Alex would have saved $1,000.02 over 3 months. The cost of purchases would have been less if he used his savings instead of a credit card because of no interest rates applied. Barry's loan is $120 less expensive than Alex's loan
Explanation:If Alex had saved $333.34 a month for 3 months, he would have saved $333.34 x 3 = $1,000.02. As for the cost of purchases using savings instead of a credit card, we can't directly answer that without knowing the associated credit card interest rate & the time duration. In general, using a credit card would have cost more due to the interest applied to the unpaid balance.
For the second part of your question related to loans, let's assume both Alex and Barry took out loans of $1,000 each for one year. Alex's loan, with an interest rate of 21%, would cost him $1000 x 21/100 = $210 in interest. Barry's loan, at an interest rate of 9%, would cost him $1000 x 9/100 = $90 in interest. Therefore, Barry's loan costs $210 - $90 = $120 less than Alex's loan.

Mali performed an experiment with a standard deck of 52 cards. She wanted to see if the face cards (Ace, King, Queen, and Jack) came up the expected number of times when she randomly selected 13 cards from the deck. A 3-column table with 4 rows. Column 1 is labeled Card with entries ace, king, queen, jack. Column 2 is labeled Theoretical (predicted frequency) with entries 1, 1, 1, 1. Column 3 is labeled Experimental (Observed frequency) with entries 0, 1, 1, 0. Mali noticed that the observed frequencies did not match the predicted frequencies. What does she need to change in her experiment to get closer to the predicted values based on the theoretical probability for all the face cards?
Answer:
Increase the number of trials...
Step-by-step explanation:
The number of experiment trials should be increased as to match the predicted frequencies.
What is Probability?Probability is the likeliness of an event to happen.
In probability experiments are performed to determine the probability of a required event.
Mali performed the experiments and found that the observed frequencies did not match the predicted frequencies.
To make the data closer to the predicted values, more number of trials to determine the frequencies should be done.

Rockin' Reggie's Music Shop sells about 200 guitar picks each week. Reggie orders picks by the gross (144) from a distributor. About how many gross should Reggie order for a three month supply.
Answer:
1872 gross should Reggie order for a three month supply.
Step-by-step explanation:
Given:
200 guitar picks each week.
To Find:
How many gross should be ordered for three months period
Solution:
Now the guitar picks corresponds to the order picks by gross as follows;
given that 200 guitar picks corresponds to 144 gross orders
Now 200 are sold for each weeks i.e 7 days
Now for 3 months there are approximately 13 weeks
so Total sell for 3 months=13*200=2600 guitars
Now The ratio of guitar picks to gross orders is ,
144/200
=1/1.39=0.72
So 2600 guitars corresponds to 2600*(1/1.39)
i.e. 2600/1.39
=1872 Gross orders are required to get three month of supply

One day, River writes down the numbers $1,$ $2,$ $\dots,$ $999.$ River chooses one of the digits written down at random. What is the probability that River chooses a $7$?
Answer:
100/963
Step-by-step explanation:
The number 1,2,3,...,999 is written down.
First, we determine the total number of digits written down
1-9 =9 digits 10-99= 2(99 - 10 + 1) =2(90) digits100-999=3(999 - 100 + 1) =3(900) digitsTotal Number of digits=9+2(90)+3(900) =2889
Number of Digit 7 between 1 and 999
In the Units’ place, 7 occurs once every decade (7, 017… 997)=10 X 10= 100 times In the Tens place, 7 occurs in the ten times every century (70–79, 170–179, …, 970–979) =10 X 10= 100 times In the hundreds’ place, 7 occurs once in the hundreds’ place (700, 701, …, 799) = 100 timesTherefore, the number 7 will be found a total of 300 times between 1 and 999.
Therefore, the probability of selecting a "7" = 300/2889
= 100/963
Final answer:
The probability that River chooses a 7 from the numbers 1 to 999 when randomly selecting a digit is approximately 0.111 or 11.1%. This is calculated by dividing the total occurrences of the digit 7 (321 times) by the total number of digits written (2889 digits).
Explanation:
To calculate the probability that River chooses a 7 from the numbers 1 to 999 when randomly selecting a digit, we must first determine the total number of times the digit 7 appears in this range. In numbers 1-9, 7 appears once; in numbers 10-99, it appears 10 times in the units place plus 10 times in the tens place; and in numbers 100-999, it appears 100 times in the units place, 100 times in the tens place, and 100 times in the hundreds place. Therefore, there are a total of 1 + 10 + 10 + 100 + 100 + 100 = 321 occurrences of the digit 7.
Next, we calculate the total number of digits written down from 1 to 999. For numbers 1-9, there are 9 digits. For 10-99, there are 90 numbers times 2 digits each, totaling 180 digits. For 100-999, there are 900 numbers times 3 digits each, totaling 2700 digits. The sum of all digits is 9 + 180 + 2700 = 2889 digits.
The probability that River chooses a 7 is the number of 7s divided by the total number of digits, which is 321/2889. Simplifying this fraction, we get a probability of approximately 0.111 or 11.1%.

You are going to use an incline plane to lift a heavy object to the top of a shelving unit with a height of 6 ft. The base of the incline plane is 10 ft from the shelving unit. What is the length of the incline plane?
To determine the length of an inclined plane given the height (6 ft) and base (10 ft), use the Pythagorean theorem, which reveals that the length of the inclined plane is approximately 11.66 feet.
Explanation:The student is asking about the length of an inclined plane when given the height and the base of the incline. To find the length of the inclined plane, we can use the Pythagorean theorem because the height, base, and the length of the incline form a right triangle.
The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, the hypotenuse is the length of the incline, the vertical side is the height of the shelving unit (6 ft), and the horizontal side is the base of the incline (10 ft).
The formula is: length of the incline2 = height2 + base2. Plugging in the numbers, we get: length of the incline2 = 62 + 102, which simplifies to length of the incline2 = 36 + 100. The square root of 136 gives us the length of the incline, which is approximately 11.66 feet.

Rewrite the function by completing the square h(x) =4x^2+4x+1
Answer:
4(x + [tex]\frac{1}{2}[/tex] )²
Step-by-step explanation:
Given
h(x) = 4x² + 4x + 1
To complete the square the coefficient of the x² term must be 1
Factor out 4 from 4x² + 4x
h(x) = 4(x² + x) + 1
add/subtract ( half the coefficient of the x- term )² to x² + x
h(x) = 4(x² + 2([tex]\frac{1}{2}[/tex] )x + [tex]\frac{1}{4}[/tex] - [tex]\frac{1}{4}[/tex] ) + 1
= 4(x + [tex]\frac{1}{2}[/tex] )² - 1 + 1

True or False: If your expression contains more than one set of parentheses, you should evaluate all of them
before doing anything else.
B
False
Answer:
You should evaluate whatever is in the parenthesis first.
By standardization of algebra, we can say that the statement is true, you should evaluate the parentheses at the beginning.
In general problems, we usually use parentheses to separate larger problems in smaller ones. The benefit of doing this is that we can tackle these smaller problems one by one instead of a larger problem all at once.
Whit this in mind, when an expression has several sets of parentheses, the first thing that you need to do is simplify them by evaluating them, so yes, the statement is correct.
