Answer: -7920
Step-by-step explanation: 33x-6x40= -7920
Answer: 5 times
Step-by-step explanation:
Let the number of times that he saved $75 be x.
Let the number of times that he saved $150 be y.
Therefore, based on the information given in the question, we can form an equation which will be:
x + y = 8 ...... i
75x + 150y = 825 ....... ii
From equation I,
x + y = 8
y = 8 - x....... iiii
Put equation iii into ii and this will be:
75x + 150y = 825
75x + 150(8 - x) = 825
75x + 1200 - 150x = 825
75x - 150x = 825 - 1200
-75x = -375
x = 375/75
x = 5
He saved $75 5times from his paycheck.
Answer:
x = 1/2
Step-by-step explanation:
<em>Simplify the sides of the equation...</em>
<em>10x + 3 = 4x + 6</em>
<em>Subtract 3 from both sides...</em>
<em>10x = 4x + 3</em>
<em>Subtract 4x from both sides...</em>
<em>6x = 3</em>
<em>Divide by 6</em>
<em>x = 1/2</em>

Answer:
a) F(2)=0.30
b)P(X>3)=0.7
c)P(2≤X≤5)=0.67
d)P(2<X<5)=0.71
Step-by-step explanation:
a) F(2)=P(X≤2)=0.30
F(2) is given in the probability distribution
b) P(X>3)=1-P(X≤2)=1-F(2)=1-0.3=0.7
P(X>3)=0.7
c)P(2≤X≤5)=?
As we know that P(a≤X≤b)=F(b)-F(a)=P(X≤b)-P(X≤a)
So,
P(2≤X≤5)=P(X≤5)-P(X≤2)=F(5)-F(2)=0.97-0.3=0.67
P(2≤X≤5)=0.67
d)P(2<X<5)=P(1≤X≤4)=P(X≤4)-P(X≤1)=F(4)-F(1)=0.91-0.2=0.71.
P(2<X<5)=0.71
Y=2w-6 that's the best answer I think
