If ΔGJI and ΔPKH are similar, then ∡G≅∡P, ∡J≅∡K and ∡I≅∡H.
We have m∡G + m∡P = 50°, therefore m∡G = m∡P = 50° : 2 = 25°.
m∡I = 48° therefore m∡H = 48°.
We know, the sum of the measures of the angles of a triangle is equal 180°.
Therefore we have the equation:
m∡G + m∡J + m∡I = 180°
25° + m∡J + 48° =180°
73° + m∡J = 180° <em>subtract 73° from both sides</em>
m∡J = 107° → m∡K = 107°.
<h3>Answer: ΔGJI and ΔPKH: 25°, 107°, 48°</h3>
Answer:
D
Step-by-step explanation:
x -91
Answer:
<h2>-4</h2>
Step-by-step explanation:
Given the function f(x)=(x+4)², <u>the x intercept occurs at f(x) = 0,</u> substituting f(x) = 0 into the given equation to get the value of x we have;
Taking the square root of both sides
Subtracting 4 from both sides of the equation
Therefore the x intercept of the equation is -4
Answer:
1) Option C) Parameter
2) Option D) Statistic
Step-by-step explanation:
We are given the following statement n the question:
Phone-in poll conducted by a newspaper reported that 57% of those who called in liked ''real TV''.
The unknown true percentage of American citizens who like ''real TV'' is a parameter because here we talk about the whole population of Americans who like the real TV
- Parameters are numbers that summarize data for an entire population.
57% is the proportion of sample that is describing the sample of people who participated in the poll and liked real TV and thus, 57% is the statistic.
- A statistic is a characteristic of a sample. Generally, a statistic is used to estimate the value of a population parameter.
