Basiclly, we look at the 2 points below and find the distance between them, then we match
d=

when finding the distance between points (x1,y1) and (x2,y2)
if the x values, or y values are same, you don't need the distance formula, just use logic
(-10, 2) and (-2, 2)
the y value is the same so find the distance between the x values
from -10 to -2 is 8
8 matches with this one
(-3, -1) and (5, 1)
use distance formula
d=

=√68
(-3, -2) and (1, 3)
input
d=

=√41
(-3, -5) and (-2, -4)
input
d=

=√2
(0, 0) and (5, 5)
input
d=

=√50
(1, 2) and (1, -10)
x values are same so find distance between 2 and -10
answer is 12
(1, 2) and (5, 2)
y values are same
find distance between 1 and 5
answe ris 4
(2, 3) and (10, 9)
input
d=

=10
ANSWERS (because the spacing has gone wierd)
(-10, 2) and (-2, 2)=8
(-3, -1) and (5, 1)=√68
(-3, -2) and (1, 3)=√41
(-3, -5) and (-2, -4)=√2
(0, 0) and (5, 5)=√50
(1, 2) and (1, -10)=12
(1, 2) and (5, 2)=4
(2, 3) and (10, 9)=10
Answer:
375 calories
Step-by-step explanation:
given:
1.6 km ----> burns 120 calories
1 km ----> burns (120 / 1.6) calories
5 km ----> burns (120 / 1.6) x 5 = 375 calories
Answer:
P (z) = -1.5094
Step-by-step explanation:
We have to find P-value (that means we have to calculate the test value to evaluate a proportional hypothesis
From problem statement
P₀ = 0,44 44 % from publisher report
The claim :
350 = n random sample
P = 0,40 40 %
To calculate P value
P ( z ) = ( P - P₀ ) / √(P₀*Q₀)/n
then P ( z ) = - 0.04 / √(0,44)(0,56)/350 P(z) = - 0.04/0,02
P (z) = -1.5094
