In 2015, there were 310 rats that were counted living in a park.
the rats and the population decreased by 70%
What are percentage?
percentage is the ratio of composition of matter to the overall composition of matter multiplied by 100.
Since rat decreased by 70 %,
= 310 x 70 / 100
= 217
Now the decrease in rats = 310 - 217
anticipated rats in the park = 93
Thus the 93 rats can be anticipated in the park now.

Answer: D. [tex]y=\frac{1}{9} x^{2}[/tex]
Step-by-step explanation: The smaller the coefficient of a fraction by the quadratic function (the x squared value), the more narrow the graph becomes. 1/4 is larger than 1/9 and the other two whole numbers are still larger than 1/9. Even though -1 is less than 1/9, this only makes the graph flip, not make it any more narrow. Fractions are what squeeze graphs, negatives do not make a difference (i.e. -1/4 is the same size of narrowness as 1/4).

Step-by-step explanation:
You know EOF is equal to COD so you can say
x+8=63

x=55 degrees
Next
63 and DOE add up to 180
DOE = 180-63
DOE = 117 Degrees

Answers
Answer:
a) Upper Control Limit = 0.10
Lower Control Limit = 0.01
b) The tech assistance process is stable and in control.
Step-by-step explanation:
Given - After a number of complaints about its tech assistance, a
computer manufacturer examined samples of calls to determine
the frequency of wrong advice given to callers. Each sample
consisted of 100 calls.
SAMPLE 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
Number of errors 5 3 5 7 4 6 8 4 5 9 3 4 5 6 6 7
To find - a. Determine 95 percent limits.
b. Is the tech assistance process stable (i.e., in control)
Proof -
z = 95% confidence interval
= 1.96
⇒z = 1.96
Proportion of defects,P = total defectives/total observations
= 0.0544
⇒P = 0.0544
Now,
Q = 1-P
= 0.9456
⇒Q = 0.9456
Now,
Average sample size, N = 100
Standard deviation = [tex]\sqrt{\frac{P.Q}{N} }[/tex]
= 0.0227
Now,
Upper Control Limit = P + z(Standard deviation)
= 0.0988
⇒Upper Control Limit = 0.0988 ≈ 0.10
And
Lower Control Limit = P - z(Standard deviation )
= 0.0099
⇒Lower Control Limit = 0.0099 ≈ 0.01
∴ we get
Upper Control Limit = 0.10
Lower Control Limit = 0.01
b.)
Now,
it is clear that the fraction defective values are wit in upper an lower control limits.
So, The tech assistance process is stable and in control.
The sum of 43 and z is equal to 72.98. Enter the equation that represents the description.
Answers
sum is an answer to an addition problem, so we have to add 43 and z. z+43=72.98
Subtract 43 on both sides.
z=29.98

hope it helps
Answer:
43 + z = 72.98
Step-by-step explanation:
Sum meaning add the two (or more numbers together) we get 43+ z = 72.98
If you're trying to find "z" simply subtract 43 from 72.98 to get 29.98 as z

What is the value of 4)1/8 divided by 5)1/2
Answers
Answer:
I'm assuming that you meant to type: The question is x/5=1/2+1/8 ; X= ?
If so, we're solving for x.
x/5 = 1/2 + 1/8
2 is a factor of 8, so let's start with common denominators.
x/5 = 1/2 *(4/4) + 1/8
x/5 = 4/8 + 1/8
x/5 = 5/8 As long as we just need to know the value of x, let's use inverse operations.
x/5 *5 = 5/8 *5
x = 25/8 or 3.125
