Answer:
Step-by-step explanation:
3/4 x 28=21 Madilyn built 21 toys.
1/7 x 28=4 Penelope built 4 toys.
21+4=25 25 toys have been built altogether.
28-25=3
There are 3 toys left to build.
Answer:
It's about 6,111 kids per second.
Step-by-step explanation:
1 hour = 60 minutes
1 minute = 60 seconds
60*60=3600
1 hour = 3600
hourly rate -> 22,000,000 kids/hr
secondly rate -> 22,000,000/3600 ≈ 6,111
secondly rate -> 6,111 kids/second
Answer:
x = 83.7 units
Step-by-step explanation:
- given adjacent: 56, given angle: 48°, asked to find hypotenuse, x?
Using cosine rule:
→ adjacent/hypotenuse = cos(∅)
→ 56/hypotenuse = cos(48)
→ hypotenuse = 56/cos(48)
→ hypotenuse = 83.7 units
The answer is $15.86
You find this by doing 2 and 3/5 or 2.6 times 6.10 getting an answer of $15.86
Answer:
a
b
c
With the result obtained from a and b the manager can be 95 % confidence that the proportion of the population that complained about dirty or ill-equipped bathrooms are within the interval obtained at a
and that
the proportion of the population that complained about loud or distracting diners at other tables are within the interval obtained at b
Step-by-step explanation:
From the question we are told that
The sample size is
The number that complained about dirty or ill-equipped bathrooms is
The number that complained about loud or distracting diners at other tables is
Given that the the confidence level is 95% then the level of significance is mathematically represented as
Next we obtain the critical value of from the normal distribution table , the value is
Considering question a
The sample proportion is mathematically represented as
=>
=>
Generally the margin of error is mathematically represented as
The 95% confidence interval is
Considering question b
The sample proportion is mathematically represented as
=>
=>
Generally the margin of error is mathematically represented as
The 95% confidence interval is
