Find value of X in the given right triangle.
Answers
Answer:
44.4
Step-by-step explanation:
it is a right angled triangle so
with reference angle x
perpendicular (p) = 7
hypotenuse (h) = 10
so Now
sin x = p/h
sin x = 7 / 10
x = sin^-1( 7/ 10)
x = 44.42°
Rounding to nearest tenth
= 44.4°
Answer:
7.1
Step-by-step explanation:
you use the Pythagorean theorem to solve this problem. a^2+b^2=c^2.
you are finding value of b plug the variables in = 7^2+b^2=10^2
=49+b^2=100
subtract 49 from both sides
b^2=51
Square root of 51 =7.141 round to nearest tenth =7.1

Answers
a*2 + b = 26;
a*(-4) + b = -16;
then, a*6 = 42 => a = 7 => b = 26 -14 => b = 12;
from table, 7*9 + 12 = 63 + 12 = 75, correct;
7*(-8) + 12 = -56 + 12 = -44, correct;
slope = ( -44 + 16) / ( -8 + 4) = ( - 28) / (-4) = 7 = a;

Answer:
Therefore, Size of the sample space = 32
Step-by-step explanation:
Number of times a coin is tossed up = 5
Number of possible outcomes in a toss of a coin = 2 ( Head or a Tail)
The sample space can be calculated by calculating total number of possible outcomes in 5 tosses of the coin.
Number of outcomes in 1 toss of a coin = 2
Number of outcomes in 2 tosses of a coin = 2 × 2
Number of outcomes in 3 tosses of a coin = 2 × 2 × 2
Number of outcomes in 4 tosses of a coin = 2 × 2 × 2 × 2
Number of outcomes in 5 tosses of a coin = 2 × 2 × 2 × 2 × 2
⇒ Total number of outcomes = 32
Therefore, Size of the sample space = 32
the answer is 32.
