P>.9 and it is found the statistic is 1.04 Test the claim with 5% significance level. is the test left right or two tailed and what is the p value
Complete Question
The alternative hypothesis is [tex]H_a : p > 0.9[/tex] and it is found the statistic is 1.04 Test the claim with 5% significance level. is the test left right or two tailed and what is the p value
Answer:
This a right tailed test
The p-value is p-value = 0.14917
Step-by-step explanation:
From the question we are told that
The alternative hypothesis is [tex]H_a : p > 0.9[/tex]
The test statistics is [tex]z = 1.04[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
Generally this a right tailed test because from the alternative hypothesis p > 0.9 i.e due to the greater than sign signifying that test will be focusing on the right tail of the normal curve
From the z table the area under the normal curve to the right corresponding to 1.04 is
P( Z> 1.04 ) = 0.14917
Generally the p-value is mathematically represented as
p-value = P( Z> 1.04 ) = 0.14917

Leo took an Uber to get to football practice. Uber charged $1.25 per mile (m) and he gave the driver a $5.00 tip. If the total trip was $16.25, how many miles did he travel to football practice?
Answer:
9milesStep-by-step explanation:
Step one:
given data
we are told that the uber charges $1.25 per mile
and that Leo also gave a tip of $5
the function for the total charge is given as
y=mx+c
Step two:
we will use the notation m for the number of miles traveled
given that the total trip is $16.25
16.25=1.25m+5
solving for m we have
16.25-5=1.25m
11.25=1.25m
divide both sides by 1.25
m=11.25/1.25
m=9
So he travelled 9miles
Question 1
Which of the following statements is NOT true?
Answer:
the bottom one
Step-by-step explanation:
They are both the same ab and bc but im not entirely sure
Because AB, AC, and BC describe the same line, we conclude that the last option is the false one.
Which of the statements is not true?On the graph, we can see a line that contains points A, B, and C.
Now we want to see which statement is false.
Now, because A, B, and C are on the same line, is trivial that:
AB, AC, and BC (these 3 lines) have the same slope, because these are 3 different names for the exact same line.
Then we can conclude that the incorrect statement is the last one.

Answer:
Step-by-step explanation:
Take 125 and divide by 500 this equals 0.25 or 25%
Answer:
x=25
Step-by-step explanation:
[tex]\frac{125}{500} *\frac{x}{100}[/tex] this is just a typical percent equation
[tex]12500=500x[/tex] cross multiply
x=25 divide by 500 to get the answer
Write an absolute value inequality to represent each situation.
Two friends are hiking in Death Valley National Park. Their elevation ranges
from 228 ft below sea level at Badwater to 690 ft above sea level at Zabriskie
Point. Let x represent their elevation in feet.
Answer:
║ x - 231 ║ ≤ 459
Step-by-step explanation:
Since we have 228 ft below sea level, this is x' = -228 ft. Also, we have 690 ft above sea level, this is x" = 690 ft.
Since x is our elevation in feet, x ranges from -228 ≤ x ≤ 690.
To write an absolute value equation for x, we first take the average of the two values for the ranges to obtain the ideal value of x.
So, ideal value = [690 + (-228)]/2 = 462/2 = 231.
We also find the tolerance by taking the difference of both values and dividing by 2. So tolerance = [690 - (-228)]/2 = [690 + 228)]/2 = 918/2 = 459.
Subtracting 231 from each value of the inequality we have
-228 - 231 ≤ x - 231 ≤ 690 - 231
-459 ≤ x - 231 ≤ 459
Since we have in magnitude the values on the left and right side of the inequality,
So ║ x - 231 ║ ≤ 459
what is the slope of the line, (-6, -8) and (2, 8)?
Answer:
Your slope would be 2.
Step-by-step explanation:
To find the slope, you would need to use the formula: y2-y1/x2-x1
In this case, the equation would be 8-(-8)/2-(-6)
8 - (-8) = 16
2 - (-6) = 8
16/8 = 2
Slope: 2
I don't understand proportional relationship can u help?
Answer: I’ll explain it in simpler terms for you. A proportional relationship is one in which two quantities vary directly with each other. Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional. An example of a proportional relationship is simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error. Hope this helps! :D
Justin wants to make a necklace with 72 beads. He knows that 12 beads
take up 4 inches of string, but the store only sells string by the centimeter.
How many centimeters should he buy? Explain. (Hint: 1inch = 2.54 cm) *
Answer:
60.96cm
Step-by-step explanation:
So if 12 beads=4 inches
72 beads=72 beads*4 inch
12 beads
That will give you 24inches. inch-cm multiply by 2.54cm
=60.96cm of rope
The sum of two numbers a and b is 7 and the difference between them is 2. What is the value of a x b ? Give your answer as a mixed number in its simplest form.
Answer:
45/4
Step-by-step explanation:
We can interpret the question to have two equation which can be solve simultaneously
a+b=7------------(1)
a-b=2------------(2)
From eqn(2) make a subject of formula
a=2+b--------(3)
Substitute the (3) into eqn(1)
a+b=7------------(1)
2+b+b=7
2b=7-2
2b=5
b=5/2
From equation (3) substitute value of b to find a
a=2+b--------(3)
a= 2+5/2
a=9/2
Then What is the value of a x b ?
9/2× 5/2
=45/4
Answer:
11 1/4
Step-by-step explanation:
a+b=7
a-b=2
adding equations gives us 2a=9 so a= 9/2
b= 7- 9/2= 14-9/2=5/2
therefore a x b= 9/2 x 5/2 =45/4
45/4 in a mixed number is 11 1/4

