A large jar contains an unknown number of red gumballs and 145 green gumballs. As part of a seventh-grade class project the teacher asks Carlos to estimate the total number of gumballs in the jar using a sample. Carlos draws a sample of 55 gumballs, of which 11 are red and 44 are green. Use Carlos' sample to estimate the number of gumballs in the jar.
Answers
The total number of gumballs in the jar calculated using probability is about 181.
Probability is the study of chance. The likelihood of an event to occur given as a fraction is probability.
For a sure event the probability is 1 and for an impossible event the probability is 0.
Carlos draws a sample of 55 gumballs. Out of which the number of green gumballs is 44.
Probability of a green gumball= number of green gumballs ÷ total number of gumballs
P(green) = 44 ÷ 55 = 4/5
Now in the sample the number of green gumballs is 4/5 , and in the jar the number of green gumballs is 145 .
Let us consider there are x gumballs in total in the jar.
P(green)=145 ÷ x
We know that P(green)= 4/5
∴4/5 = 145 ÷ x
or, x = 145 × 5 ÷ 4
or, x = 181.25 gumballs.
or, x ≈ 181 gumballs(As the number of gumballs cannot be a fraction)
Therefore there are about 181 gumballs in total .

using properties of the type of triangle you have identified (isosceles) (QR and RS are equal), set up a problem and solve for x
Q: 8x-17
R: 19x+4
S: 5x+1
Answers
The required required value of angles are 31, 118, 31.
Explain isosceles triangle.An Isosceles triangle is a triangle that has two equal sides. Also, the two angles opposite the two equal sides are equal. In other words, we can say that “An isosceles triangle is a triangle which has two congruent sides“.
According to question:We have,
∠Q = 8x-17, ∠R = 19x+4, ∠S = 5x+1
So,
∠Q + ∠R + ∠S = 180
= 8x-17 + 19x+4 + 5x+1
= 32x - 12 = 180
= 32x = 192
x = 6
Angles are;
∠Q = 8x-17 = 8(6)-17 = 31
∠R = 19x+4 = 19(6)+4 = 118
∠S = 5x+1 = 5(6)+1 = 31
Thus, required value of angles are 31, 118, 31.

Write an equation that represents the line
Answers
Answer:
Well an equation for a linear equation would be in The format
y= mx + b
With the only importance here is M being the slope and the B being the y-intercept.
We can’t have an exact estimate of the Y intercept so we can use point slope formula which is a build up of y=mx+b or you can just subsitute, I’ll go over both ways.
Point slope solution
Point slope formula is
y-y1 = m(x-x1)
1 does not impact the form, it’s a label.
(x1,y1) is the first coordinate which can also be any LABELED so lets do (4,6).
M represents slope.
To count slope we need to follow the formul
y2-y1 / X2-x1
Now solve.
6-1/ 4- (-2)
5/6 is the slope here.
So plugging everything into point slope formula.
y - 6 = 5/6 ( x - 4)
Solve.
Isolate the equation into y=mx + b
y = 5/6x + 2 2/3 is your final equation.
Slope intercept solution
Well this is just the name.
Plus in everything you know into y=mx + b
We know that the slope (m) is 5/6
(x,y) can be any point on the line so lets use (4,6)
We solve for b (y- intercept)
So…
6 = 5/6 (4) + b
Solve
6= 20/6 +b
2 2/3 = b
Now plug it in normally.
Y= 5/6x + 2 2/3

2) Lin and Andre biked home from school at a steady pace. Lin biked 1.5 km and it took her 5 minutes. Andre biked 2 km and it took him 8 minutes,
Answers
a. To find Lin's rate, we will divide the total distance that she biked by the time she took to cover that distance.
Given that:
distance = 1.5 km
time = 5 minutes
\(\text{rate}=\frac{\text{distance}}{\text{time}}=\frac{1.5\operatorname{km}}{5\min}=0.3\operatorname{km}\/\min \)This means that Lin's unit rate is 0.3 km/min.
b. The point that would represent Lin's unit rate would be at ( 1, 0.3 )
c. To find Andre's rate, we will be using the same method we used to find Lin's rate.
Given that:
distance = 2 km
time = 8 minutes
\(\text{rate}=\frac{\text{distance}}{\text{time}}=\frac{2\operatorname{km}}{8\min }=0.25\operatorname{km}\/\min \)d. The point that would represent Andre's unit rate would be at ( 1, 0.25 )

MARK ME BRAINLIEST PLZZZZZZZZZZZZZZZA study of the amount of time it takes a mechanic to rebuild the transmission for a 1992 Chevrolet Cavalier shows that the mean is 8.4 hours and the standard deviation is 1.77 hours. Assume that a random sample of 40 mechanics is selected and the mean rebuild time of the sample is computed. Assuming the rebuilding times are normally distributed, what percentage of sample means is greater than 8.8 hours? Express your answer as a percent rounded to hundredths of a percent.
Answers
Using the normal distribution, it is found that 7.64% of of sample means are greater than 8.8 hours.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean \(\mu\) and standard deviation \(\sigma\) is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).The parameters are given as follows:
\(\mu = 8.4, \sigma = 1.77, n = 40, s = \frac{1.77}{\sqrt{40}} = 0.2799\)
The proportion of sample means greater than 8.8 hours is one subtracted by the p-value of Z when X = 8.8, hence:
\(Z = \frac{X - \mu}{\sigma}\)
By the Central Limit Theorem
\(Z = \frac{X - \mu}{s}\)
\(Z = \frac{8.8 - 8.4}{0.2799}\)
Z = 1.43
Z = 1.43 has a p-value of 0.9236.
1 - 0.9236 = 0.0764.
7.64% of of sample means are greater than 8.8 hours.

