Answer:
D)
Step-by-step explanation:
As if a statement is given which says that :Three less than the square of a number.
This means if the number is 'x'
Suppose the statement is : the value of y is 3 less than the square of x then the equation will be
By using two such statement that gives two equation we can find the value of x and y by solving one equation and putting it in the other equation which will give the values of two variables .
Answer: INDEPENDENT SAMPLES T-TEST
Step-by-step explanation:
Given that;
sample size n₁ = 40, sample size n₂ = 40
sample mean x₁ = 32.9, sample mean x₂ = 30.6
Standard deviation S₁ = 4.4, Standard deviation S₂ = 5.1
Now
NULL hypothesis H₀ : u₁ = u₂
and Alternative hypothesis H₁ : u₁ > u₂
Therefore based on the information provided above, the type of test that should be used to determine whether the level of nicotine are now lower than what they were 10 years ago is the INDEPENDENT SAMPLES T-TEST
The answer is a. 5 x 10³.
3.75 x 10^5 = 375,00.( population of Greenville)
375,000 ÷ 75 = 5,000 ( population of Fairview)
5 x 10³(1,000)= 5,000.
<span>Assume n begins with 1
an = 3n
a1 = 3*1 = 3
a2 = 3*2 = 6
a3 = 3*3 = 9
a4 = 3*4 = 12
Answer: 3,6,9,12</span>
Thus, the width of the poster is 8.185 inches and the length of the poster is 13.185 inches.
<h3>
What is Area of rectangle?</h3>
Area of rectangle is the region occupied by a rectangle within its four sides or boundaries. The area of a rectangle depends on its sides.
Area of poster = l X w
w · l = 72
x · x + 5 = 72
x . x = 72 - 5
x · x = 67
x² = 67
√x² = √67
Width x ≈ 8.185
so, by adding 5 inches, we get that
L = x + 5 = 8.185 + 5
length L = 13.185
Thus, the width of the poster is 8.185 inches and the length of the poster is 13.185 inches.
