2.) 1/6 Chance of rolling a 7 due to having 6 total numbers and only one 7
3.) 10/52 Chance of pulling green due to only having 10 green marbles and 52 total marbles
Answer 2

Answer:

Probability that the chosen letter is d is [tex]\frac{1}{6}[/tex]Probability of rolling a 7 is [tex]\frac{1}{6}[/tex]Probability of picking a green is [tex]\frac{5}{21}[/tex]

Step-by-step explanation:

Probability of choosing d in the word "combed"

Given:

Alphabet: d

Word: combed

First, we note down the length of the word "combed";

The length is 6 characters

The we check the number of occurrence of d in the word "combed"

Occurrence of d = 1

Probability is then calculated as;

Probability of choosing d = [tex]\frac{Number of Occurrence}{Total Observation}[/tex]

By Substitution; Probability = [tex]\frac{1}{6}[/tex]

Probability of rolling a 7 in a cube of side numbers 2,4,8,9,4, and 7

Given:

Roll number = 7

Sample Space= {2,4,8,9,4, 7}

Sample Size, n(S) = 6

We check the number of occurrence of 7 in the sample space

Number of occurrence = 1

Probability is then calculated as;

Probability of rolling a 7 = [tex]\frac{Number of Occurrence}{Sample Size}[/tex]

By Substitution; Probability = [tex]\frac{1}{6}[/tex]

Probability of pulling out a green marble

Given

Red = 12

Green = 10

Yellow = 2

Blue = 19

Purple = 9

Total = 12 + 10 + 2 + 19 + 9 = 42

Probability of picking a green marble is then calculated as;

Probability of choosing d = [tex]\frac{Number of Green}{Total}[/tex]

By Substitution; Probability = [tex]\frac{10}{42}[/tex]

Probability = [tex]\frac{5}{21}[/tex]

The length of a rectangle is five times its width. The perimeter of the rectangle is at most 96 cm. Which inequality models the relationship between the width and the perimeter of the rectangle?
2w+2⋅(5w)>96
2w+2⋅(5w)<96
2w+2⋅(5w)≤96
2w+2⋅(5w)≥96

Answers

Let

L--------> the length of the rectangle

W-------> the width of the rectangle

we know that

the perimeter of the rectangle is equal to

[tex]P=2L+2W[/tex]

[tex]P\leq 96\ cm[/tex]

so

[tex](2L+2W)\leq 96[/tex] ---------> equation [tex]1[/tex]

[tex]L=5W[/tex] ---------> equation [tex]2[/tex]

Substitute equation [tex]2[/tex] in equation [tex]1[/tex]

[tex]2*(5W)+2W\leq 96[/tex]

therefore

the answer is the option

3x+1/5 y= 7 solve for x

Answers

x = -1/15y+7/3

I hope this helps! :>
3x + 1/5y = 7

To solve for a variable, you have to isolate the variable that you want to solve. In this case, we want to solve for "x," so we must isolate "x."

So, subtract 1/5y from both sides.

3x = -1/5y + 7

Then, divide both sides by 3.

3x ÷ 3 = (-1/5y + 7) ÷ 3

Simplify.

x = -1/15y + 7/3

Whats 95 closer to 64 or 125

Answers

125-95=30
95-64=31
so it would be 125

To find out if 95 is closer to 64 or 125, we compare the absolute differences. 95 is 31 units away from 64 and 30 units away from 125. Therefore, 95 is closer to 125.

To determine whether 95 is closer to 64 or 125, we need to calculate the absolute differences between 95 and each of the two numbers:

Difference between 95 and 64: |95 - 64| = 31Difference between 95 and 125: |125 - 95| = 30

Since 30 is smaller than 31, 95 is closer to 125 by 1 unit.

Joaquin recorded a temperature of 62°F this morning for science class. The temperature increased 6 1/2°F in the afternoon before decreasing 8.7°F in the evening. What was the evening temperature?

Answers

Add 6.5 to 62 then subtract 8.7 to get 59.8

Answer: [tex]59.8^{\circ} F[/tex]

Step-by-step explanation:

Given : Joaquin recorded a temperature of 62°F this morning for science class.

The temperature increased [tex]6\dfrac{1}{2}^{\circ}F[/tex] in the afternoon before decreasing 8.7°F in the evening.

We can write [tex]6\dfrac{1}{2}[/tex] as [tex]6+\dfrac{1}{2}=6+0.5=6.5[/tex]  .

Now According to the question , the temperature at evening will be :-

[tex]62^{\circ}F+6\dfrac{1}{2}^{\circ}F-8.7^{\circ}F\\\\=62^{\circ}F+6.5^{\circ}F-8.7^{\circ}F\\\\=(62+6.5-8.7)^{\circ}\ F=59.8^{\circ}\ F[/tex]

Hence, the evening temperature was [tex]59.8^{\circ} F[/tex] .

A student wants to find the density of an egg as part of an experiment. If the weight of the egg is 57 g, and its volume is 48.25 mL, which measurement could be the most precise value of the density of the egg, in g/mL?

Answers

Remember that
[tex]density=\frac{mass}{volume}[/tex]

We have a mass of 57g and a volume of 48.25mL, so then:
[tex]density=\frac{57g}{48.25mL}[/tex]

The most precise value of the density of the egg will be 1.18 g / mL.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

Weight of the egg = 57 g

Volume = 48.25 mL

Now,

Since, Weight of the egg = 57 g

Volume = 48.25 mL

We know that;

⇒ Density = Mass / Volume

Substitute all the values, we get;

⇒ Density = 57 g / 48.25 mL

                = 1.18 g / mL

Thus, The density of the egg = 1.18 g/mL

A high school had 740 students at the start of the year, but then some students left the school. After that, the school had 726 students. If s = the number of students who left the school, which mathematical sentence expresses the information above? A. 740 - s = 726 B. s - 740 > 726 C. s - 740 = 726 D. 740 - s > 726

Answers

Answer:

A. 740 - s = 726

Step-by-step explanation:

The equation states: the original number of students, subtracting the number of students that left, represents the number of students now.

Correct option is (A) 740 - s = 726

Given that a high school had 740 students at the start of the year.

However some students left the school. After that, the school had 726 students.

Let 's' be the  the number of students who left the school

Thus as 's' students left the school, there will be deduction of 's' students from the school

Now this deduction 's' would be from the 740 students which were present in the school and the resultant students after deduction is given to be '726'

Thus we can form the mathematical expression as follows,

[tex]740 - s = 726[/tex]

Thus '740 - s = 726' is the requires expression
