Answer:
Hello! Here is your answer
Step-by-step explanation:
112=4(28)
a=4b
You can only have one variable so:
Combine b to a:
a-b=84
4b-b=84
Divide both sides by 3:
3b/3=84/3
b=28
But that is not it:
Sum of both cards:
a+b
a=112
b=28
112+28=140
= 140
I hope I was of help. If not please let me know! Thank you! Good luck!
It doesn't give any answers? I think the first one is 14 the second one is -4 and the third one is 10
Answer:
Find in Step by Step
Step-by-step explanation:
x-intercept = 26/-4 = 13/-2 = -6.50000
y-intercept = 26/1 = 26.00000
Slope = 8.000/2.000 = 4.000
Equation at the end of step 1 :
(y - 6) - 4 • (x + 5) = 0
Step 2 :
Equation at the end of step 2 :
y - 4x - 26 = 0
Step 3 :
Equation of a Straight Line
3.1 Solve y-4x-26 = 0
Answer:
<em>f = g/ g+1</em>
Step-by-step explanation:
Remove Parenthesis.
<em>fg - 1 x 5 = g - 1 x f - 1 x 5</em>
Cancel <em>-1 x 5</em> on both sides.
<em>fg = g - 1 x f</em>
Simplify <em>1 x f</em> to f.
<em>fg = g - f</em>
Add <em>f </em>to both sides.
<em>fg + f = g</em>
Factor out the common term <em>f.</em>
<em>f (g + 1) = g</em>
Divide both sides by <em>g + 1</em>
<em>f = g/ g + 1</em>
Answer:
99.7% of the sample proportions will fall between 0.133 and 0.307.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 0.22
Standard deviation = 0.029
99.7% of the sample proportions will fall within which of the following intervals?
Within 3 standard deviations of the mean.
Lower end: 0.22 - 3*0.029 = 0.133
Upper end: 0.22 + 3*0.029 = 0.307
99.7% of the sample proportions will fall between 0.133 and 0.307.
