Answer:
this will help u because my teacher just telled us about a statistical question
Step-by-step explanation:
The purpose of this task is to help students learn to distinguish between statistical questions and questions that are not statistical. A statistical question is one that can be answered by collecting data and where there will be variability in that data. This is different from a question that anticipates a deterministic answer.

The volume of a rectangular-based pyramid and a triangular-based pyramid with a congruent height and equal base areas are equal.
Plz help!!!
Answer:
False
Step-by-step explanation:
Rectangular pyramid formula: V=lwh/3
Triangular pyramid formula : V = a³ * √2 / 12
Therefore, since formulas are different, the base area will be different

John bought 27.5 m of cloth. How many centimetres of cloth did he buy ?
Answer:
2750
Step-by-step explanation:
It is 2750 because there is 100cm in 1m, which means if you do 27.5 times 100 you will then get the answer of 2750.
A certain bacteria population doubles in size every day. Suppose a sample starts with 1000 bacteria. The expression 1000 · 2x models the number of bacteria in the sample after x days. Evaluate the expression for x = 0, 2, 5.
Answer:
x=0, 0 bacteria
x=2, 4000 bacteria
x=5, 10000 bacteria
Step-by-step explanation:
For this question, all we have to do is input the x values into the expression in order to get the number of bacteria for each given x-days.
So for example if x=0 then we input it as 1000x2(0) which equals 0

Help with these questions, it’s Trigonometry Right Triangles
Answer:
(5). [tex]\theta=36.86^{\circ}[/tex] (6) H = 25 units
Step-by-step explanation:
Given that,
Height of triangle, H = 15
Base, B = 20
(5)
We need to find the value of tanA.
[tex]\tan A=\dfrac{P}{B}\\\\\tan A=\dfrac{15}{20}\\\\A=\tan^{-1}(\dfrac{15}{20})\\\\A=36.86^{\circ}[/tex]
(6)
For a right angled triangle, Pythagoras theorem will be applicable as follows :
[tex]H^2=B^2+h^2\\\\H^2=20^2+15^2\\\\H=\sqrt{20^{2}+15^{2}}\\\\H=25\ \text{units}[/tex]
Hence, this is the required solution.

Racer's average driving speed
for a 4-hour trip was 45 miles per
hour. During the first three hours he
drove 40 miles per hour. What was his
average speed for the last hour of his
trip?
A 70 miles per hour
B. 60 miles per hour
C. 50 miles per hour
D. 65 miles per hour
Answer:
the answer is C.
Step-by-step explanation:
(50+40)/2=45
Answer:
so to average 45mph for 4 hours, he had to drive 4x45 miles total
4x45= 180miles
now we know he drove 120 miles (3x40) in the first 3 hours.
so he drove 180-120= 60 miles in the last hour.
60mph

In a class of the students in a class are girls.
There are 28 boys.
What fraction of the class are boys?
How many students are in the class?
Answer:
[tex]Boys = 1 /4[/tex]
[tex]Total =112[/tex]
Step-by-step explanation:
Given
[tex]Girls= 3/4[/tex] --- missing information
[tex]Boys = 28[/tex]
Solving (a): The fraction that are boys
We have:
[tex]Girls= 3/4[/tex]
This implies that
[tex]Boys = 1 - Girls[/tex]
[tex]Boys = 1 - 3/4[/tex]
[tex]Boys = 1 /4[/tex]
Solving (b): Students in the class
If 1/4 are boys, then:
[tex]Boys = \frac{1}{4} * Total[/tex]
We also have that: [tex]Boys = 28[/tex]
So:
[tex]28= \frac{1}{4} * Total[/tex]
[tex]28 * 4 = Total[/tex]
[tex]112= Total[/tex]
[tex]Total =112[/tex]

Show work to find the value of x.
Answer:
Step-by-step explanation:
2x = x+30
subtract x on both sides
x = 30
As it is a isosceles triangle opposite sides are equal.
[tex]\\ \sf\longmapsto 2x=x+30[/tex]
[tex]\\ \sf\longmapsto 2x-x=30[/tex]
[tex]\\ \sf\longmapsto (2-1)x=30[/tex]
[tex]\\ \sf\longmapsto x=30[/tex]
Point Z is at a horizontal distance of 15 meters from the left- most point of the dam . What is the height of the dam at point Z?
Complete Question:
The profile of a dam is modeled by the equation y = 24 (StartFraction x Over 10 EndFraction) squared, where x represents horizontal distance and y represents height, both in meters.
Point Z is at a horizontal distance of 15 meters from the left-most point of the dam. What is the height of the dam at point Z?
Answer:
The height is 36 meters
Step-by-step explanation:
Given
[tex]y = 24 * \frac{x}{10}[/tex]
Required
The interpretation of the question is to determine the value of y when x = 15
Substitute 15 for x in: [tex]y = 24 * \frac{x}{10}[/tex]
[tex]y = 24 * \frac{15}{10}[/tex]
[tex]y = 24 * 1.5[/tex]
[tex]y = 36[/tex]
The height is 36 meters
