Answer:

It will take 12 sheets of tile to cover the whole counter.

Step-by-step explanation:

We can start by dividing the counter into 2 rectangles.

Area of the top rectangle

=length⋅width

=2⋅4

=8 ft

Area of the bottom rectangle

=length⋅width

=2⋅5

=10 ft

We can find the total area of the counter by adding.

8 +10=18 ft

Each sheet covers 1.5\text{ ft}^21.5 ft

1, point, 5, space, f, t, start superscript, 2, end superscript. To find the total number of sheets needed to cover the whole counter, we can divide.

18/1.5=12 .

Find the slope and y-intercept of the line in each graph

seraphim [82]

Answer:

slope: 1; y-intercept: 3

Step-by-step explanation:

The y-intercept is the y-value where the graph crosses the vertical y-axis. That value is 3.

The slope is the "rise" divided by the "run" for the graph. Here, the graph goes up 1 unit for each unit to the right, so the slope is ...

m = rise/run = 1/1 = 1

The slope is 1, and the y-intercept is 3.

What is a reasonable estimate for the solution? O (1,-3/4) O (-3/4,1) O (-1,3/4) O (3/4,-1)

Zina [86]

Answer:

See Explanation

Step-by-step explanation:

Your question is incomplete, as the equations or graph or table(s) were not given.

However, I'll give a general way of solving this.

Take for instance, the equations are:

$y = \frac{4}{3}x - 1$

$y = \frac{2}{3}x - \frac{1}{2}$

To do this, we start by equating both equations.

$y = y$

i.e.

$\frac{4}{3}x - 1= \frac{2}{3}x - \frac{1}{2}$

Collect Like Terms

$\frac{4}{3}x - \frac{2}{3}x= 1 - \frac{1}{2}$

Take LCM

$\frac{4x- 2x}{3}= \frac{2 - 1}{2}$

$\frac{2x}{3}= \frac{1}{2}$

Cross Multiply

$2x * 2 = 3 * 1$

$4x = 3$

Make x the subject

$x = \frac{3}{4}$

Substitute 3/4 for x in $y = \frac{4}{3}x - 1$

$y = \frac{4}{3} * \frac{3}{4} - 1$

$y = 1 - 1$

$y = 0$

Hence:

$(x,y) = (\frac{3}{4},0)$

At a university, 12% of students smoke. Calculate the expected number of smokers in a random sample of 140 students from this un

Masteriza [31]

Answer:

a) The expected number of smokers in a random sample of 140 students from this university is 16.8 smokers.

b) No, it is unlikely that smoking habits and waking up early to go to the gym on Saturday are independent.

Step-by-step explanation:

To calculate the expected numbers of smokers in a sample with size n=140 and proportion p=12%, we use the expected value of the binomial distribution:

$E(x)=n\cdot p=140\cdot 0.12=16.8$

The expected number of smokers in a random sample of 140 students from this university is 16.8 smokers.

If we take a sample at the opening of the gym, the sample is not expected to be representative of the population of the students. Most of the students that go to the gym usually have healthy habits, so the proportions of smokers is expected to be lower than the average of the university population.
