A bag hes 10 red marbles, 3 green marbles,
7 yelow marbles, and 5 blue merbles. What is
the probability of crowing a red marble and
then g, blue, marble without replacing the first?
Answer:
[tex]\frac{3}{5}[/tex]
Step-by-step explanation:
Probability is the chance of an event happening. One finds the probability of an event by using the following general formula,
[tex]\frac{desired}{total}[/tex]
In this case, the desired outcome is pulling whether a red or blue marble from the bag, the desired equals the sum of the number of red and blue marbles.
(red) + (blue)
= 10 + 5
= 15
The total number of marbles is the sum of all the number of marbles in the bag.
(red) + green) + (yellow) + (blue)
= 10 + 3 + 7 + 5
= 25
Now substitute these values into the formula to find the probability, then simplify,
[tex]\frac{15}{25}[/tex]
Divide both the numerator and denominator by (5),
[tex]\frac{3}{5}[/tex]
Listed below are amounts of arsenic in samples of brown rice from three different states. The amounts are in micrograms of arsenic and all samples have the same serving size. The data are from the Food and Drug Administration. Use a 0.05 significance level to test the claim that the three samples are from populations with the same mean. Assume that the distributions for each state are normal and that all variances are equal.

Answer:
Texas Texas Texas is I think right
No, the claim that the three samples are from populations with the same mean is not correct and this can be determined by using the given data.
Given :
The amounts are in micrograms of arsenic and all samples have the same serving size. The data are from the Food and Drug Administration. Use a 0.05 significance level.The Hypothesis test is given below:
Null Hypothesis: [tex]H_0:\mu_1=\mu_2=\mu_3[/tex]
Alternative Hypothesis: [tex]H_a:\mu_1\neq \mu_2\neq \mu_3[/tex]
For the F-test, the test statistics is given by:
[tex]F = \dfrac{MS_{\rm{between}}}{MS_{\rm{within}}}[/tex]
Now, substitute the values of known terms in the above expression.
[tex]F = \dfrac{15.8252}{0.6896}[/tex]
[tex]F = 22.95[/tex]
So, the p-value regarding the value of F is:
[tex]P-value=P(F>22.95)[/tex]
[tex]P-value = 1.0.9999[/tex]
[tex]P-value = 0.0001[/tex]
The Null Hypothesis is rejected because P-value is less than the significance value.

B Reading Choose the best estimate for the multiplication problem below. 85 x 86
A. 8100
B. 10,400
C. 12,200
Answer:
A. 8100
Step-by-step explanation:
85 x 86
To estimate, we multiply 85*100, which is the easiest multiplication, as a multiplication by 100 is the same as placing two zeros at the end of the number.
85*100 = 8500
Since 86 < 100, 85*86 < 8500. Thus, the correct estimate is given by option A.

Terry finished cooking at 7:36 p.m. She cooked for 2 hours and 40 minutes. What time did she start cooking?
Answer:
2:56 pm
Step-by-step explanation:
end time: 7:36 pm
Borrow one hour from the hours and add it as 60 minutes to the minutes.
7:36 pm = 6:96 pm
Now subtract 2:40 from 6:96.
Subtract 2 from 7 and subtract 40 from 96.
7:36 pm - 2:40 = 6:96 pm - 2:40 = 2:56 pm
Answer: 2:56 pm
Sum of 4x^3+6x^2+2x^2-3 and 3x^3+3x^2-5x-5 is
9514 1404 393
Answer:
7x^3 +11x^2 -5x -8
Step-by-step explanation:
Combine like terms.
(4x^3+6x^2+2x^2-3) + (3x^3+3x^2-5x-5)
= (4 +3)x^3 +(6 +2 +3)x^2 +(-5)x + (-3 -5)
= 7x^3 +11x^2 -5x -8
_____
Noting that the first expression contains two x^2 terms, we wonder if you actually want the sum ...
(4x^3+6x^2+2x-3) + (3x^3+3x^2-5x-5)
= (4 +3)x^3 +(6 +3)x^2 +(2 -5)x +(-3 -5)
= 7x^3 +9x^2 -3x -8

If I had 36 apples what is the percentage of 20
Answer:
20 apples is 55.55% of 36 apples.
Step-by-step explanation:
Given that I had 36 apples, to determine what is the percentage of 20 of them, the following calculation must be performed:
36 = 100
20 = X
(20 x 100) / 36 = X
2000/36 = X
55.55 = X
Therefore, 20 apples is 55.55% of 36 apples.
What is the measure, in degrees, of angle b?
The top angle is the same as the bottom angle, since they are vertically opposite angles.
b+20=40
b=40-20
b=20
It is also 20 degrees.
Answer:
Step-by-step explanation:
angle b+20 degree=40 degree(being vertically oppoite angles)
angle b=40-20
angle b=20
therefore angle b=20 degree.

What is the range of possible sizes for side x?
Answer:
x = 3.96
Step-by-step explanation:
To find the missing side length you'll need the formula a^2 + b^2 = c^2
a and b would be the shorter ends, 2.8 and 2.8
c would be the longer end that's opposite the right angle.
so substitute values
2.8^2 + 2.8^2 = c^2
7.84 + 7.84 = c^2
15.68 = c^2
√15.68 = √c^2
3.959797 = c
c = 3.96
side c would be side x so x is 3.96

Chau rented a truck for one day. There was a base fee of $18.95, and there was an additional charge of 95 cents for each mile driven. Chau had to pay $198.50
when he returned the truck. For how many miles did he drive the truck?
Let's say John drove 2 miles. He had to pay the base fee of $18.99 and $.75(2) = $1.50, so he paid $20.49 total.
We are given his total, though, and asked to find the mileage.
18.99 + .75m = 199.74
-18.99 -18.99
.75m = 180.75
.75 .75
m = 241
So, John drove 241 miles.

Suppose that you are interested in the relationship between the return rate on a stock in 2010 compared to the return rate in 2009.-You believe that the return rates in both years are positively correlated. A sample of 15 stocks'yields the following regression results: b0=5.3, b1= 1.04, sb= 1.79, and MSE = 35.4. 1:79, sb= 0.2163, R2 = 0.64
i. How would you explain the slope coefficient b1?
ii. What is the least squares regression line?
iii. What is the predicted value of y when x = 5
iv. Calculate the error sum of squares.
v. Calculate the total sum of squares.
vi. Calculate the regression sum of squares.
vii. Prepare the analysis of variance table for regression.
Step-by-step explanation:
1. we have b1 = 1.04 which is positive. we say that the return I. 2009 is positively correlated with the return in 2010.
2. Y = b0 + b1X
Y = 5.3 + 1.04X
3. If x = 5
Y = 5.3 + 1.04(5)
Y = 10.5
4. SSE = mse x (n-2)
n = 15, mse = 35.4
SSE = 35.4 x(15-2)
= 35.4 x 13
= 460.2
5. We are to find SST here
R² = SSR/ SSR + SSE
R² = 0.64
SSE = 460.2
0.64 = SSR/SSR+460.2
Cross multiply
0.64(SSR + 460.2) = SSR
0.64ssr + 294.528 = SSR
Collect like terms
294.528 = SSR - 0.64SSR
294.528 = 0.36SSR
SSR = 294.528/0.36
SSR = 818.13
SST = SSR + SSE
= 818.13 + 460.2
= 1276.53
6. The SSR has been calculated to be 818.13
