4 is the GCF of the 28 and 48.
Let's find the prime factorizations of 28 and 48:
Prime factorization of 28:
28 = 2 × 2 × 7
Prime factorization of 48:
48 = 2 × 2 × 2 × 2 × 3
Now, let's identify the common prime factors of 28 and 48, which are the prime factors that appear in both factorizations:
Common prime factors: 2 × 2
To find the GCF, we multiply the common prime factors together:
GCF = 2 × 2 = 4
Therefore, the greatest commonfactor of 28 and 48 is 4.

After spending $4 on apples, Noah has $16 left. Given that each mango costs $2, he can purchase a maximum of 8 mangos.
With the given situation, Noah is planning to buy 4 apples at $1 each, costing him a total of $4. The total money Noah has is $20, so we subtract the cost of the apples from this. This leaves Noah with $20 - $4 = $16 to spend on mangos. Since each mango costs $2, we divide the remaining money by the price of each mango to find the quantity Noah can buy. So, it becomes $16 ÷ $2 = 8. Therefore, the maximum number of mangos Noah could buy, while also purchasing 4 apples, would be 8 mangos.

The residual value is -8
A residual value is the difference between the observed y-value and the predicted y-value( from the regression equation ) .
Here, the given regression equation of the line,
y = 5.2 x +18
Thus, for x = 10, the predicted value of
y = (5.2 × 10) +18
y = 52 + 18
y = 70
Now, by the given question,
For x = 10, the observed value of y = 62,
Hence, the residual for 10 = Observed value of y for 10 - Predicted value of y for 10
= 62 - 70
= -8

Answer:
The residual for 5 is -1.6
Step-by-step explanation: Hope this helps. Name me brainliest please.
A residual value is the difference between the observed y-value and the predicted y-value( from the regression equation ) .
Here, the given regression equation of the line,
y = 5.2 x - 0.4
Thus, for x = 5, the predicted value of y = 5.2 × 5 - 0.4 = 26.0 - 0.4 = 25.6,
Now, by the given table,
For x = 5, the observed value of y = 24,
Hence, the residual for 5 = Observed value of y for 5 - Predicted value of y for 5
= 24 - 25.6 = - 1.6
⇒ First option is correct.
