deff fn [24]

Answer: He can completely decorate 11 cars

Explanation: since he puts 2 snowflakes on each of the 4 windows on one car, in total Jack uses 8 snowflakes per car. If he makes 90 snowflakes, 90 divided by 8 gives you the amount of cars he can decorate. 90/8 = 11.25, but since you can’t have .25 cars the answer is 11.

Hip Breadths and Aircraft Seats
Engineers want to design seats in commercial aircraft so that they are wide enough to fit 98% of all males. (Accommodating 100% of males would be too expensive.) Men have hip breadths that are normally distributed with a mean of 14.4 in. and a standard deviation of 1.0 in. Find P 98. That is, find the hip breadth for men that separates the smallest 98% from the largest 2%.

4v+1<4-7 for inequalities

enot [183]

4 × v + 1 - (4 - 7) < 0

4(v) + 1

Divide (÷) each side side '4'

Then subtract (-) 1 from each side

v < -1

Now we're looking for then inequality plot in: 4.000v + 4.000 < 0

Therefore, your answer would have to be
" x < -1" (:

1) Your friend Taylor missed class today and needs some help identifying solutions of systems. Explain to Taylor where to find t

Mashcka [7]

Answer:

Ques 1:

Let us consider the system of equations,

$2x+y=3$ and $3x-y=2$

It is known that 'The intersection points of the graphs of the system of equations are the solutions of the system of equations'.

So, after plotting the given graphs, we see that from the first graph,

The only intersection point is (1,1).

Thus, the solution of the system is x= 1 and y= 1.

Ques 2:

We have the functions, f(x)= 2x+1 and g(x)= 2x^2+1.

Plotting the graphs of both the functions is shown by graph 2, we see that,

The intersection points are (0,1) and (1,3)

Hence, the function have equal values only at x= 0 and x= 1 but not at x= 3.
