Systems of linear equations can only have 0, 1, or an infinite number of solutions. These two lines cannot intersect twice. The correct answer is that the system has one solution.

1/2+(3/8−1/8)^2

= 1/2+(2/8)^2

= 1/2+(1/4)^2

= 1/2 + 1/16

= 8/16 + 1/16

= 9/16

Evelyn has 12.7 quarte of fruit punch in a cooler. She pours the fruit punch into glasses. She fills 5 glasses, each with a capa
Alexus [3.1K]
There is 6.74 quarts left in the cooler.

Since 5 of the glasses have a capacity of 0.36 qt, this is a total of 5(0.36) = 1.8 qt.  The 8 glasses that have a capacity of 0.52 qt have a total of 8(0.52) = 4.16 qt.  This gives a total of 4.16+1.8 = 5.96 qt.

To find the remaining, subtract from 12.7:
12.7-5.96 = 6.74 qt.

7. A number of minor automobile accidents occur at various high-risk intersections in Teton County despite traffic lights. The T

Answer:

Modification has not reduced the number of accidents.

Step-by-step explanation:

H_0: \mu\geq0\\H_a:\mu

                                 A  B  C   D   E   F  G   H

Before modification 5  7  6   4    8   9   8   10

After modification    3  7  7   0    4   6   8    2

Difference                -2 0  1   -4   -4   -3  0   -8

Mean of differences M_d = \frac{sum}{8}=\frac{2+0-1+4+4+3-0+8}{8}=2.5

Standard deviation of differences = \sqrt{\frac{\sum(x-\bar{x})^2}{n}}=2.9277

Formula of paired t test :

t=\frac{M_d}{\frac{s}{\sqrt{n}}}\\t=\frac{2.5}{\frac{2.9277}{\sqrt{8}}}\\t = 2.4152

Df = n-1 = 8-1 =7

t critical = t_{(df, \alpha)}=t_{7,0.01}=2.998

t critical> t calculated

So, We failed to reject null hypothesis

Hence modification has not reduced the number of accidents.
