Answer:
-45
Step-by-step explanation:
PEMDAS
First, parenthesis:
4 + 21 = 25
1 - 71 = 7
Then Subtraction:
25 - 70 = -45
Answer:
21.21%
Step-by-step explanation:
Assume that proportion of support follows normal distribution.For resulting in defeat the proportion of support should less than 0.5.Given that the proportion of support is p= 0.52.
Sample size(n)= 402
We know that standard deviation is given as

Now by putting the values

σ=0.0249
Proportion of support follows normal distribution with mean is 0.52 and standard deviation is 0.0249
We know that 
So

Z= -0.80
So P(Z<-.80) =0.2118 from standard table.
So the probability of news paper to predict defeat is 21.21%
Let the unknown angle be x.
That is
sin x = 4/5
cos x = 3/5
By drawing a right triangle in the first quadrant,
hypotenuse = 5
Adjacent side = 3
opposite side = 4
That is tan x = 4/3
From the calculator,
x = arctan(4/3) = 53 deg (nearest integer)
Answer: 53 deg. (nearest integer)
Answer:
N= -44/9 Hope this helped, <3
Step-by-step explanation:
Let's solve your equation step-by-step.
n−2=10n+42
Step 1: Subtract 10n from both sides.
n−2−10n=10n+42−10n
−9n−2=42
Step 2: Add 2 to both sides.
−9n−2+2=42+2
−9n=44
Step 3: Divide both sides by -9.
