Rocky ate 42 cups of dog food. Since there are 7 days in a week, 21 cups were eaten per week (3x7). Since the question is asking for the amount in two weeks, you multiply 21x2 to get 42.

Answer:

42 cups of dog food.

Step-by-step explanation:

Rocky ate 3 cups of dog food each day for two weeks, there's 7 days in a week, if you multiply 14 ( number of days in 2 weeks) and 3( the number of dog food each day) you would get 42 because 7 days are in 1 weeks and if you add another 7 days, you would get 14 days and by multiplying that by 3, the dog food Rocky ate each day, you would get 42, the answer to your question. Hope this answers your question!

Answer:

Class Boundary = 1 between the sixth and seventh classes.

Step-by-step explanation:

Lengths (mm) Frequency

1. 140 - 143 1

2. 144 - 147 16

3. 148 - 151 71

4. 152 - 155 108

5. 156 - 159 83

6. 160 - 163 18

7. 164 - 167 3

The class boundary between two classes is the numerical value between the starting value of the higher class, which is 164 for the 7th class in this case, and the ending value of the class of the lower class, which is 163 for the 6th class in this case.

Therefore the class boundary between the sixth and seventh classes

= 164 - 163 = 1

Therefore Class Boundary = 1.

It can be seen that class boundary for the frequency distribution is 1.

If we take the difference between the lower limits of one class and the lower limit of the next class then we will get the class width value.

Therefore, Class width,

w = lower limit of second class - lower limit of first class

= 144 - 140

= 4

Write the equation for the quadratic function in the graph

Hoochie [10]

Answer:

${x}^{2} - 16 = 0 \: is \: the \: equation$

Step-by-step explanation:

$x = - 4 \\ or \: x = 4$

$(x + 4) = 0 \: or \: (x - 4) = 0 \\ (x + 4)(x - 4) = 0 \\ open \: the \: bracket$

$x(x - 4) + 4(x - 4) = 0$

${x}^{2} - 4x + 4x - 16 = 0 \\ {x}^{2} - 16 = 0$

marin [14]

Answer:

If you shoot the bullet off the back of the car , the bullet will still be moving away from you and the gun at 1,000 mph, but now the speed of the train will subtract from the speed of the bullet. Relative to the ground, the bullet will not be moving at all, and it will drop straight to the ground.
