \frac{a + b}{2} X height [/tex]

Here, a = base 1

b = base 2

Height is the height of trapezoid.

It is given that,

Area of trapezoid = 166.75 in

Base 1, a = 21 in

Base 2, b = 8 in

Area of trapezoid = [tex] \frac{a + b}{2} X height [/tex]

166.75 in = [tex] \frac{21 in + 8 in}{2} X height [/tex]

Height = [tex] \frac{ 166.75 in}{14.5}

Height = 11.5 in

Thus, height of trapezoid = 11.5 In

Please solve both, graph and show work. answer also has to be in y=mx+b format.

ΔABC and ΔXYZ are similar triangles. If BA = x + 9, AC = x + 7, YX = x + 5, and XZ = x + 4, find the value of x.

Answers

Solution:

we are given that ΔABC and ΔXYZ are similar triangles.

As we know , when two triangles are similar then the ratios of their corrsponding sides are equal.

Here we have

BA = x + 9, AC = x + 7, YX = x + 5, and XZ = x + 4

So we can write

[tex] \frac{x+9}{x+5}= \frac{x+7}{x+4}\\ \\ (x+9)(x+4)=(x+7)(x+5)\\ \\ x^2+13x+36=x^2+12x+35\\ \\ 13x-12x=35-36\\ \\ x=-1\\ \\  [/tex]

Use absolute value to express the distance between −13 and 17 on the number line

Answers

Answer:

Step-by-step explanation:

Distance between two points a and b  using the absolute value is given by

|b-a|.

Here we have a=-13

and b =17

so

Distance = | 17- (-13) |

Distance = |17 +13 |

Distance = | 30 |

Distance = 30 units

In absolute value, the distance is written as |30|

The given points:

[tex](x_1, x_2) = (-13, 17)[/tex]

To find:

the distance between -13 and 17

The distance between the two points on a number line is calculated as;

[tex]Distance = \sqrt{(x_2-x_1)^2} \\\\Distance = \sqrt{(17--13)^2}\\\\Distance = \sqrt{(30)^2} \\\\Distance = + /- \ \ 30[/tex]

Answer:

Step-by-step explanation:

correct on edge 2021

The Equation have No solution is 4(x + 3) + 2x = 6(x + 2).

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

First, 4(x + 3) + 2x = 6(x + 2)

4x + 12 + 2x = 6x + 12

6x + 12 = 6x+ 12

0 = 0

Thus, the equation have No solution.

Second, 5 + 2(3 + 2x) = x + 3(x + 1)

5 + 6 + 6x = x + 3x + 1

6x+ 11 = 4x+ 1

2x = -10

x= -5

Thus, the equation have one solution.

Third, 5(x + 3) + x = 4(x + 3) + 3

5x+ 15 +x = 4x + 12 + 3

6x +15 = 4x + 15

2x = 0

x= 0

Thus, the equation have one solution.

The value of r that makes the expression 7r less than 7 is 4/5, as multiplying 7 by 4/5 results in 5.6, which is less than 7.

The question asks which value of r makes the expression 7r equal a number less than 7, given the choices of 4/4, 4/3, 4/5, or 4/1. To find the solution, we simply multiply 7 by each fraction option and see which results in a number less than 7.

For 4/4 (or 1): 7 * 1 = 7For 4/3: 7 * (4/3) > 7For 4/5: 7 * (4/5) = 5.6, which is less than 7For 4/1 (or 4): 7 * 4 > 7

Thus, the value of r that makes the expression 7r result in a number less than 7 is 4/5.