Write an equation of the line passing through the point (6, 3) that is perpendicular to the line 6x + 5y = 10
An equation of the line is
y=?
Answer:
[tex]y=\frac{5}{6}x-2[/tex]
Step-by-step explanation:
Let the equation of a line passing through a point [tex](x_1,y_1)[/tex] and slope [tex]m_1[/tex] is,
[tex]y-y_1=m_1(x-x_1)[/tex]
Equation of the second line has been given as,
6x + 5y = 10
Slope-intercept form of the equation will be,
5y = -6x + 10
y = [tex]-\frac{6}{5}x+10[/tex]
Here slope of the line [tex]m_2=-\frac{6}{5}[/tex]
If both the lines are perpendicular,
By the property of perpendicular lines,
[tex]m_1\times m_2=-1[/tex]
[tex]m_1\times (-\frac{6}{5})=-1[/tex]
[tex]m_1=\frac{5}{6}[/tex]
Therefore, equation of the line passing through (6, 3) and slope = [tex]\frac{5}{6}[/tex] will be,
y - 3 = [tex]\frac{5}{6}(x-6)[/tex]
y = [tex]\frac{5}{6}x-5+3[/tex]
[tex]y=\frac{5}{6}x-2[/tex]

hot air balloon is attached to the ground by a cable that is 200 meters long. The cable makes a 57° angle with the ground.
How many meters above the ground is the balloon if there is no slack in the cable? Round your answer to the nearest tenth of a meter
Answer:
Let C be the position of the meteorological station, B the position of the balloon and CB be the cable.
Let the height of the balloon from the ground be AB=hmetres.
In a right angled triangle ACB

∴h=100×1.732=173.2 since

=1.732
Hence, the height of the balloon above the ground is 173.2m
By inscribing the given information in a right triangle, we will see that the ballon is 167.7 meters above the ground.
Think in the situation as in a right triangle, you have a hypotenuse that is equal to the length of the cable, you know one angle of 57°, and the opposite cathetus to this angle represents the height at which the ballon is, this is what we want to find.
Using the relation:
sin(θ) = (opposite cathetus)/hypotenuse.
Where:
θ = 47°hypotenuse = 200mopposite cathetus = height.Replacing that we get:
sin(57°) = height/200m
sin(57°)*200m = height = 167.7m
So the balloon is 167.7 meters above the ground.
