Answer: -2.12°C
Step-by-step explanation:
Let x denotes the reading of the thermometers .
We assume that the readings on the thermometers are normally distributed.
Let a be the reading that separates the rejected thermometers from the others.
Given: Population mean : 
Standard deviation: 
Also, 
By using the z-table , the z-value corresponds to the p-value (one -tailed)0.017 is 
.
Now, 
i.e. 
i.e. 
For left tailed , 
It means the reading that separates the rejected thermometers from the others = -2.12°C.
Answer:
C
Step-by-step explanation:
It makes the equation false because the answer on one side is false.
2(-4) + 0 = -8(-4) - 0 = -4
-8 + 0 = 32 - 0 = -4
-8 = 32 = -4
-8 does not equal 32. The equation is unbalanced.
So, the answer will be C) The ordered pair (−4, 0) is not a solution to the system because it makes at least one of the equations false.
Hope this helps

Answer:
y = -2 ( x - 1)² + 5
Step-by-step explanation:
formula for the vertex: y = a (x - h)² + k where (h, k) is the vertex
y = −2x^2 + 4x + 3
y = -2 (x² - 2x + 1) + 5
y = -2 ( x - 1)² + 5
h = 1
K = 5
Depends on how big of rows and columns (side to side or up and down) 3 by 4 for black and white and 3 by 6 for color just reverse the numbers so it'll be in stead 4 by 3 and 6 by 3 hope this makes sense
Answer:
Hello! answer: 5
Step-by-step explanation:
What you do to find the answer for these is do a^2+b^2=c^2 Basically meaning 4 × 4 + 3 × 3 will equal a number that you then find the suare root of square root just meaning a number multiplied by itself to equals that number so...
4 × 4 = 16
3 × 3 = 9
16 + 9 = 25
√25 = 5
5 × 5 = 25 therefore c = 5 hope that helps!
