The answer is Ms Hernandez can bring up to 6 people to the zoo.
x - <span> the number of people that she can bring to the zoo
</span><span>The parking will cost $7: a = 7
</span><span>Admission tickets will cost $15.50 per person: b = 15.50x
She can spend on parking and admission tickets </span><span>$100:
a + b </span>≤<span> 100
a = 7
b = 15.50x
7 + 15.50x </span>≤<span> 100
15.50x </span>≤<span> 100 - 7
15.50x </span>≤<span> 93
x </span>≤<span> 93 / 15.50
x </span>≤ 6
Answer:
The specificity of this test is expressed as:________
70%.
Step-by-step explanation:
a) Data and Calculations:
TEST RESULTS Disease Present Disease Absent Total
Positive for Factor X 40 60 100
Negative for Factor X 10 140 150
Total 50 200 250
Negative for X and Disease Absent = 140/200 * 100
= 0.7 * 100
= 70%
b) The specificity refers to the percentage of people who test negative for a specific disease among a group of people who do not have the disease. No test is 100% specific because some people who do not have the disease X will test positive for it (false positive). Therefore, we are testing for the true negative, that the 140 people who tested out of the 200 people who do not have the disease.
Take 180 and subtract the sum of the two given angle, the answer is 62
