Answer:
[tex] \huge \purple{\therefore \cos2a} \orange{= }\red{\frac{7}{25} } [/tex]
Step-by-step explanation:
[tex] \because \cos2a =1 - 2 { \sin}^{2} a \\ \\ \therefore \cos2a =1 - 2 \bigg( { \frac{3}{5} }\bigg) ^{2} \\ \\\therefore \cos2a =1 - 2 \times \frac{9}{25} \\ \\\therefore \cos2a =1 - \frac{18}{25} \\ \\\therefore \cos2a = \frac{25 - 18}{25} \\ \\ \huge \purple{\therefore \cos2a} \orange{= }\red{\frac{7}{25} } \\ \\[/tex]
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

Zack wants to purchase vinyl to go on his bathroom floor. The vinyl is sold by the foot in length. If the area of his bathroom is 100 square feet, what will one side of the square bathroom measure?
Answer:
x = 10 feet
Step-by-step explanation:
Given that,
The area of his bathroom is 100 square feet.
We need to find the one side of the square bathroom.
Let the side be x. The area of a square is given by :
[tex]A=x^2\\\\100=x^2\\\\x=10\ \text{feet}[/tex]
So, the side of the square bathroom is 10 feet.

−56e−23e=−24
Answer: at end of explanation
Step-by-step explanation:
First simply operate the e's, so get common factor and (- 56 - 23)e = -24. This leaves you with -79e = -24. Then move the number multiplying e to dividing the other side, so e = -24 / -79, wich results in 0.8 period. So your result rounded to 2 decimal places is 0.89.
Answer:
0.304
Step-by-step explanation:
Step by Step Solution:
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-56*e-23*e-(-24)=0
Step by step solution :
STEP
1
:
Solving a Single Variable Equation
1.1 Solve : -79e+24 = 0
Subtract 24 from both sides of the equation :
-79e = -24
Multiply both sides of the equation by (-1) : 79e = 24
Divide both sides of the equation by 79:
e = 24/79 = 0.304

22. Determine the value of c so that the line
segment with endpoints B(2, 2) and C(9,6)
BC
is parallel to the line segment with endpoints
D(c, -7) and E(5, -3).
help is appreciated !!!
Answer:
If the lines BC and DE are parallel, the value of c is c=-2
Step-by-step explanation:
We are given line segment BC with end points B(2, 2) and C(9,6) and line segment DE with endpoints D(c, -7) and E(5, -3).
Using slope formula: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex] we can find point c
When 2 lines are parallel there slope is same.
So, Slope of line BC =Slope of Line DE
[tex]\frac{y_2-y_1}{x_2-x_1}=\frac{y_2-y_1}{x_2-x_1}[/tex]
We have:
[tex]x_1=2, y_1=2, x_2=9, y_2=6 \ for \ line \ BC \ and \\\x_1=c, y_1=-7, x_2=5, y_2=-3 \ for \ line \ DE \[/tex]
Putting values and finding c
[tex]\frac{6-2}{9-2}=\frac{-3-(-7)}{5-c}\\ \frac{4}{7}=\frac{-3+7}{5-c} \\ \frac{4}{7}=\frac{4}{5-c} \\Cross \ multiply:\\4(5-c)=4*7\\20-4c=28\\-4c=28-20\\-4c=8\\c=\frac{8}{-4}\\c=-2[/tex]
So, If the lines BC and DE are parallel, the value of c is c=-2
Round 59..166 to the nearest tenth
Answer:
59.2
Step-by-step explanation:
so each number placement after the decimal is different.
it goes tenths place, hundredths place, thousandths place, ten thousandths place and so forth
Answer:
59.2
Step-by-step explanation:
the tenth place is the 1st place on the right side of the dwecimal. so this rounded to the nearest tenth woul be 59.2, since 6 is enough to make 1 round up one more
Explain why the exponents cannot be added in the product 12^3 x 11^3?? I need a simple answer that won’t be confusing pls.
Answer:
The bases aren't the same
Step-by-step explanation:
If the bases are the same, then their exponents are added. In this case, since the exponents are the same, then 12^3*11^3=(12*11)^3=132^3=2299968
Last year, Lashonda opened an investment account with $7200 . At the end of the year, the amount in the account had decreased by 24.5% .How much is this decrease in dollars? How much money was in her account at the end of last year?
Answer:
1. $17642. $5436Step-by-step explanation:
Step one:
given data
Initial account balance= $7200
we are told that the decrease was by 24.5%
Step two:
1. How much is this decrease in dollars?
let us solve for 24.5% of $7200
=24.5/100*7200
=0.245*7200
=1764
the decrease is $1764
2. How much money was in her account at the end of last year?
the final account balance is
=7200-1764
=$5436
What is the midpoint of the line segment that has endpoints (3,8) and (1,−4) ?
Answer:
D
Step-by-step explanation:
Midpoint Formula:
[tex]\frac{x_{1}+x_{2}}{2}, \frac{y_{1}+y_{2}}{2}[/tex]
[tex]\frac{3+1}{2}[/tex] ⇒ [tex]\frac{4}{2}[/tex] ⇒ [tex]2[/tex]
[tex]\frac{8+-4}{2}[/tex] ⇒ [tex]\frac{8-4}{2}[/tex] ⇒ [tex]\frac{4}{2}[/tex] ⇒[tex]2[/tex]

Morgan is in the business of manufacturing phones. She pays a cost of $200
per phone produced for materials and labor and also must pay a daily fixed
cost of $400 to rent the building and equipment. Make a table of values and
then write an equation for C, in terms of p, representing total cost, in dollars,
of producing p phones in a given day.
Answer:
C = 200p + 400
Step-by-step explanation:
Because C is the cost of a given day, 400 acts as a y-intercept.
400 is the initial fee paid then 200 per each phone manifactured, meaning that 200 is the slope.

Avery owns a small business selling ice-cream. She knows that in the last week 6
customers paid cash, 48 customers used a debit card, and 16 customers used a credit
card.
If next week, she is expecting 400 customers, about how many would you expect to
pay with a credit card? Round your answer to the nearest whole number.
Answer:
About 91 customers would be expected to pay with a credit card.
Step-by-step explanation:
Well you have ro set up a ratio of 16/70 = x/400
This way the amount of people that used a credit card out of all of the people that came and you can figure out the amount of people that will use a credit card out of the 400 people that are expected tho come. You multiply like a butterfly. 70 times x and 400 by 16. Then you will get 6,400=70x divide both sides by 70 and get 91.42=x so if ypu round, 91 people are expected to pay using a credit card out of the 400 customers that are expected to come.

A) -42.258
B) 52.942

According to a survey conducted by the Texas Free Press, 125 out of 500 people do not have internet access at their homes. What percent of the people surveyed do have internet access at their homes?
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
