Answer:
Weight of dog: 34 pounds,
Weight of cat: 12 pounds.
Step-by-step explanation:
Let d represent weight of dog and c represent weight of cat.
We have been given that a dog weighs two pounds less than three times the weight of a cat.
3 times weight of cat: 
We can represent the given information in an equation as:
We are also told that the dog also weights twenty-two more pounds than the cat. We can represent the given information in an equation as:
Equate both equations:
Therefore, the weight of cat is 12 pounds.
Substitute in equation (2)
Therefore, the weight of dog is 34 pounds.
Answer:
Therefore we fail to reject the Null hypothesis 
Because the is no sufficient evidence to support the claim of the alternative hypothesis 
Step-by-step explanation:
From the question we are told that
Sample size 
Mean time 1 
Mean time 2 
Standard deviation 
Standard deviation 
Level of significance 0.05
The null hypothesis is 
Alternative hypothesis 
Generally the test statistics is mathematically represented as
From Table the Z-critical value at 
Therefore
Zcal> Zcritical
(-0.43)=(-1.645)
Generally we fail to reject the null hypothesis at 
Therefore we fail to reject the
Because the is no sufficient evidence to support the claim of

Answer:
A
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x + 4)² + (y - 1)² = 25 ← is in standard form
with centre = (- 4, 1 ) and r = 
= 5 → A
0.07 and 0.3 the fraction would be 7\100 and 3\10
