It can be deduced that the null hypothesis is H: p = 0.25 and the alternative hypothesis is H: p > 0.25.
What is the null hypothesis?It should be noted that null and alternate hypothesis are written based on the population parameter.
From the information given, the claim is that they card was identified significantly more than chance would suggest. The proportion of card selected will be:
= 1/4 = 0.25
Therefore, the null hypothesis is H: p = 0.25 and the alternative hypothesis is H : p > 0.25.

Help me with this please!!
Answer:
35 m²
Step-by-step explanation:
Given:
length of each side of the square compost heap = 1.2 mratio of compost heap side length to hedge length = 2 : 11⇒ length of hedge = (1.2 ÷ 2) x 11 = 6.6 m
Given:
length of gate = 2mlength of gate is 1/4 length of pond⇒ length of pond = 2 x 4 = 8m
Given:
area of pond = 28 m²length of pond = 8 m (from previous calculation)⇒ width of pond = 28 ÷ 8 = 3.5 m
⇒ perimeter of pond = 2 x 8 + 2 x 3.5 = 23 m
Given:
length of pond = 8 mlength of gate = 2 m⇒ length of flowerbed = 8 + 2 = 10 m
Given:
length of flowerbed = 10 mperimeter of flowerbed = perimeter of pong = 23 m⇒ width of flowerbed = [23 - (2 x 10) ] ÷ 2 = 1.5 m
Area of grass = (length of gate x width of pond) + (length of flowerbed x [length of hedge + length of compost heap - width of flowerbed - width of pond])
= (2 x 3.5) + (10 x [6.6 + 1.2 - 1.5 - 3.5])
= 7 + (10 x 2.8)
= 35 m²

A statistics student considered many methods for collecting data from adults to estimate support for lowering the voting age to 16 years old. Which of the following methods would be least likely to include sampling bias?
A) A random sample of 500 adults in the state
B) A random sample of 200 students at a large high school
C) A survey of people leaving the local mall on the weekend
D) An online survey where adults are invited to share their opinions
The sampling method which is least likely to include sampling bias is: A. A random sample of 500 adults in the state.
What is sampling bias?A sampling bias can be defined as a type of bias in which members of an intended population are selected in such a way that some members have a higher or lower sampling probability than the other members.
This ultimately implies that, a sampling bias occur when members of an intended population are selected incorrectly and as such resulting in a sample that is not representative of the entire population.
In conclusion, a random sample of 500 adults in the state is least likely to include sampling bias.

Here we have some problems about circles, the solutions are:
a) 490.6 yd^2b) x = 15c) x = 27How to find the area of a circle?
We know that for a circle of diameter D, the area is given by:
A = pi*(D/2)^2
where pi = 3.14
In the image we can see that the diameter of the circle is 25 yd, replacing that in the area equation we get:
A = 3.14*(25yd/2)^2 = 490.6 yd^2
How to find the value of x?For the second image, each line creates two 180° angles. So, if we look at the tilted line, we can see that it is divided in two angles, one of 37° and the other that depends of x, so we can write:
180° = 37° + (9x + 8)°
180° - 37° - 8° = (9x)°
135°/9° = x = 15
So the value of x is 15.
For the last image:
Notice that we have a 90° angle denoted, then the other 3 sections must add up to 270°.
270° = 54° + (2x + 21)° + (5x + 6)°
Now we solve this for x:
270 - 54 - 21 - 6 = 2x + 5x
189 = 7x
189/7 = x = 27
x is equal to 27

What is an equation of the line in slope intercept form?
a. y = 2x - 2
b. y = -2x - 2
c. y = -2x + 2
d. y = 2x + 2
Answer:
○ [tex]\displaystyle y = 2x + 2[/tex]
Step-by-step explanation:
Starting from the y-intercept of [tex]\displaystyle [0, 2],[/tex]travel south two units, then west one unit to the endpoint AND x-intercept of [tex]\displaystyle [-1, 0].[/tex]Doing so will give you the rate of change of 2:
[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m \\ \\ \frac{-2 ± 0}{0 - 1} = m \hookrightarrow \frac{-2}{-1} = m \\ \\ 2 = m[/tex]
With all the above information, you arrive at the equation of the line.
