A truck is carrying 102 bushels of sweet potatoes, 101
bushels of tangerines, and 103 bushels of
summer squash. What is the total weight of the crops?
Answer:
306
Step-by-step explanation:
101+102+103=306
Answer:
71,400
Step-by-step explanation:
1) Given, the crops and their weight:
apples = 40 lbs
sweet potatoes = 60 lbs
tangerines = 40 lbs
summer squash = 65 lbs
2) The Truck is carrying:
10² bushels of sweet potatoes = 60 x 100 = 6,000 lbs
10¹ bushels of tangerines = 40 x 10 = 400 lbs
10³ bushels of summer squash = 65 x 1000 = 65,000 lbs
3) All together, the total weight of the crops are:
6,000 lbs + 400 lbs + 65,000 lbs = 71,400 lbs.
The total weight of the crops is 71,400 lbs.

These algebraic expressions are not equivalent. Explain why they are not equivalent
Answer:
Sample Answer:
Step-by-step explanation:
The coefficients on the x2 terms cancel each other because 1 – 1 = 0.
The constant was not included.
The coefficients on the x terms were subtracted incorrectly; 8x – 6x = 2x (not negative).
Answer:
Sample Response: If you simplify the first expression, you will not get the second expression. In the first expression, the x2 terms have coefficients of 1 and -1 and, when combined, the result is 0. Also, the x terms have coefficients of 8 and -6 and, when combined, the result is 2. Finally, the constant from the first expression is not in the second expression.

Step-by-step explanation:
What else would need to be congruent to show that ABC XYZ by ASA?
==========================================================
Explanation:
ASA stands for "angle side angle".
To use ASA, we must have two pairs of congruent angles, as well as a pair of congruent sides. The sides must be between the angles in question.
So far we're given
Angle Z = Angle CCB = ZYThe thing we're missing is the other pair of congruent angles. So the missing congruent pair of angles is Angle Y = Angle B as those two angles are adjacent to the segments mentioned above.
Something like angle A is not adjacent or touching segment CB. Also, angle X is not adjacent to segment ZY. So we can rule these angles out. We'd only use these angles if we were dealing with AAS instead of ASA.
Answer: C, Y, B
Step-by-step explanation:
Write an equation for the line in point slope form through the points (2, −6) and (−1, −8).
Let point A be [tex](2, -6)[/tex] and point B [tex](-1, -8)[/tex]
[tex]m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-8 - (-6)}{-1 - 2} = \frac{-8 + 6}{-1 -2} = \frac{-2}{-3} = \frac{2}{3}[/tex]
Use the point-slope formula and whichever point you want as , in this case I'll use
[tex]y - y_1 = m(x - x_1)\\y - (-6) = \frac{2}{3}(x - 2)\\y + 6 = \frac{2}{3}x - \frac{4}{3}\\y = \frac{2}{3}x - \frac{4}{3} - 6\\y = \frac{2}{3}x - \frac{14}{3}[/tex]

Information about the proportion of a sample that agrees with a certain statement is given below. Use StatKey or other technology to estimate the standard error from a bootstrap distribution generated from the sample. Then use the standard error to give a 95% confidence interval for the proportion of the population to agree with the statement. StatKey tip: Use "CI for Single Proportion" and then "Edit Data" to enter the sample information. Click here to access StatKey. In a random sample of 400 people, 112 agree and 288 disagree. Estimate the standard error using 1000 samples. Round your answer to three decimal places.
Answer:
a) Standard Error = 0.010
b) 95% Confidence Interval = (0.0924 , 0.1316)
Step-by-step explanation:
a) The formula for Standard Error = √Sample Proportion (1 - sample proportion)/n
Standard Error = √p (1 - p)/n
We are told in the question that:
In a random sample of 400 people, 112 agree and 288 disagree. Estimate the standard error using 1000 samples
p = x/n
n = 1000 because we were told to use it instead of 400
x = number for people that agree = 112
p = 112/1000
p = 0.112
Standard Error = √p (1 - p)/n
= √0.112 (1 - 0.112)/1000
= √0.112 × 0.888/1000
= √0.099456 /1000
= √0.000099456
= 0.0099727629
Approximately to 3 decimal places = 0.010
Therefore, the standard error is 0.010
b) The Question above also asked that we solve for the 95% Confidence Interval
The formula =
p ± z × Standard Error
p = 0.112
z score for 95% confidence interval = 1.96
Standard Error = 0.010
Confidence Interval =
0.112 ± 1.96 × 0.010
= 0.112 ± 0.0196
0.112 - 0.0196
= 0.0924
0.112 + 0.0196
0.1316
Therefore, the 95% confidence interval = (0.0924 , 0.1316)

What is the value of k in the equation?
20^k/ 20^4 = 20^9
Answer:
k = 13
Step-by-step explanation:
20 ^ k / 20^4 = 20^9
knowing the laws of exponents, diving two numbers of the same base with exponents is like subtracting the exponents, so
k^x / k^y
= k ^ (x - y)
apply that knowledge here
20 ^ k / 20 ^ 4 = 20 ^ 9
20 ^ ( k - 4 ) = 20 ^ 9
now the bases have no use here so ignore them, and just calculate the exponents
k - 4 = 9
solve using inverse operations
k - 4 = 9
+4 +4
k = 13
Answer:
k = 13
Step-by-step explanation:
20^k / 20^4 = 20^9
20^ k = 20^9 * 20^4
this is a math rule
a^n * a^m = a^(n+m)
this is because the denominators of a are the same
in this question , the bases are 20
in the case of multiplication when the bases are the same , we add the powers
hence we add the powers
= 9 + 4
= 13
hence k = 13

Step-by-step explanation:
The determinant of the coefficient matrix is equal to 2.
What is determinant of a matrix?The determinant of a matrix is the scalar value computed for a given square matrix. Linear algebra deals with the determinant, it is computed using the elements of a square matrix.
According to question,
3x - 2y +z = -4
-x + y - 2 = 2
2x -y + 2z = 2
[tex]\left[\begin{array}{ccc}3&-2&1\\-1&1&-1\\2&-1&2\end{array}\right][/tex]
Expanding the matrix,
3(2-1) + 2(-2+2) + 1(1-2)
=3+0-1
=3-1
=2.
Hence the determinant of the coefficient matrix = 2.
