Answer:
-5 = -9
-2 = -6
0 = -4
4 = 0
Step-by-step explanation:
You substitute each value for x and then solve the equation. (Please give me brainliest)
Answer:
the black paint is of 200 ml
Step-by-step explanation:
first he wanted grey paint by mixing 600 ml of both colour so he reduced black paint by 7:12 ratio an we get difference of 3 with that ratio so dividing 600 by 3 and we get amount of blacl paint removed
Answer:
y = 5x - 3
Step-by-step explanation:
equation of a straight line is <em>y = mx + b </em>where m=slope and b=y-intercept
in this case m=5 and b= -3
y = mx + b
y = 5x - 3
Answer:
a) P value = 0.0013
b) No, it is not plausible that the silicon content of the water is no greater than it was 10 years ago
Step-by-step explanation:
The null hypothesis here is “Mean is equal to 5” while alternate hypothesis is that “Mean is greater than 5”
Given
Mean = 5, x’ = 5.4 and sigma = 1.2 and n = 85
Z = x-u’/sigma/sqrt n
Substituting the given values, we get –
Z = 3.02
A) P value = 0.0013 which is less than 0.05 and thus we will reject the null hypothesis
B) There is enough evidence to reject the null hypothesis
