The most common IQ tests have a standardized mean of 100 and a standard deviation of 15. Based on this information, use the empirical rule to answer the following question: If approximately 348 prospective college students are tested for their IQ, approximately how many will fall within one standard deviation of the mean
Answer:
Step-by-step explanation:
Empirical Rule establishes that 68% of the population will fall in the interval μ₀ ± σ Then
348*0,68 = 237
237 students will be between ( 100-15 ; 100+15) That is
I = ( 85 ; 115 )

Which type of sequence does the situation represent?
A.
The situation represents an arithmetic sequence because the successive y-values have a common difference of 1.5.
B.
The situation represents an arithmetic sequence because the successive y-values have a common difference of 1.05.
C.
The situation represents a geometric sequence because the successive y-values have a common ratio of 1.5.
D.
The situation represents a geometric sequence because the successive y-values have a common ratio of 1.05.
The situation represents a geometric sequence because the successive y-values have a common ratio of 1.05.
What is geometric series?A geometric series is a series in which the division of any consecutive two terms will be the same.
here, we have,
to determine the situation:
The given parameters are:
Initial = 5200
Rate = 5%
Because the population by 5% every year, then the situation is a geometric sequence.
The common ratio is then calculated as:
Ratio = 1 + Rate
This gives
Ratio = 1 + 5%
Evaluate
Ratio = 1.05
Hence, the situation represents a geometric sequence because the successive y-values have a common ratio of 1.05.

who is right and wrong and why?
Answer:
BMX Ben is correct and Pizza Pete is wrong
Step-by-step explanation:
For Both equations, we must isolate the x, or move everything to one side. So you'd have to add 25 because you have a negative 25 and a negative number plus a positive version of itself equals 0
x-25=7
+25=25
__________
x=32
The second one is incorrect because you are subtracting negative 25 from a 25, which is -50

Answer:
none
Step-by-step explanation:
The equations describe curves that do not intersect. There are no real solutions.
_____
Additional comment
The system is consistent, not dependent, and of degree 2, so there will be two solutions. There are no real solutions, so the two solutions are complex: (-2i, 4-2i) and (2i, 4+2i).

What is the area of a triangle with a base of 7 mm and a height of 10 mm
Answer:
A≈3.5×10-5m²
Step-by-step explanation:
The requried area of the given triangle is 35-millimeter square.
What is the triangle?The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
What is an area of a triangle?The area of the triangle is given as half the product of the height and base of the given triangle.
Area of the triangle = 1/ 2 base × height
here,
in the given question, height = 10 mm and base = 7 mm
Area of the triangle = 1/ 2 10 × 7
Area of the triangle = 35 mm²
Thus, the requried area of the given triangle is 35-millimeter square.

3. Margo has drawn a parallelogram and is giving you clues about it for a guessing game. If her
first clue is that the parallelogram has 4 congruent sides but does not have congruent
diagonals, which parallelogram could Margo have drawn?
A Trapezoid
B. Rhombus
C Rectangle
D. Square
Answer:
B) Rhombus
Step-by-step explanation:
4 congruent sides is either a square or a rhombus
a square has congruent diagonals but a rhombus does not
The parallelogram is a Rhombus Margo has drawn.
What is a Parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure.
How to solve?
As we know,
The diagonal lengths of a square are of the same measure. The diagonal lengths of a rhombus are of different measures.
So, the figure will be a Rhombus.

Ethan sold 2/3 gallon of lemonade. Kayla sold some lemonade too. Together, they sold 1 1/4 gallons. Who sold more lemonade, Ethan or Kayla? How much more ?
Rewrite 1 1/4 as an improper fraction:
1 1/4 = 5/4 gallons.
Rewrite both fractions with a common denominator:
2/3 = 8/12
5/4 = 15/12
Subtract the amount Ethan sold from total:
15/12 - 8/12 = 7/12
Kayla sold 7/12
This means Ethan sold more, because 8/12 is more than 7/12

A photographer has enough liquid toner for sixty 4 in. by 8 in. prints. How many 11 in. by 14 in. prints will this amount cover?
(The toner covers the area of the print: Area=Length×Width)
The toner will cover ___ ( 13,11, 12, 48) prints of size 11 in. by 14 in.
Answer:
About 12 prints in 11×14
Step-by-step explanation:
The area of the 4×8 print is 32 in².
60 × 32= 1960
Divide by the area of an 11×14, 154 in²
1960/154 ≈ 12.47

Answer:
B.) I cant insert a 2x2 matric but the [5 7
7 4] matrix is correct
Step-by-step explanation:
I got a 5/5 on the test so I know that B is the correct answer
The matrix which represents (A-B)-C will be the matrix in option (B).
What is the matrix?matrix, a collection of numbers lined up in rows and columns to produce a rectangular array. The elements of the matrix, also known as the entry, are the numerals.
In another word, a matrix is a set of variables that are arranged in such a good way that we can create algebraic equation from that.
In computer graphics, where they have been used to describe picture transformations and other alterations, matrices have vital applications as well in many sectors.
Given that the matrix
A - B = [first raw 3 ,1 in second raw 2 ,0]
Now (A - B) - C = [ first raw 5 ,7 in second raw 7 , 4]
Hence, the correct option is (B).
