Answer:
2. a. - 1b.[tex] - \frac{2}{3} [/tex]3. a. 4b. 6Step-by-step explanation:
[tex]2. \: a. \: \sqrt[3]{ - 1} [/tex]
[tex] = \sqrt[3]{( - 1 )\times ( - 1 )\times( - 1)} [/tex]
= -1 (Ans)
[tex]b. \: \sqrt[3]{ - \frac{8}{27} } [/tex]
Since,
[tex] \sqrt[3]{ - x} = - \sqrt[3]{x} [/tex]
Hence,
[tex] = - \sqrt[3]{ \frac{8}{27} } [/tex]
[tex] = - \sqrt[3]{ \frac{2 \times 2 \times 2}{3 \times 3 \times 3} } [/tex]
[tex] = - \frac{2}{3} (ans)[/tex]
[tex]3. \: a. \: 10 - 2 \sqrt{9} [/tex]
[tex] = 10 - 2 \sqrt{3 \times 3} [/tex]
= 10 - 2 × 3
= 10 - 6
= 4 (Ans)
[tex]b. \: 70 - {( \sqrt[3]{64} )}^{3} [/tex]
[tex] = 70 - \sqrt[3]{ {64}^{3} } [/tex]
[tex] = 70 - \sqrt[3]{64 \times 64 \times 64} [/tex]
= 70 - 64
= 6 (Ans)

In the morning, the number of ducks at the reservoir was 80. By noon, the reservoir had 135 ducks. What was the percent of change in the number of ducks? Round your answer to the nearest whole percent.
Answer:
60 percent
Step-by-step explanation:
number of ducks in morning=80
ducks in after noon=135
for percentage
80/135=0.5925=0.60
0.60*100=60 percent

Jeans cost $38. The tax is 8% what is the total cost?
Reporting if wrong, please explain.’
Answer:
$41.04
Step-by-step explanation:
8% = 0.08
38(0.08) = 3.04
$3.04 is the tax for the jeans. Now we just have to add it to the price.
38 + 3.04 = $41.04
Answer:
$41.04
Step-by-step explanation:
0.08 (the tax converted from percentage) x 38 (initial cost) = 3.04(tax amount)
38(initial amount) + tax amount (3.04) = 41.04
the cost after tax is $41.04
understand now? To convert 8% to a decimal just move the decimal to the left twice (because we’re representing out of 100%)

Step-by-step explanation:
The outcome of the first event does affect the outcome of the second, so that the probability is changed
Answer:
Dependent Events
Step-by-step explanation:
Suppose we have 3 balls 1,2,3 and we have to find the probability of choosing one ball.
If the first ball is chosen the probability will 1/3 leaving behind 2 balls in the bag. If the first ball is not replaced and we have to choose again the probability of choosing the second or third ball would be 1/2 which is changed from the original probability of choosing 1 ball out of 3. In this the outcome of the first event does affect the outcome of the second, so that the probability is changed. This is when choosing is done without replacement.
In this the events are called dependent events.
Consider this scenario again and suppose we replace the first ball after it is chosen back into the bag. Then again we choose another ball . And the probability of choosing the second ball after replacement remains the same as choosing the first ball. In this he outcome of the first event does not affect the outcome of the second, so that the probability remain the same. This is done by replacement.In this the events are independent.

Emi computes the mean and variance for the population data set 87, 46, 90, 78, and 89. She finds the mean is 78. Her steps for finding the variance are shown below.
What is the first error she made in computing the variance?
A.) Emi failed to find the difference of 89 - 78 correctly.
B.) Emi divided by N - 1 instead of N.
C.) Emi evaluated (46 - 78)2 as -(32)2.
D.) Emi forgot to take the square root of -135.6.
Answer: Choice C) Emi evaluated (46-78)^2 as -(32)^2
Explanation:
The "46-78" is inside the parenthesis, so the result must also stay in the parenthesis. This means (46-78)^2 would become (-32)^2. The negative must be inside the parenthesis as well. Squaring the "-32" leads to a positive result, so every item being added is positive after the squaring operations are applied.
find the volume of the composite figure
lets do this step by step.
First: we need to break this into to prisms.
Next lets say the dimensions:
4 x 2 x 1 and 2 x 2 x 1
now we multiply them and then add them
8 + 4 = 12
volume = 12 cubic units.

Find the missing factor
2x ^ 2 + 5x - 3 = (2x - 1)
Answer:
(x-3)
Step-by-step explanation:
2x²+5x-3=x² +x−6x−3 =x(2x+1)-3(2x+1) =(2x+1)(x-3)
The required missing factor is (x - 3).
Given the equation, 2[tex]x^2[/tex] + 5x - 3 = (2x - 1).
To find the missing factor in the equation 2x^2 + 5x - 3 = (2x - 1), to factorize the quadratic equation on the left side and compare it to the given factor (2x - 1).
The factors will have the form (ax + b)(cx + d), where a, b, c, and d are constants.
To find values for a, b, c, and d such that (ax + b)(cx + d) is equal to
2[tex]x^2[/tex] + 5x - 3.
To determine the values of a, b, c, and d, we can use the FOIL method (First, Outer, Inner, Last). FOIL involves multiplying the first terms, the outer terms, the inner terms, and the last terms of the two binomials.
Factorize the quadratic equation:
2[tex]x^2[/tex] + 5x - 3
(2x - 1)(cx + d) = 2[tex]x^2[/tex] + 5x - 3
Expanding the left side using FOIL:
(2x - 1)(cx + d) = 2[tex]x^2[/tex] + 6x - x - 3
Combining like terms on the right side:
(2x - 1)(cx + d) = 2x( x - 3) -1 (x - 3)
Combining like terms on the right side:
(2x - 1)(cx + d) = (2x - 1)(x - 3)
By comparing the coefficients of the terms on both sides of the equation, determine the missing factor. Observe that the coefficient of x^2 is 2 on both sides, and the coefficient of x is -1 on both sides.
Therefore, the missing factor is (x - 3).
Hence, the complete factorization of the quadratic equation
2[tex]x^2[/tex] + 5x - 3 = (2x - 1)(x - 3).

Kevin and Clark each bought a new book for $50. Kevin sold his book to the used bookstore for 25% less than the original price. Clark sold her book to the used bookstore for 40% less than the original price. How much more money, in dollars, did Kevin receive for his book than Clark received for her book?
Answer:
i think kevin made $7.50 more than clark
Step-by-step explanation:
25% of 50 is 12.5. 50-12.5= 37.5
40% of 50 is 20. 50-20=30
