180-60=120
60 is from the complementary angle

It’s 120 because exterior angle is equal to a + b in this case that’s 50 and 70 so 50 + 70 =120

If ƒ(x) = -5n + 1 and g(x) = -6n + 2, find (ƒ + g)(-2).

Stels [109]

(f+g) (n) = (–5n +1 ) + (- 6n +2) = –11n +3

(f+g) (n) = –11n +3

(f+g) (–2) = – 11 (–2) +3 = 22 +3 = 25

I hope I helped you^_^

Answer:

Step-by-step explanation:

We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean

For the null hypothesis,

µ = 12

For the alternative hypothesis,

µ < 12

Since the population standard deviation is given, z score would be determined from the normal distribution table. The formula is

z = (x - µ)/(σ/√n)

Where

x = sample mean

µ = population mean

σ = population standard deviation

n = number of samples

From the information given,

µ = 12 minutes

x = 8 minutes

σ = 12 minutes

n = 36

z = (8 - 12)/(12/√36) = - 4/2 = - 2

Test statistic = - 2

How to solve these equations?

Scorpion4ik [409]

1) / sin x / = y ≥ 0 ;
We solve the equation $y^{2} +y - 2 = 0 ;
$
a = 1 ; b = 1 ; c = - 2 ;
$b^{2} - 4ac = 9 ;$
y1 = ( - 1 + 3 ) / 2 = 1 ≥ 0 ( correct ) ;
y2 = ( - 1 - 3 ) / 2 = - 2 ≥ 0 ( false ) ;
Then, / sin x / = 1 ;
sinx = + 1 or sin x = - 1 ;
x ∈ { 90 } U { 270 } ;
x ∈ {90 , 270}.
