62500 - 56100 = 6400 - number of retrivers u lost per year.
Answer need to be lower then 62,5 and 56,1 thousand so no (A) and not (D)
Number is reduce by 6400 and starting amount was 62500, 2 zeros and end must stay there in answer so not (B)
Then it must be (C)
Or u can calculate 62500 - 9*6400 = 4900
Answer:
(0.46, 0.52)
Step-by-step explanation:
The formula for Confidence Interval with Proportion
CI = p ± z × √p(1 - p)/n
Where
p = Proportion = x/n
x = 346
n = 706
p = 346/706
p = 0.49
z = z score of Confidence Interval 90% = 1.645
Therefore:
CI = 0.49 ± 1.645 × √0.49(1 - 0.49)/706
CI = 0.49 ± 1.645 × √0.49 × 0.51/706
CI = 0.49 ± 1.645 × 0.0188139843
CI = 0.49 ± 0.0309490042
Hence:
Confidence Interval is
0.49 - 0.0309490042
= 0.4590509958
≈ 0.46
0.49 + 0.0309490042
= 0.5209490042
≈ 0.52
Therefore , the confidence interval of the population proportion is
(0.46, 0.52)
Hello, it would be the sqrt of 218, which rounded to the hundredths is around 14.77 cm. hope this helps!

Answer:
y = -7x + 33
Step-by-step explanation:
<u>Use the Point Slope Form: (y - y1) = m(x - x1)</u>
<u />
<u>Step 1: Find the Slope</u>
Slope = 
Slope = 
Slope = 
Slope = 
Slope = -7
<u>Step 2: Plug into the point slope form</u>
(y - 5) = -7(x - 4)
y - 5 + 5 = -7x + 28 + 5
y = -7x + 33
Answer: y = -7x + 33
