Answer:
The length of the leg is 13.416
Step-by-step explanation:
To calculate one side of a right triangle from the other 2 sides we have to use Pythagoras
h = hypotenuse = 18
a = leg 1 = 12
b = leg 2 =
h² = a² + b²
we replace the known values and solve
18² = (12)² + (a)²
324 = 144 + (a)²
324 - 144 = (a)²
324 - 144 = (a)²
√180 = a
13.416 = a
The length of the leg is 13.416
Answer:
21
Step-by-step explanation:
x2 + 3.4y, when x = 2, y = 5
(2)2+3.4(5)
2×2+3.4×5
4+5×3.4
4+17
21
Hope it helps! :)
Slope-intercept form:
y = mx + b
Your equation in slope-intercept form (which you already have :)):
y = 3/5x - 4
So your slope is m = 3/5
Do you need help finding the y-intercept or x-intercept? I hope this helps and answers your question! Have a lovely day!
Answer:
H0 : flavor and serving size are independent
H1: Flavor and serving size are not independent
Step-by-step explanation:
The claim or hypothesis is to test if there is a relationship between the different types of flavor (vanilla, strawberry and chocolate) and the size (large, medium and. Small) being ordered. This is the the Alternative hypothesis, in other words to establish that flavor type and size are not independent, (that is the two variables are correlated).
The Null hypothesis will be the opposite of the alternative, establish that both variables are independent.
Hence ;
Null hypothesis ; H0 : flavor and serving size are independent
Alternative ; H1: Flavor and serving size are not independent
50=t/2+8
50-8=t/2
42=t/2
2×42=t
84=t
check: 50=84/2+8
50= 42+8
50=50
