Answer:
285 students were in school.
Step-by-step explanation:
5%=0.05
0.05*300=15
300-15=285
There were 285 students in school.
Given that 5% of the 300 students were absent, we can calculate it as follows:
= 5% of 300
= (5/100) x 300
= 0.05 x 300
= 15
Therefore, there were 15 students absent from school.
Now, the In school students
Total students - Absent students = In-school students
300 - 15 = 285
So, there were 285 students in school.

Which arithmetic sequence has a first term equal to 47 and a common difference of -18?
a.{-18, -65, -112, -159, …}
b.{47, 29, 11, -7, …}
c.{-18, 29, 76, 123, …}
d.{47, 65, 83, 101, …}
Answer:
b
Step-by-step explanation:
There are 2 sequences with a₁ = 47, b and d
The common difference of both is
(b)
d = a₂ - a1 = 29 - 47 = - 18
(d)
d = a₂ - a₁ = 65 - 47 = 18
The the sequence with first term 45 and common difference - 18 is b
The required sequence which has a first term equal to 47 and a common difference of -18 is {47, 29, 11, -7, …}. Option B is correct.
What is arithmetic progression?Arithmetic progression is the series of numbers that have common differences between adjacent values
What is geometric progression?Geometric progression is a sequence of series whose ratio with adjacent values remains the same.
Here,
An arithmetic sequence has a first term equal to 47 and a common difference of -18,
a = 47
d = -18
The sequence formed given as,
⇒ a, a + d, a + 2d, a + 3d
⇒ 47, 47 - 18, 47 + 2(-18), 47 + 3(-18)
⇒ 47 , 29, 11, -7 . . . . .
Thus, the above sequence matches the sequence given in option b.

has dimensions of 5000mm x 3600mm. How many plates can fit on this
table? What is the percentage they cover?
Please help me it’s 10 points also this is my first time on this app
Given :
Dimension of table :
5000 mm * 3600 mm
Area of rectangle = Length * width
Area of table = 5000 * 3600
Area of table = 18000000 mm²
Recall :
1 cm = 10 mm
Diameter of circular plate = 10cm
Converting to mm :
10 * 10 = 100 mm
Area = diameter/ 2 = 100 mm / 2 = 50 mm
Area of a circle = πr²
Area of circular plate = 3.14 * 50² = 7850 mm²
Number of plates = 18000000 / 7850
= 2292.9936 plates

a rectangle with a length of 9 inches and a width of 8 inches is divided in to squares of with sides of length 1 inch.One third of these squares are painted red , 1/8 of the remaining squares are painted green, and the others are left unpainted.How many squares are left unpainted?
Answer:
42
Step-by-step explanation:
rectangle = 8x9 = 72
1/3 0f 72 = 24 (72-24= 48)
1/8 of 48 =6 48-6 =42
red-----24
green-----6
unpainted-----42
24+6+42+=72
The 42 squares are left unpainted.
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
The area of rectangle = 8 x 9 = 72
One-third of these squares are painted red, 1/8 of the remaining squares are painted green, and the others are left unpainted.
1/3 of 72
1/3 x 72 = 24
(72-24= 48)
1/8 of 48
1/8 x 48 = 6
( 48-6 =42)
So,
red = 24
green = 6
unpainted = 42
The 42 squares are left unpainted.

69. A statistics instructor believes that fewer than 20% of Evergreen Valley College (EVC) students attended the opening midnight showing of the latest Harry Potter movie. She surveys 84 of her students and finds that 11 of them attended the midnight showing. The Type I error is to conclude that the percent of EVC students who attended is ________. a. at least 20%, when in fact, it is less than 20%. b. 20%, when in fact, it is 20%. c. less than 20%, when in fact, it is 20%. d. less than 20%, when in fact, it is less than 20%
Answer:
a. at least 20%, when in fact, it is less than 20%.
Step-by-step explanation:
Type 1 Error is to reject null hypothesis when it is actually true.
Here the null hypothesis is fewer than 20% of Evergreen Valley College (EVC) students attended the show.
In mathematics fewer than 20% means less than 20%.
So the null hypothesis is that less than 20 % students attended the show.
We have to reject this hypothesis .
We can reject this hypothesis when we assume that the % is greater than or equal to 20 %
At least 20% means greater than or equal to 20%.
So the best choice is option a.
at least 20%, when in fact, it is less than 20%.
