Step-by-step explanation:
1. For a one-tailed test (lower tail) at 93.7% confidence, Z =
2. For a one-tailed test (upper tail), a sample size of 24 at 90% confidence, t =
3. In a one-tailed hypothesis test (lower tail=left tailed test) and where the population standard deviation is known, the test statistic is determined to be -2.5. What is the p-value for this test?
Answer:
1) Z = -1.8592
2) t = 1.7139
3) p = 0.0062
Step-by-step explanation:
1) Area: (93.7+100)/2 = 193.7/2 = 96.85
Z = invNorm(0.9685,0,1) = 1.8592, but since the test is one-tailed at the lower tail, Z is actually -1.8592
2) Area: (90+100)/2 = 190/2= 95 where df=n-1=24-1=23
t = invT(0.95,23) = 1.7139
3) Since the population standard deviation is known, our test statistic is z=-2.5, making the p-value for the test p=normalcdf(-1e99,-2.5,0,1) = 0.0062
If a 5-foot tall man casts a shadow of 12 feet when standing on level ground, then the distance from the top of his head to the tip of his shadow is
Answer:
13 feet
Step-by-step explanation:
you can use the Pythagorean Theorem to solve this problem because the man standing on the ground forms a 90 degree angle
5² + 12² = c²
25 + 144 = c²
169 = c²
c = √169 which is 13
a car travels 156 miles in 3 hours and 15 minutes. how many miles does it travel per hour
Answer:
48 mph
Step-by-step explanation:
Convert 3 hours 15 minutes to hours.
15 minutes = 15/60 hour = 1/4
So 3 hours 15 mins = 3 1/4 hours = 13/4 hours
156 miles in 13/4 hours ==> speed = 156 ÷ 13/4 = 156 x 4/13 = 48
On Marlene's trip to Starved Rock, her average rate of speed for the entire five-hour trip was 62 miles per hour. For the first two hour of her trip, she kept her average speed at 50 miles per hour. Then she realized she was going to be late to meet her friend for dinner, so she started driving faster. What was her average speed for the last three hours of the trip?

The sum of 8 and Jose's savings is 50.
Answer:
8 + x = 50, so Jose's saving or x = 42
Hope this helps!
Answer:
The equation is: s + 8 = 50
The amount of Jose's savings is: 42
Step-by-step explanation:
Let s = Jose's savings.
s + 8 = 50
Subtract 8 from both sides.
s = 42
The equation is: s + 8 = 50
The amount of Jose's savings is: 42

How do you write an equation of a line that passes through (4,3) and has a slope of 2?
Answer:
y = 2x - 5
Step-by-step explanation:
y-intercept form is y = mx + b, where m is the slope and b is the y-intercept. We know the slope is 2, so all that's left is to find the y-intercept. To do this, for every 1 we subtract from x in (4,3), we take away 2 from y because the slope is two. We keep doing this until x is zero. The remaining y-value is the y-intercept.
Answer:
[tex]y = 2x-5[/tex], see below.
Step-by-step explanation:
There is enough information to make a point slope equation that we can later convert into slope intercept.
Point slope form is:
[tex]y-y_1=m(x-x_1)[/tex]
[tex](x_1,y_1): \text{A point.} \\\\m - \text{Slope.}[/tex]
We are given the slope of 2 and the point (4,3).
Replace the variables with the given information.
[tex]y-y_1=m(x-x_1)\rightarrow y-3=2(x-4)[/tex]
With the equation we will now convert it into slope intercept form:
[tex]y-3=2(x-4)\\\\y-3=2x-8\\\\y-3+3=2x-8+3\\\\\boxed{y=2x-5}[/tex]
Hope this helps!

Answer:
D. (x+6)²+(y+1)²=16
Step-by-step explanation:
The equation for a circle in standard form is (x-h)²+(y-k)²=r², where (h,k) is the centre of the circle and r is the radius.
We can read from the graph that the centre is (-6,-1) and the radius is 4. Sub these in:
(x-h)²+(y-k)²=r²
(x-(-6))²+(y-(-1))²=4²
(x+6)²+(y+1)²=16

There are 750 people at a football game Out of this number 320 are students what percent of people at the football game are not students? Round to the nearest hundredth,if needed.
The percent of people at the football game are not students will be 57.33%.
What is mean by Percentage?
A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
The number of peoples in football game = 750
The number of students = 320
Now.
Find the percent of people at the football game are not students as;
Number of people are not students = 750 - 320
= 430
Thus, The percent of people at the football game are not students is;
Percent = 430 / 750 x 100
= 0.5733 x 100
= 57.33%
Hence, The percent of people at the football game are not students will be 57.33%.

The plane region is revolved completely about the x-axis. Find its surface area in EXACT form (in terms of pi and/or with simplified radicals as necessary).
Answer: The Given plane region is missing attached below is the plane region
answer : 24 π or 75.40 sq. units
Step-by-step explanation:
Given data :
Height of plane region = 3
base of plane region = 4
When we revolved the plane region completely we will we forming a cone hence we will calculate for the surface area of a cone
Radius of the new cone = 3
Height of the cone = 4
slant height of the cone ( l ) = [tex]\sqrt{4^2 +3^2}[/tex] = 5
surface area of cone = πr^2 + πrl
= π ( 3 )^2 + π (3 ) ( 5 )
= 24 π or 75.40 sq. units
