Naddik [55]

Answer:

(3138.29, 3705.11)

Step-by-step explanation:

Given that for sample size of n = 50 male athletes from eight Canadian sport centers surveyed, the average caloric intake was 3077.0 kilocalories/day with a sample standard deviation of 987.0.

The recommended amount = 3421.70

To construct 95% confidence interval

Since population std deviation is not known we use t critical value for degree of freedom 50-1 =49

t critical = 2.010

Hence margin of error = $2.010*\frac{987}{\sqrt{50-1} } \\=283.41$

Confidence interval lower bound = $3421.70-283.41\\=3138.29$

Confidence interval upper bound = $3421.70+283.41\\=3705.11$

Conf interval = $(3138.29, 3705.11)$

Lianne charged twice as much to walk a large dog than she did to walk a small dog. This week she had time to was 10 small dogs a

guapka [62]

Well she charged twice as much to walk large then small. Let s be small and l be large.
We we know that
l = 2s

we also know that she wants to make 100 so
xl + ys = 100

Where where x is number of large and y is number of small. it says she walked 10 small and 5 large so
5l + 10s = 100

substitute 2s for l because they are same value as shown in first equation I made
5 (2s) + 10s = 100
10s + 10s = 100
20s = 100
s = 5

we can now solve for l
l = 2s
l = 2 * 5
l = 10

So s is 5 and l is 10.

Please help me answer this !

Answer:

$y = -\frac{1}{2}x + 4$

Step-by-step explanation:

The equation of the line can be written in slope-intercept form, as y = mx + b.

We need to find the slope (m) and the y-intercept (b) of the line, then plug their values into the slope-intercept equation, to find the equation of the line shown.

y-intercept (b) = the point where the line intercepts the y-axis = 4

Using two points on the line, say, (0, 4) and (2, 3):

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{3 - 4}{2 - 0} = \frac{-1}{2} = -\frac{1}{2}$

m = -½.

Substitute m = -½, and b = 4 into y = mx + b.

The equation of the line would be:

$y = -\frac{1}{2}x + 4$
