All you have to do is plug it into slope-intercept form, which is y = mx + b
y = (-2)x + 4
y = -2x + 4
the answer is A
One way to solve this is to revert to integers.
Do this by moving the decimal in 1.3 to the right 6 places (indicated by the positive power value) and then 6.8 move the decimal to the right 5 places (same reason)
Now you have 1,300,000 & 680000. Subtract to get 620,000.
Now convert your product to scientific notation again by moving your decimal to the left until you are left with 6.2 x ? The question mark will be 10 to the number of places you moved the decimal. 10^5
We have 6.2 x 10^5.
It is import to note that when the decimal must be moved to the right for values less than one, the power will be negative.
Answer:
13 petunias
Step-by-step explanation:
13x7=91
9x8=72
add them and you get 163
Answer with explanation:
The 90% confidence interval (51%, 61%) for proportion means that the proportion of getting heads lie in it.
Given : Total number of times coin is tossed = 250
Number of times they got head =140
The probability of getting a head = 0.56
The confidence interval for proportion is given by :-
Given significance level : 
Critical value : 
Now, the 90% confidence interval for proportion will be :-
Hence, the given confidence interval is correct.
Add up 90 and 34
You get 124
Divide it by 2
You get 62
62 plus what is 90
Its 28
You're done !!
62 plus 28 is 90
62 minus 28 is 34
