Of the marbles in a bag, 5 are blue, 2 are white, and 2 are yellow. Sandra will randomly choose one marble from the bag.
Answer:
[tex]\dfrac{2}{9}[/tex]
Step-by-step explanation:
Given that,
A bag contains 5 blue, 2 white and 2 yellow marbles.
We need to find the probability of choosing a white marble from the bag.
Total no. of outcomes = 5+2+2
= 9
No. of white marbles = 2
Required probability,
[tex]P=\dfrac{2}{9}[/tex]
So, the probability of choosing a white marble is equal to [tex]\dfrac{2}{9}[/tex].

Which of the following equations has a solution x = 4? Select all that apply.
0-2 (32 – 4) = -16
{(100 + 2) = 6
20 - 15x = 6 - 2 (4x + 7)
(90 - 12) +6 = -10
Answer:
[tex]-2(3x - 4) = -16[/tex] and [tex]20- 15x = 6 - 2(4x + 7)[/tex]
Step-by-step explanation:
Given
[tex]-2(3x - 4) = -16[/tex]
[tex]\frac{1}{2}(10x + 2) = 6[/tex]
[tex]20- 15x = 6 - 2(4x + 7)[/tex]
[tex]\frac{1}{3}(9x - 12) + 6=-10[/tex]
Required
Equations with [tex]x = 4[/tex] as a solution
[tex]-2(3x - 4) = -16[/tex]
Divide both sides by -2
[tex]3x - 4 = 8[/tex]
Add 4 to both sides
[tex]3x - 4 +4= 8+4[/tex]
[tex]3x =12[/tex]
Divide both sides by 3
[tex]x = 4[/tex]
[tex]\frac{1}{2}(10x + 2) = 6[/tex]
Multiply both sides by 2
[tex]10x + 2 = 12[/tex]
Subtract 2 from both sides
[tex]10x + 2 -2= 12-2[/tex]
[tex]10x = 10[/tex]
Divide both sides by 1
[tex]x = 1[/tex]
[tex]20- 15x = 6 - 2(4x + 7)[/tex]
Open bracket
[tex]20 - 15x = 6 - 8x - 14[/tex]
Collect like terms
[tex]8x - 15x = 6 - 14 - 20[/tex]
[tex]-7x = -28[/tex]
Divide both sides by -7
[tex]x = 4[/tex]
[tex]\frac{1}{3}(9x - 12) + 6=-10[/tex]
Subtract 6 from both sides
[tex]\frac{1}{3}(9x - 12) + 6-6=-10-6[/tex]
[tex]\frac{1}{3}(9x - 12) =-16[/tex]
Multiply both sides by 3
[tex]9x - 12 = -48[/tex]
Add 12 to both sides
[tex]9x - 12 +12= -48+12[/tex]
[tex]9x = -36[/tex]
Divide both sides by 4
[tex]x =-4[/tex]
[tex]-2(3x - 4) = -16[/tex] and [tex]20- 15x = 6 - 2(4x + 7)[/tex] have [tex]x = 4[/tex] has a solution

The price of a train season ticket increased by 4%.
The price of the ticket increased by £ 152.20
Work out the price of the train ticket before the increase.
The original price of the train ticket will be £3805.
What is the percentage?The Percentage is defined as representing any number with respect to the 100. It is denoted by the sign %.
Given that:-
The price of a train season ticket increased by 4%.The price of the ticket increased by £152.20The original price will be calculated as:-
4 % = 152.20
1 % = 152.20 / 4
1 % = 38.05
So 100 percent will be calculated by multiplying by 100 on both sides.
100 % = 38.05 x 100
100% = 3805
Therefore the original price of the train ticket will be £3805.

The question is in the image
Answer:
2.2 miles
Step-by-step explanation:
Coordinates of Joe's home = (2, 3)
Coordinates of the park = (1, 1)
The shortest distance = the distance between the two points
Use distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex] to calculate the shortest distance.
Where,
[tex] (2, 3) = (x_1, y_1) [/tex]
[tex] (1, 1) = (x_2, y_2) [/tex]
Plug in the values into the formula
[tex] d = \sqrt{(1 - 2)^2 + (1 - 3)^2} [/tex]
[tex] d = \sqrt{(-1)^2 + (-2)^2} [/tex]
[tex] d = \sqrt{1 + 4} [/tex]
[tex] d = \sqrt{5} [/tex]
[tex] d = 2.2 [/tex] (nearest tenth)
Shortest distance between Joe's home and the park = 2.2 miles

Answer: The answer is b !
Image attached should help
The line of best fit is:
y = 3.1x + 12.9
Option A is the correct answer.
We have,
The line of best fit can be expressed in the form of y = ax + b,
where a is the slope of the line and b is the y-intercept.
From the given LinReg results, we have:
a = 3.1
b = 12.9
Substituting a and b in the equation y = ax + b we get,
The line of best fit is:
y = 3.1x + 12.9
Thus,
The line of best fit is:
y = 3.1x + 12.9

Answer:
the mean is 6
the median is 6
the mode there is none
the range is 6.
Answer:
There is no mode. (they all appear once)
The lowest number is 3 and the highest is 9, so the range is 6.
The mean is the average, add them all up (30) and divide by the number of data sets (5). The average is 6.

Complete Question
Use a ratio box to solve this problem the ratio of new pens to used pens was 4 to 7 in all there were 242 pens, how many new pens were in the box?
Answer:
88 new pens
Step-by-step explanation:
The ratio of new pens : Old pens = 4:7
Sum of Proportion = 4 + 7 = 11
Total number of pens = 242 pens
The number of new pens is calculated as:
4/11 × 242 pens
= 88 new pens
Therefore, the number of new pens = 88 new pens
