Answer:
78.3% which would be a C+
Step-by-step explanation:
If the project was worth 20% of your grade and you got 50% on that project, we can multiply the decimal values of these percentages together to know exactly by how much your grade will drop.
0.2 * 0.5 = 0.1 or 10%
Now, we see that your grade will drop 10%. Meaning, that from your 87% you will actually have only 90% of that which is...
87 * 0.90 = 78.3
Therefore, your grade will go down to a 78.3% which would be a C+

if a, b, c, and d represent positive real numbers, what is the inequality when solved for x?
The inequality equation is x ≥ ( by - c - d ) / a
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
by - d ≤ ax + c be equation (1)
On simplifying the equation , we get
Subtracting c on both sides of the equation , we get
by - d - c ≤ ax
And , ax ≥ by - d - c
Divide by a on both sides of the equation , we get
x ≥ ( by - c - d ) / 2
Hence , the inequality is x ≥ ( by - c - d ) / a

A data set is Normally distributed with a mean of 25 and a standard deviation of 8. If you calculate the standard score of every observation in this data set, the resulting scores will have a distribution that has
Answer:
The answer is "A mean of 0 and a standard deviation of 1".
Step-by-step explanation:
The standard answer of its following formula is calculated by:

Its standard score relates to the sampling distribution with the normal distribution average standard variation of 0 and 1, correspondingly. The mean for a standard scoring is 0, and the normal deviation is 1. that's why the mean=0, standard deviation=1.

Cuál es el monto producido por S/ 80 000 durante 2 años 6 meses, si la tasa es de 16% anual compuesto trimestralmente? *
Answer:
118419,54
Step-by-step explanation:
Primero, convierta R como porcentaje en r como decimal
r = R / 100
r = 16/100
r = tasa de 0,16 por año,
Luego resuelve la ecuación para A
A = P (1 + r / n) ^ nt
A = Cantidad =?
P = Principal = 80000
R = 16%
n = Compuesto trimestralmente = 4
t = tiempo en años
= 2 años y 6 meses
12 meses = 1 año
6 meses = x
x = 6/12 = 0,5
t = 2.5 años
A = 80000,00 (1 + 0,16 / 4) (4) ^ (2,5)
A = 80000,00 (1 + 0,04)^ (10)
A = $ 118419,54

how to solve the median
Answer:
1.) Set the data set in the ascending order
2.) Start cancelling out numbers each side, like if u cancel out the first number, then cancel out the last as well.
3.) Keep doing the step 2 until u reach the middle most number.
4.) Sometimes there are 2 middle numbers left, in that case find their average (add both numbers together and divide the sum by 2) which would be ur middle most number.

1.) The check number on a check:
A.) identifies the bank and is located at the bottom left corner of the check.
B.) identifies the bank and is located at the top right corner of the check.
C.) identifies the transaction and is located at the bottom left corner of the check.
D.) identifies the transaction and is located at the top right corner of the check.
E.) None of these choices are correct.
Answer:
D) Identifies the transaction and is located at the top right corner of the check
Step-by-step explanation:
The check number on a check is the number located at the top right corner of the check, and it can also be found at the bottom of the check, located in lower right corner after the routing number and the account number
The check number aids in the tracking and identifying bank transactions such as to identify checks that the bank has processed and to know outstanding checks that are yet to be processed.
The check number also aids in balancing of the checkbook.
Therefore, the check number on a check identifies the transactions and is located at the top right corner of the check.

The perimeter of a parallelogram is 62cm. what is the length of the longest side if the equation of the sides are:-
*3x+5
*x+2
Given
perimeter is 62
Side 1 - 3x+5
Side 2 - x+2
Solution,
2(3x+5+x+2) = 62
4x+7 = 31
4X = 24
x = 6
Now substitute the value of x to get the sides
Side one - 3x+5 = 23cm
Side two - x+2 = 8cm
Answer- the length of the longest side is 23 cm

Given,
A pet store has 9 puppies.
includes 2 poodles, 5 terriers, and 2 retrievers.
Rebecka selects one puppy at random.
The probability of selection one pet from store is 1/9
After Rebecka selects one puppy at random pet store replaces the puppy with a puppy of the same breede. Now store has same number of pets.
Aaron chooses a puppy at random.
The probability of Aaron selecting a pet is 1/9.
As they both selects a poodle,
Rebecka : Probability of selection one poodle from store is 2/9
Aaron: Probability of selection one poodle from store is 2/9
The probability that both Rebecka and Aaron select poodles is 2/9 × 2/9 = 4/81
