Answer:

The probability that at least one is a boy is 0.525

Step-by-step explanation:

P(Baby being a girl) = 0.475

Now, if A is any arbitrary event . Then:

as we know P(A)+ P(not A) = 1

⇒ P(A not happening)  = 1 - P(A event happening)

Also,  P( baby not being a girl) = P(baby being a boy)

So,  P(baby being a boy)  = 1 - P( baby being a  girl)

                                          = 1 - 0.475   = 0.525

Hence,  the probability that at least one is a boy is 0.525

We know that
The subtraction property of equality<span> tells us that if we subtract from one side of an equation, we also must subtract from the other side of the equation to keep the equation the same

that means

if a=b  and  c=d
a-c=b-d

</span>then 
<span>−8x+4y=0----------> equation 1
a=(-8x+4y)    b=0

−8x+7y=6----------> equation 2
c=(-8x+7y)   d=6

therefore
</span>
(-8x+4y)-(-8x+7y)=0-6
-8x+4y+8x-7y=-6
-3y=-6

the answer is the option

hich uses the​ high-low method to analyze cost​ behavior, has determined that machine hours best predict the​ company's total ut
Crank

Answer:

1)- Variable utilities cost per machine hour = 1.6 per machine hour

2)- Fixed cost = 1740

3)-Total cost on 1220 Machine hour will be

= 3692

Step-by-step explanation:

1) CALCULATE VARIABLE UTILITIES COST PER MACHINE HOUR :

Variable utilities cost per machine hour = Change in cost/high machine hour-low machine hour

=4076-3388/1460-1030

Variable utilities cost per machine hour = 1.6 per machine hour

2) Fixed cost = Total cost-variable cost

= 3388-(1030*1.6)

Fixed cost = 1740

3) Total cost on 1220 Machine hour will be (1220*1.6+1740) = 3692

Can anyone help me please, I will mark brainliest to the right answer
adoni [48]

Answer:

A

Step-by-step explanation:

First 4 sets of (x, y) show that when x increases 2, y increases 3. It seems the relationship is linear. But last 2 set show that x increases 1, y increases 3. So the relation is NOT linear

Need help to write equations for 5, 6 &amp; 7
hoa [83]

Read my note at the end of problem 5 in another post.
You already know this table represents an exponential function
since each y-coordinate is always the previous y-coordinate multiplied by 6.
That means b = 6, and you have
y = a(6)^x
Now we find "a". When x = 0, y = 5. That means a = 5.
The equation is

y = 5(6)^x
