Given that A = {1, 2, 3, 4, 5, 6] maps respectively to B = {3, 4, 5, 6, 7, 8). Find an injective function f(x) such that f: A →

Answer: f(x) = x + 2
Step-by-step explanation:
A = {1, 2, 3, 4, 5, 6]
B = {3, 4, 5, 6, 7, 8)
for each A, B is 2 more
f(1) = 1 + 2 = 3
f(2) = 2 + 2 = 4
f(3) = 3 + 2 = 5
and so on...
⇒ f(x) = x + 2
Answer: 30°
explanation:
4x + 2x = 180°
6x = 180°
x = 180/6
x = 30°
hope this helps :)
Answer:
The value of test statistic
|Z| = |-2.2883| = 2.2883
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the mean of the Population = 57.7miles/gallon
The standard deviation of the Population = 1.9
The mean of sample x⁻ = 57.4
Given that the sample size 'n' =210
level of significance = 0.1
<u><em>Step(ii):-</em></u>
Test statistic
Z = -2.2883
|Z| = |-2.2883| = 2.2883
<u><em>Final answer:-</em></u>
The value of test statistic
|Z| = 2.2883
Answer:
1) m<2 = 115°
2) m<5 = 83°
3) m<8 = 45°
4) m<4 = 137°
Step-by-step explanation:
When two lines cross over each other, creating four angles, the opposite angles are equal.
So in question one, <1 is equal to <2, the angle opposite it, and so it is 115°.
Similarly, in question two, <5 = <6 = 84°.
In question three, <8 = <9 = 45°.
and in question four, <3 = <4 =137°.
