Answer:
Mean of bagel
Step-by-step explanation:
Working out each of the statically summaries Given in the option :
Mean of muffin :
Mean = Σx / n
n = sample size
(61 + 20 + 32 + 58 + 62 + 61 + 56) / 7
= 350 / 7
= 50
Mean of bagel :
Mean = Σx / n
n = sample size
(34 + 45 + 43 + 42 + 46 + 72 + 75) / 7
= 357 / 7
= 51
Hence, from the result obtained, we could see that the value of 51 summarizes the mean of bagel.
The true statement about the function f(x) = -x² - 4x + 5 is that:
- The range of the function is all real numbers less than or equal to 9.
<h3 /><h3>What is the domain and range for the function of y = f(x)?</h3>
The domain of a function is the set of given values of input for which the function is valid and true.
The range is the dependent variable of a given set of values for which the function is defined.
- The domain of the function: f(x) = -x² - 4x + 5 are all real number from -∞ to +∞
For a parabola ax² + bx + c with the vertex ![\mathbf{(x_v,y_v)}](https://tex.z-dn.net/?f=%5Cmathbf%7B%28x_v%2Cy_v%29%7D)
- If a < 0, then the range is f(x) ≤
![\mathbf{y_v}](https://tex.z-dn.net/?f=%5Cmathbf%7By_v%7D)
- If a > 0, then the range f(x) ≥
![\mathbf{y_v}](https://tex.z-dn.net/?f=%5Cmathbf%7By_v%7D)
The vertex for an up-down facing parabola for a function y = ax² + bx + c is:
![\mathbf{x_v = -\dfrac{b}{2a}}](https://tex.z-dn.net/?f=%5Cmathbf%7Bx_v%20%3D%20-%5Cdfrac%7Bb%7D%7B2a%7D%7D)
Thus,
- vertex
= (-2, 9)
Range: f(x) ≤ 9
Therefore, we can conclude that the range of the function is all real numbers less than or equal to 9.

Answer:
Number = 15.
Step-by-step explanation:
Given : If you multiply a number by 3 and then subtract 5, you will get 40.
To find : what is the number.
Solution : We have given if you multiply a number by 3 and then subtract 5, you will get 40.
According to question :
Let the number = x
Multiply is with 3 = 3x
Subtract 5 from it we get 40 .
3x -5 = 40
On adding both sides by 5
3x = 45 .
On dividing both sides by 3
x = 15.
Therefore, Number = 15.
Your answer is going to be letter B. the minimum point is in a negative spot so that cancels out A and D. the inside of the parabola is pointing up so that makes the answer B.
