Answer:
Step-by-step explanation:
theres 4reds every 50 so do 50x4 then you times that by four 50x4=200 so do 200x4=800
Answer:
9*(6+7)
Step-by-step explanation:
First, we have to find the Greatest Common Factor (GCF), to do this we have to see all the factors of 54 and 63 and find the greatest factor that they have in common.
Factors of 54
1,2,3,6,9,18,27,54
Factors of 63
1,3,7,9,21,63
The GCF is 9 because is the greatest factor that is common to both numbers.
Now we have to divide 54/9 and 63/9
54/9 = 6
63/9 = 7
So now we can write the product of the GCF and another sum:
9*(6+7)
<em>We can prove this by solving both expressions:</em>
<em>54+63 = 9*(6+7)</em>
<em>117 = 9*13</em>
<em>117 = 117 </em>
<em>The results are equal so we prove it is right.</em>
Answer:
4560
Step-by-step explanation:
Well, first we need to understand how different time formats (for lack of a better word) are related in terms of seconds.
1 minute has 60 seconds
I hour has 3600 seconds
1 day has 86400 seconds
1 week has 604800 seconds
Now, with this information at hand, you can find out how many seconds are in X minutes or X days or X months or a year (and so on).
As for your question, we know that one minute has 60 seconds therefore 76 minutes will have (76x60) seconds
Answer:
The standard deviation of X is 0.7
Step-by-step explanation:
We are given the following distribution:
x: 0 1 2 3
P(x): 0.3 0.5 0.2 0.4
We have to find the standard deviation of X.
Formula:
Thus, the standard deviation of X is 0.7
Y= Mx+b
In the equation of a straight line,the slope is the number "m" that is multiplied on the x, and "b<span>" is the </span>y<span>-intercept (that is, the point where the line crosses the vertical </span>y<span>-axis).</span>
