Q α r
q=kr
thus
k=q/r
when r=20, q=76
hence
k=76/20=
q=76/20r
when r=45 the value of q will be:
q=76/20×45
q=171

Answer:
The total area of the flag was 394 square inches.
Step-by-step explanation:
Given that Rainey's group designed a flag, and they used 234 square inches of green fabric, twice as much green fabric as orange fabric, and 3 times as much green fabric as yellow fabric and they had 35 sq inches of yellow fabric left, to determine the total area of the flag the following calculation must be performed:
234 + 234/2 + (234/3 - 35) = X
234 + 117 + (78 - 35) = X
234 + 117 + 43 = X
234 + 160 = X
394 = X
Thus, the total area of the flag was 394 square inches.

Step-by-step explanation:
no of times he failed = -3
points he losed = -3 x 4 = -12
no of times he need to hit the target to get 48 points = 6x
<u>equation</u>
<u>-12 + 6x = 48</u>
<u>6x = 60 </u>
<u>x = 10</u>
no of points he will gain = 10 x 6 = 60
Answer:
Both means are apprxoimately equal at 1% level of significance.
Step-by-step explanation:
Given is the information summarised below
Group Men Women
Mean 23.00 28.00
SD 5.00 10.00
SEM 1.00 1.83
N 25 30
H0: Mean of mean = mean of women
Ha: means of men < mean of women
(Left tailed test)
Since population std deviation is known but sample sizes are small t test is used.
The mean of Men minus Women equals -5.00
standard error of difference = 2.201
t = 2.2721
df = 53
p value= 0.0136
since p >0.01 at 1% significance level we fail to reject H0.
Both means are apprxoimately equal at 1% level of significance.
