6 0

Answer:

Jose stretched the taffy the farthest and Maria stretched it the least

Step-by-step explanation:

Distance stretched by George = 3 feet

Distance stretched by Jose is 1\dfrac{1}{3} times as much as George so

3\times 1\dfrac{1}{3}=3\times\dfrac{4}{3}=4\ \text{feet}

Distance stretched by Jose is 4\ \text{feet}

Maria streched the taffy \dfrac{2}{3} times as George

3\times \dfrac{2}{3}=2\ \text{feet}

Maria stretched the taffy by 2\ \text{feet}

Sally stretched it \dfrac{6}{6} so 1\ \text{feet}

So, Jose stretched the taffy the farthest and Maria stretched it the least.

What is the surface area of the figure shown?
Shalnov [3]

Answer:

The surface area of the figure = 962 ft²

Step-by-step explanation:

The rectangle dimensions and its area given below

Dimensions       Number         Area

12 x 7                2                   12 x 7 x 2 = 168

16 x 7                1                    16 x 7 = 112

12 x (16 + 5)     1                    12 x 21 = 252

16 x 12              1                    16 x 12 = 192

16 x 13              1                     16 x 13 = 208

Triangle dimensions

Dimensions           Number         Area

b = 12  & h = 5       2                bh/2 = (12*5)/2  = 30

To find total area

Total area = 168 + 112 + 252 + 192 + 208 + 30 = 962 ft²

Two boats started to move towards each other from two docks, located 30 miles apart. One boat moved at a speed of 3 miles per ho
blagie [28]

Answer:

3.333 hours

Step-by-step explanation:

Given the total distance is 30 miles, and boat 1 travels at 3 mph and boat 2 travels at 6 mph, and the time for both is the same. Distance is speed S times time T so

30 = D(boat 1) + D(boat 2)

30 = (S1 * T) + (S2 * T)

30 = 3T + 6T

30 = 9T

3.333 = T

What are the hypotheses for testing to see if a correlation is statistically significant?
Andrew [12]

Answer:

Step-by-step explanation:

For testing of significance of correlation coefficient denoted by r, we create hypotheses in three ways

They are one tailed, two tailed.  One tailed can be stated as right tailed and also left tailed.

The null hypothesis would normally be as r=0

Verbally we can say this there is no association between the dependent and independent variable (linear)

Against this alternate hypothesis is created as

either r not equal to 0

or r>0 or r<0

If r not equal to 0, we say two tailed hypothesis test

If r>0 is alternate hypothesis, it is right tailed test

If r<0 is alternate hypothesis, then it is left tailed test.

Find the distance between each pair of parallel line<br>y=x-6 and y=x+8
myrzilka [38]
Both these lines are linear and have the same slope, just different y-intercepts. This means one line is shifted higher than the other. y=x+8 is 14 units higher than y=x-6. The answer to you question therefore is 14 units!
