Answer:
80%
Step-by-step explanation:
Divide 24÷30 to obtain a decimal value. Then multiply the result by 100. This will move the decimal 2 places to the right. 0.8×100= 80%
Answer:
There is a positive correlation between the number of hours spent on homework and the test scores. So, the more homework you do, the better your test score.
Step-by-step explanation:
The data given is representative of a scatter plot, which shows a relationship with two sets of data that, when using a line of best fit, will show either a positive correlation (increasing), a negative correlation (decreasing) or no correlation (the data shows no overall pattern). In this case, you can see that the overall pattern of data is increasing, or a positive correlation. Which means that, in general, the more hours of homework you do, the more likely you are to receive a better test score.
Answer:
D. $66.23
Step-by-step explanation:
The sale discounts your purchase by half the price of a pair of pants, so you pay for 2.5 pairs of pants. The sale price of the pants is then ...
$24.99 × 2.5 = $62.48
The added tax multiplies this value by 1.06, so you pay ...
1.06 × $62.48 = $66.23
_____
<em>Comment on the answer</em>
Whether you pay $66.23 or $66.22 depends on how the discount is calculated. If you get the benefit of the half-penny (the discount is rounded up), then the sale price is $62.47 and the total is $66.22.
Answer:
k=1/4
Step-by-step explanation:
x² - 5kx+ k=0 ....(1)
suppose 2 roots: a and 4a
(x-a)(x-4a)=0
x² - 5ax + 4a² = 0 ....(2)
compare (1) and (2): -5a = -5k a=k
4a² = k 4a² = a (substitute)
a(4a-1) = 0
a = 0 or a = 1/4 (if a=0 k=0 and x=0 is not the solution)
a = 1/4 k = 1/4
(a₂ = 1/4 * 4 = 1)