Write 18 hundreds 11 tens in standard form.
Answers
The standard form of "18 hundreds 11 tens" is 1910.
To write "18 hundreds 11 tens" in standard form, we need to convert the given number into its numerical representation.
We know that 1 hundred is equal to 100, and 1 ten is equal to 10.
So, to find the numerical value of "18 hundreds 11 tens," we multiply the respective values by their place values and then add them together.
18 hundreds = 18 x 100 = 1800
11 tens = 11 x 10 = 110
To find the standard form, we add the two values:
1800 + 110 = 1910
Therefore, "18 hundreds 11 tens" in standard form is 1910.
In standard form, numbers are written using digits, without any reference to place value units like hundreds or tens.
The standard form of a number represents its numerical value directly. So, the numerical value of "18 hundreds 11 tens" is 1910, which is its standard form.

Answers
from 0 hr to 2 hr in the graph, the height of the snow after a snowfall is changed 0 to 2 inches of snow,
so this relation between the 0 to 2 hr is a proportional relationship. and the rate of snowfall between these hours is 1 inch of snow per hour.
From 2 to 5 hours the height of the snow is constant, so there is now snowfall in between 2 to 5. so the rate of snowfall is 0 in between 2 to 5 hrs
from 5 to 6 hr,
the height of snow increases proportionally to the time. it means there is a proportional relation between 5 to 6 hr

Joel wants to buy a new tablet computer from a store having a 20% off sale on all tablets. The tablet he wants has an original cost of $190. He also wants to make sure he has enough money to pay the 5% sales tax. How much will Joel pay for the tablet?
Answers
Answer:
161.5 $
Step-by-step explanation:
the cost of table after the discount = 100% - 20% = 80%
the cost of table after the discount = Original cost × 80%
=(190)(0.8)
=152 $
the cost of table after the discount plus the tax = (the cost of table after the discount) + (Original cost × 5%)
=152+(190)(0.05)
=152+9.5
=161.5 $
So... The total amount will Joel pay for the tablet = 161.5 $
You take the original asking price ($190) you find 20% of 190 which is 38. Then you subtract 38 from 190 you get 152. Next you do 5% of 152 and you get 7.95. Finally you add 7.95 to 152 and you get 166.95.

Determine whether the graph of the equation is symmetric with respect to the x axis, y axis and or the origin.
X^2 + Y -36 =0
Answers
The graph of the equation x² + y - 36 = 0 is symmetric with respect to the y-axis and the origin, but not with respect to the x-axis.
x² + y - 36 = 0
Symmetry with respect to the x-axis:
Replace y with -y: x² - y - 36 = 0
This equation is not equivalent to the original equation, so the graph is not symmetric with respect to the x-axis.
Symmetry with respect to the y-axis:
Replace x with -x: (-x)² + y - 36 = 0
Simplifying, we get x² + y - 36 = 0, which is equivalent to the original equation.
Therefore, the graph is symmetric with respect to the y-axis.
Symmetry with respect to the origin:
Replace x with -x and y with -y: (-x)² + (-y) - 36 = 0
Simplifying, we get x² + y - 36 = 0, which is equivalent to the original equation.
Therefore, the graph is symmetric with respect to the origin.
Hence, the graph of the equation x² + y - 36 = 0 is symmetric with respect to the y-axis and the origin, but not with respect to the x-axis.

Answers
An autonomous differential equation with equilibrium solutions at y=0 and y=3, and y' > 0 for 0 < y < 3 and y' < 0 for -inf < y < 0 and 3 < y < inf is dy/dx = 3y(1-y).
An autonomous differential equation is a type of ordinary differential equation that does not depend on any other variable but time. It has a single variable, usually denoted as y, and a single independent variable, usually denoted as t or x. An autonomous differential equation with equilibrium solutions at y=0 and y=3, and y' > 0 for 0 < y < 3 and y' < 0 for -inf < y < 0 and 3 < y < inf is dy/dx = 3y(1-y). This equation will have two equilibrium solutions at y=0 and y=3. The derivative of the equation, y’, is greater than 0 for 0 < y < 3, which means that the equation is increasing in this range. The derivative of the equation is less than 0 for -inf < y < 0 and 3 < y < inf, which means that the equation is decreasing in this range. This equation is a type of logistic equation and is often used to model population growth. It is also used to describe other phenomena such as the spread of an epidemic or the number of species in an ecosystem. Using the initial conditions y(0) = 2 and y(1) = 3, we can calculate the values of y at other time points using the equation dy/dx = 3y(1-y). At t=0.5, the value of y is y(0.5) = 2.5; at t=1.5, the value of y is y(1.5) = 2.875; and at t=2.5, the value of y is y(2.5) = 2.9375.
