Simplify the following expression.

5^-5/2 x 5^9/2

A.

B.

C.

D.

Answer:

Yes

Step-by-step explanation:

I'm not good with explanations but, $1 = 4 quarters, so Emil and Jade

subtracted $1 from each pile and then added $1 to each pile.

Since they subtracted and added the same amounts to each

pile, the piles are equal in value.

Yes, both of them will have the same amount after exchanging the money.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Emil has $1 and a quarter. Jade has 5 quarters. If Emil gives Jade $1 and Jade gives Emil 4 quarters.

The amount can be balanced as below,

$1 = 4 quarters

E + 4 Quarters  = J + $1

E + $1 = J + $1

Hence, both will have the same amount.

Hello.

First of all, let the number be t.

The product of 5 and t is written like so:

[tex]\mathrm{5t}[/tex]

9 increased by means we add 9, so let's add 9 to 5t:

5t+9

Now, this expression is greater than or equal to -18:

[tex]\mathrm{5t+9\geq -18}[/tex]

Therefore, the final answer is:

[tex]\mathrm{5t+9\geq -18}[/tex]

I hope it helps.

Have a nice day.

Considering that for each item, there are only two possible outcomes, and the probability of an item being defective is independent of any other item, the binomial distribution is appropriate.

It is the probability of exactly x successes on n repeated trials, with p probability of a success on each trial.

Answer:  There are eight steps and two methods. I will be showing you one of them. If you're wondering, I am in 7th grade. I go to K12 online school.

Step-by-step Explanation: 1. Add together the lengths of the bases. The bases are the 2 sides of the trapezoid that are parallel with one another. If you aren’t given the values for the base lengths, then use a ruler to measure each one. Add the 2 lengths together so you have 1 value.[1]

For example, if you find that the top base (b1) is 8 cm and the bottom base (b2) is 13 cm, the total length of the bases is 21 (8 cm + 13 cm = 21 cm, which reflects the "b = b1 + b2" part of the equation).
2. Measure the height of the trapezoid. The height of the trapezoid is the distance between the parallel bases. Draw a line between the bases, and use a ruler or other measuring device to find the distance. Write the height down so you don’t forget it later in your calculation.[2]

The length of the angled sides, or the legs of the trapezoid, is not the same as the height. The leg length is only the same as the height of the leg is perpendicular to the bases.

3. Multiply the total base length and height together. Take the sum of the base lengths you found (b) and the height (h) and multiply them together. Write the product in the appropriate square units for your problem.[3]

In this example, 21 cm x 7 cm = 147 cm2 which reflects the "(b)h" part of the equation.

4. Multiply the product by ½ to find the area of the trapezoid. You can either multiply the product by ½ or divide the product by 2 to get the final area of the trapezoid since the result will be the same. Make sure you label your final answer in square units.[4]

For this example, 147 cm2 / 2 = 73.5 cm2, which is the area (A).

QUESTION 31

Step-by-step explanation:

3x+5=2x-1

Subtract 5 from both sides

3x+5-5=2x-1-5

Simplify

3x=2x-6

Subtract 2x from both sides

3x-2x=2x-6-2x

QUESTION 32

1/3(6x+12) = 1/2(4x-8) + 8

1/2(4x-8) = 4x-8/2 +8

1/3(6x+12) = 4x-8/2 +8

2(6x+12) = 12(x-2) + 48

12x+24

12x+24 = 12x+24

12x+24 - 24 = 12x+24 - 24

Answer:

Yes, they are similar according to Angle Side Angle postulate.

Step-by-step explanation:

Step-by-step explanation:

you must have misunderstood. a mile is much longer than a kilometer.

so, the relation is correctly (but still only roughly)

8 kilometers = 5 miles

100 km = 8×x km

x = 100/8 = 25/2 = 12.5

now, we need to apply the same factor to 5 miles

5×12.5 miles = 62.5 miles per hour

so, 100 km/h = 62.5 miles/h

now, if the relation would truly be

8 miles = 5 kilometers

then

100 km = 5×x km

x = 100/5 = 20

now we apply the same factor to the miles and get

8×20 miles = 160 miles

and 100 km/h = 160 miles/h

but it is not.

these would be the correct numbers, if we asked what a speed limit of 100 miles per hour would be in kilometers per hour.

and yes,

100 miles/h = 160 km/h

Using Venn probabilities, it is found that the probability that he receives an offer on at least one of the jobs is given by:

D. 0.80

In a Venn probability, two non-independent events are related with each other, as are their probabilities.

The "or probability" is given by:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

In this problem, we have that:

Then, the probability of getting an offer on at least one job is:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.5 + 0.6 - 0.3 = 0.8[/tex]

Hence option D is correct.
