Answer:
90 + 29 + x = 180
119 + x = 180
-119 -119
X = 61 degrees
A triangle will always equal 180 degrees.
Given that there is a right triangle it is 90 degrees, also given that 29 degrees is there we add those and add x (the unknown degree) to equal 180 degrees.
Answer:
Parameter = 0.5
Null hypothesis : H0 : P0 = 0.5
Alternative hypothesis ; H0 : P0 > 0.5
Pvalue = 0.99966
Step-by-step explanation:
The parameter defines a statistical value or calculation which is derived from the population.
The parameter in this scenario is the population proportion, P0 which is 0.5
The scenario above describes a scenario to test the difference in population.
The null hypothesis, that bride and groom are of the same age ;
H0 : P0 = 0.5
The alternative hypothesis ; the bride is younger Than the groom in more than half of the population.
H1 : p0 > 0.5
To obtain the Pvalue :
Test statistic : (phat - P0) ÷ √(p0(1 -p0) / n)
Phat = x/n
x = 67 ; sample size, n = 100
Phat = x / n = 67/100 = 0.67
P0 = 1 - 0.5 = 0.5
Tstatistic = (0.67-0.50) ÷ √(0.5(0.5) / 100)
Tstatiatic = 0.17 ÷ 0.05
Tstatistic = 3.4
P-value : p(Z < 3.4) = 0.99966 (Z probability calculator).
A(1) = - 3 ;
a(2) = a(1) + ( 2 - 1 )d ;
3 = -3 + d ;
d = 6 ;
a(3) = a(1) + ( 3 - 1)d;
9 = - 3 + 2d ;
12 = 2d ;
d = 6 ;
a(4) = a(1) + ( 4 - 1 )d ;
15 = -3 + 3d ;
18 = 3d ;
d = 6 ;
Then, a(n) = - 3 + ( n- 1 )6 ;
a(n) = - 3 + 6n - 6 ;
a(n) = 6n - 9 is an explicit functin rule for the sequence -3, 3, 9, 15, ...
Answer:
$857 billion
Step-by-step explanation:
Since 2006, the amount of money spent at restaurants in a certain country has increased at a rate of 5% each year. In 2006, about $580 billion was spent at restaurants.
2014-2006=8 so 2014 is 8 years from 2006
If the trend continues, the amount of money spent at restaurant in 2014 will be (1.05)^8 times that of the amount in 2006:
$580*(1.05)^8 = $856.9
About <u>$857</u> billion will be spent at restaurants in 2014 if the trend continues.
Answer:
(2, 6)
Step-by-step explanation:
Point G has a coordinate of x = 5, and y = 4, that is (5, 4).
If Lynn plots point G, such that:
G is 3 units to the left of point F, the x-coordinate of point G = 5 - 3 = 2
G is 2 units above point F, the y-coordinate of point G = 4 + 2 = 6.
Therefore, Lynn plotted point G at x = 2, and y = 6. Which is (2, 6)
