2x = 76
x = 76/2 = 38

2(76) + 2y = 360
2y = 360 - 152 = 208
y = 208/2 = 104

x = 38, y = 104.

Ricky needs 3 1/4 cups of sugar to make muffins. He already has 2 2/4 cups. How many more cups of sugar does he need? (12-9)

As I understood your typing 3 1/4 means $3 \frac{1}{4}$ So,

 $3 \frac{1}{4} -2 \frac{2}{4} = \frac{13}{4} - \frac{10}{4}= \frac{3}{4}$

Answer:

A. The y intercept the y coordinate when the line passes through the point that is on the y coordinate and the x is 0. In this context, the y intercept is 10.

B. The slope is the number of units the line goes up every number of units it goes to the right. This line goes up 50 every 20 units to the right so the slope is 50/20 which simplifies to 5/2

C. The equation is y = 5/2x + 10

Parallel lines are in the same plane, never intersect, and have the same slope.

9.4 The heights of a random sample of 50 college stu- dents showed a mean of 174.5 centimeters and a stan- dard deviation of 6.9

gladu [14]

Answer: a) (176.76,172.24), b) 0.976.

Step-by-step explanation:

Since we have given that

Mean height = 174.5 cm

Standard deviation = 6.9 cm

n = 50

we need to find the 98% confidence interval.

So, z = 2.326

(a) Construct a 98% confidence interval for the mean height of all college students.

$x\pm z\times \dfrac{\sigma}{\sqrt{n}}\\\\=(174.5\pm 2.326\times \dfrac{6.9}{\sqrt{50}})\\\\=(174.5+2.26,174.5-2.26)\\\\=(176.76,172.24)$

(b) What can we assert with 98% confidence about the possible size of our error if we estimate the mean height of all college students to be 174.5 centime- ters?

Error would be

$\dfrac{\sigma}{\sqrt{n}}\\\\=\dfrac{6.9}{\sqrt{50}}\\\\=0.976$

Hence, a) (176.76,172.24), b) 0.976.
