Dmitriy789 [7]

Answer:

405

Step-by-step explanation:

From the given information, we have 900 respondent.

The poll predicts that the incumbent will be reelected with 55 percent of the votes.

This implies that (100-55=45) percent of the respondents would not vote for the current governor or indicated that they were undecided.

Out of 900 respondents, we have

\frac{45}{100}  \times 900

= 45 \times 9 = 405

would not vote for the current governor or indicated that they were undecided.

Francis gets 6 paychecks in 12 weeks. How many paychecks does she get in 52 weeks?
Darya [45]
First, figure out how long it takes Francis to get one paycheck.
You do this by dividing the number of weeks by the number of paychecks.
12 ÷ 6 = 2
Now, you divide 52 weeks by the time it takes to get one paycheck.
52 ÷ 2 = 26
This means that Francis gets 26 paychecks in 52 weeks.

4vir4ik [10]

Answer:

\large\boxed{y-5=-4(x-3)}\\\boxed{y-8=\dfrac{1}{2}(x+1)}

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

m=-4,\ (3,\ 5)\\\\y-5=-4(x-3)

m=\dfrac{1}{2},\ (-1,\ 8)\\\\y-8=\dfrac{1}{2}(x-(-1))\\\\y-8=\dfrac{1}{2}(x+1)
