Confidence interval of the dataThe confidence interval will help to determine if there is enough evidence in the statistical data draw conclusion that Vicente has the lead.
The confidence interval is 48% - 3% to 48% + 3%, which is equivalent to 45% to 51%.

Ordered pair for 3x + 5y = 2
9x + 11y = 14
Answer:
y = -3/5x +2 y = -9/11 + 14
Step-by-step explanation:
3x + 5y = 2(subtract 3x on both sides)
5y = -3x +2(divide by 5)
y = -3/5x + 2
9x + 11y = 14 (subtract 9x on both sides)
11y = -9x + 14 (divide by 11)
y = -9/11x + 14
Answer:
Step-by-step explanation:
-9x - 15y = -6
9x + 11y = 14
-4y = 8
y = -2
3x + 5(-2) = 2
3x - 10 = 2

Work out
x
, explaining each stage of your working in the comment box.
Based on the definition of isosceles triangle, the value of x in the given diagram is: 84°.
What is an Isosceles Triangle?An isosceles triangle has two base angles of equal length.
Given that, a = 22°, and using the information in the image attached below, we have the following:
m∠1 = a = 22° (base angles)
m∠2 = a + m∠1 = 22 + 22 = 44° (external angle theorem)
m∠3 = m∠2 =44° (base angles)
m∠4 = 180 - (180 - m∠2 - m∠3) - m∠1 = 180 - (180 - 44 - 44) - 22
m∠4 = 70°
m∠5 = m∠4 = 70° (base angles)
m∠6 = 180 - (180 - m∠5 - m∠4) - m∠3
m∠6 = 180 - (180 - 70 - 70) - 44
m∠6 = 96°
m∠7 = m∠6 = 96° (base angles)
x = 180 - m∠7
x = 180 - 96
x = 84°
Therefore, based on the definition of isosceles triangle, the value of x in the given diagram is: 84°.

Hannah randomly removes a chew from the bag, records the result, and returns the chew to the bag. Hannah performs the experiment 74 times. The results are shown below:
An orange chew was selected 39 times.
A lemon chew was selected 17 times.
A lime chew was selected 18 times.
Based on these results, express the probability that the next chew Hannah removes from the bag will be orange chew as a decimal to the nearest hundredth.
Based on these results, probability that the next chew Hannah removes from the bag will be orange chew is 0.53.
What is the probability of picking an orange chew?Probability determines how likely it is that event would occur. The probability that an event would occur lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
The probability of picking an orange chew = 39 / 74 = 0.53

The volume of two spheres are in the ratio 27:125. What is the ratio of their areas?
The volume of two spheres are in the ratio 27:125. The ratio of their areas is 9:25
If the volume of two spheres are in the ratio 27:125, then the ratio of their areas is 9:25.
How to compute the above ratioThe ratio of the volumes of two spheres is equal to the ratio of the cubes of their radii.
Therefore, if the volume ratio is 27:125, the radius ratio would be the cube root of that, which is 3:5.
The surface area of a sphere is given by the formula A = 4πr², where A is the surface area and r is the radius.
Since the radius ratio is 3:5, the ratio of their surface areas would be (3/5)² : 1², which simplifies to 9:25.
Therefore, the ratio of the surface areas of the two spheres is 9:25.

7 Jamila has a large toy box and a small toy box The large box is 120 cm long and 90 cm high. Each length of the small box is one-sixth the length of the large box
Write the length and height of the small box. Show your working
LENGTH of small box: .......cm
HEIGHT of small box: ......cm
Answer:
length = 20 cm
height = 15 cm
Step-by-step explanation:
Large Toy Box
length = 120 cmheight = 90 cmGiven:
Each length of the small toy box is one sixth of the corresponding lengths of the large toy box.Therefore, to calculate the length and height of the small toy box, multiply the length and height of the large toy box by one sixth:
[tex]\sf length=120 \times \dfrac16=\dfrac{120 \times 1}{6}=\dfrac{120}{6}=20 \ cm[/tex]
[tex]\sf height=90 \times \dfrac16=\dfrac{90 \times 1}{6}=\dfrac{90}{6}=15 \ cm[/tex]
Therefore,
length = 20 cmheight = 15 cmAnswer:
length = 20 cm , height = 15 cm
Step-by-step explanation:
calculate [tex]\frac{1}{6}[/tex] of the dimensions by dividing the large box dimensions by 6
length of small box = 120 cm ÷ 6 = 20 cm
height of small box = 90 ÷ 6 = 15 cm

The GCF of 12 and 28 is _____.
greatest common factor 12 and 28 is 4
The greatest common factor (GCF) of 12 and 28 is 4.
To find the GCF, you can determine the factors of both numbers and identify the greatest common factor they share.
As we know that a factor is a number that entirely divides another number.
To put it another way, any two integers that multiply to generate a result are factors of the result.
For 12, the factors are 1, 2, 3, 4, 6, and 12.
For 28, the factors are 1, 2, 4, 7, 14, and 28.
The common factors of 12 and 28 are 1, 2, and 4.
Among them, the greatest common factor is 4.
Therefore, the GCF of 12 and 28 is 4.

In the game of Pick-A-Ball, there are 10 colored balls: 2 red, 4 white, and 4 blue. The balls have been placed into a small bucket, and the bucket has been shaken thoroughly. You will be asked to reach into the bucket without looking and select 2 balls. Because the bucket has been shaken thoroughly, you can assume that each individual ball is selected at random with equal likelihood of being chosen. It is common in games of chance to be rewarded for obtaining unlikely results. For example, in the game of poker, hands that are less likely to occur tend to trump hands that are more likely to occur. That same concept applies in this game. It costs $10 to play Pick-A-Ball, and your prize is the reciprocal of the probability of obtaining your exact sequence of results, expressed in dollars. For example, if the probability of obtaining your exact sequence of results is 0.10, your prize is 1/0.10
Required:
What is the probability of selecting the color of ball that you just selected?
Answer:
The probability of selecting the color of ball that you just selected(a red ball) is [tex]P(r) = \frac{2}{10}[/tex]
Step-by-step explanation:
From the question we are told that
The total number of colored balls is n = 10
The number of red balls is r = 2 red
The number of white ball is w = 4
The number of blue balls is b = 4
The number of balls to be selected is N = 2 balls
The cost of playing picking a ball is c = $10
The winnings is [tex]k = \$ P(A)[/tex]
Here P(A) is the probability of obtaining the exact sequence of result and from the question it is P(A) = 0.10
Generally my price according to the question is
[tex]k = \frac{0.10 }{10}[/tex]
=> [tex]k = 0.01 [/tex]
Let assume we selected a red ball
Generally the probability of selecting a red ball is mathematically represented as
[tex]P(r) = \frac{2}{10}[/tex]
