Answer:
Hello your question is incomplete attached below is the missing part of the question
Regular Exercise N Mean Std Dev
Yes 35 48.5 12.5
No 120 56.9 11.9
answer : ( -12.968, -3.832 )
Step-by-step explanation:
To generate a 95% confidence interval
first step :
Assume population variance is equal we will calculate the number of degrees of freedom
df = n1 + n2 - 2 = 35 + 120 -2 = 153
second step:
Given : critical value = 0.05 , df = 153
hence Tc = 1.976
assuming the population variance is equal calculate pooled std as ( attached below )
Sp = 12.036
third step :
calculate the standard error
Se = [tex]Sp\sqrt{\frac{1}{n1} +\frac{1}{n2} }[/tex]
n1 = 35
n2 = 120
Sp = 12.036
hence Se = 2.312
final step
Compute the 95% confidence interval = ( -12.968, -3.832 )
attached below is the detailed solution

Step-by-step explanation:
A charity bingo game costs $2 per round and has a $13 entry fee for an adult. It costs $3 per round and a $10 entry fee for a child. For how many rounds of bingo are the costs the same for an adult and a child?
2
3

Answer:
B=3
Step-by-step explanation:
Use a graphing calculator and type in these toe equations
y=2x+13
y=3x+10
and the point they intersect will say (3,19) and the answer is 3
For 3 rounds of bingo, the costs will be the same for an adult and a child option second is correct.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
A charity bingo game costs $2 per round and has a $13 entry fee for an adult. It costs $3 per round and a $10 entry fee for a child.
Let's suppose, for x rounds of bingo, the costs will be the same for an adult and a child.
For x rounds, cost for adult:
= 2x + 13
For x rounds, cost for child:
= 3x + 10
2x + 13 = 3x + 10
x = 3
Thus, for 3 rounds of bingo, the costs will be the same for an adult and a child option second is correct.

You've sold 101 rooms, 98 rooms, and 102 rooms over the past 3 days. You have 116 rooms available. What is your average occupancy for the past three nights?
Answer:
The average occupancy rate for the past three nights is of 86.49%.
Step-by-step explanation:
We want to find the average occupancy rate, as a percentage.
You've sold 101 rooms, 98 rooms, and 102 rooms over the past 3 days.
So the mean number of rooms sold during the past 3 days is given by:
[tex]A = \frac{101 + 98 + 102}{3} = \frac{301}{3} = 100.33[/tex]
Average rate:
[tex]R = \frac{100.33*100}{116} = 86.49[/tex]
The average occupancy rate for the past three nights is of 86.49%.

The answer is that Topsoil costs 10$ more than mulch.
When we look at the equation y=20x, we see that for one cubic yard, it costs 20$. when we look at the graph, we see that for one cubic yard it costs 30$ for topsoil, therefore, Topsoil is $10 more than mulch for each cubic yard.

Find all zeros of f(x) = x4 + 5x2 – 36 by completely factoring the polynomial.
f(x) = x4 + 5x2 – 36 = (x2 – 4) (x2 + 9) =
List the four zeros of the function.
Real zeros: +
Complex zeros:
Answer:
Real Zeros x = ±4
Complex zeros : x = ±3 i
Step-by-step explanation:
Explanation
f(x) = x⁴ + 5x² – 36
f(x) = x⁴ + 5x² – 36
= (x²)² + 9 x² - 4 x² - 36
= x² (x² + 9) - 4( x² +9)
= (x² -4 ) (x² +9)
f(x) = x⁴ + 5x² – 36 = (x² -4 ) (x² +9)
(x² -4 ) (x² +9) = 0
⇒ x² -4 = 0 and x² +9 =0
⇒ x² -2² = 0 and x² = -9
⇒ x = ±4 and x = ±3 i
Real Zeros x = ±4
Complex zeros : x = ±3 i
I need help I don’t understand this
Answer:
Step-by-step explanation:
lets say "a" for the empty line,
for small triangle; y^2 = 2^2 + x^2
right triangle; we say a for empty line, a^2= 6^2 + x^2
and big triangle covering both triangles, 8^2 = y^2 + a^2
lets add left sides and right sides in each;
x^2 + 4 + x^2 + 36 + y^2 + a^2 = y^2 + a^2 + 64 and we can delete same things for both sides
y^2 and a^2 can be deleted and 4+36 - 64
2(x^2)=24
x^2= 12
and x will be √12
so, y^2 = x^2 + 2^2 which means y^2 = 12+4 y=16

Find the missing side of the triangle leave answer in simplist radical form
Answer: x = 3 √21
Step-by-step explanation:
you gotta use our good, old, trusty friend pythagorean theorem.
a^2 + b^2 = c^2
x^2 + 6^2 = 15^2
x^2 = 15^2 - 6^2
x^2 = 189
x = √189
x = √27 · 7
x = 3 √3 · 7
x = 3 √21
What is the value of x in x + 129 = 237?
Answer:
108
Step-by-step explanation:
237-129= 108
hope it helps
Answer:
x= 108
Step-by-step explanation:
use inverse operations to subtract 129 from both sides
x+129=237
-129 -129
x=108

Annie and Emily are sisters. Emily’s age is 7 more than twice Annie's age, a. The sum of their ages is 45. Which equation represents this relationship?
Answer:
3x=38
Step-by-step explanation:
Given that,
Annie and Emily are sisters. Emily’s age is 7 more than twice Annie's age, a. The sum of their ages is 45.
Let Annie's age is x.
Emily's age = 7+2x
ATQ,
The sum of their ages is 45.
x+7+2x = 45
Taking like terms together,
x+2x = 45-7
3x=38
Hence, this is the relation between their ages.
