Answer: x = 39°, y = 5

Step-by-step explanation:

∠ADB and ∠CDB are same which means it's 90 degrees

and the triangle is isosceles, so ∠A=∠X and ∠ABD=∠CBD

180= ∠A + ∠B + ∠D

180= 51 + 90 + ∠D

∠D = 39 = x

for y I told you this is the isosceles triangle

so , AD = DC

Answer: [tex]\dfrac{665}{1496}[/tex]

Step-by-step explanation:

Given : In a group , there are 20 boys and 14 girls.

Total people = 20+14=34

Number of ways to choose 3 people out of 34 = [tex]^{34}C_3[/tex]

Number of ways to choose  1 girl and 2 boys = [tex]^{14}C_1\times^{20}C_2[/tex]

The  probability that 1 girl and 2 boys are selected = [tex]\dfrac{^{14}C_1\times ^{20}C_2}{^{34}C_3}[/tex]

[tex]\dfrac{14\times\dfrac{20!}{2!18!}}{\dfrac{34!}{3!31!}}\ \ \ [^nC_r=\dfrac{n!}{r!(n-r)!}]\\\\=\dfrac{14\times\dfrac{20\times19}{2}}{\dfrac{34\times33\times32\times31!}{3\times2\tims3!}}\\\\=\dfrac{665}{1496}[/tex]

Hence, required probability = [tex]\dfrac{665}{1496}[/tex]

Answer:

y = 2/3 x + 1/3

Step-by-step explanation:

First find the slope of the given line by solving for "y":

3 x + 2 y = -7

2 y = - 3 x - 7

y = - 3/2 x - 7/2

which shows a slope of "- (3/2)"

Then, the slope of a line perpendicular to it must be "the opposite of the reciprocal" of this slope, that is: "2/3"

We use this info and the requested point (1, 1) to find the complete equation of the perpendicular line:

y = 2/3  x + b

1 = 2/3 (1) + b

1 - 2/3 = b

b = 1/3

Then the equation of the line is:

y = 2/3 x + 1/3

which agrees with the third answer shown in the list of options.

Answer:  Is this linear regression equation a good fit for the data? Why or why not? A. r = - .7622 , so this is a good negative correlation fit for the data . B. r = - .9919 , so this is a very good negative correlation fit for the data C. r = .9919 , so this is a very good positive correlation fit for the data . D. r = .7622 so this is a good positive correlation fit for the data .

Answer:

1 1/4 cup left

Step-by-step explanation:

.75 of a third is a fourth, so that would mean that 2/3 is .50, 75% of 2/3, is 0.50, 1/4 is 0.25, so that would mean .75, which is 3/4 cups, so that would mean he needs 1 3/4 cups, so he has 1 1/4 cup left

Answer: the probability that Kevin will win the spring break cruise to the Caribbean is 0.01559

Step-by-step explanation:

Given that;

the total number of raffle ticket sold by the student is 2629

Kevin bought 41 tickets

the probability that Kevin will win the spring break cruise to the Caribbean?

The required probability will be:

Probability

=(Number of favorable outcomes for an Event) / (Total Number of outcome)

so

probability = 41 / 2629

= 0.01559

Therefore the probability that Kevin will win the spring break cruise to the Caribbean is 0.01559

Answer:

968 - 744 = 224

Step-by-step explanation:

if Fatima's lettuce broccoli and peas all weigh 968 grams when weighed together and her lettuce and broccoli way 744 grams, as shown in the photo, when weighed together you would subtract the weight of the lettuce and broccoli from the weight of the peas, lettuce, and broccoli together.

you would then get 224 as your answer. your number sentence then should be:

968 - 744 = 224

Step-by-step explanation: 968-744=224 is the answer

Answer subtract 744 and 968 and you will get the answer

Let s be the speed of the person's kayak in still water.

Given, speed of current = 2 mph

Upstream distance = 9 miles

Speed of the person upstream = s-2

Time traveled upstream = 9/s-2

Downstream distance = 13 miles

Speed of the person downstream = s+2

Time traveled downstream = 13/s+2

Given,

9/s-2 = 13/s+2

Cross-multiplying,

9*(s+2) = 13*(s-2)

9s + 18 = 13s - 26

Grouping like terms together,

13s-9s = 26+18

4s = 44

s = 11 mph

Speed of person's kayak in still water = 11 mph

Answer

2/5

Step-by-step explanation:

if you multiply each fractions numerator and denominator so that they can be in the same group you will get

2/5=8/20

1/4=5/20

therefore 2/5 is bigger.

^^ i hope that made sense :)

The solution is: 2/5 is the fraction which fraction is larger than 1/4.

Here, we have,

given that, the fractions are, 2/5 & 1/4 ,

if we multiply each fractions numerator and denominator so that they can be in the same group.

here, we have to multiply 1st fraction by 4 both and 2nd fraction by 5 both.

we will get:

2/5=8/20

1/4=5/20

now, we know that,

8 > 5

=> 8/20 > 5/20

=> 2/5 > 1/4

therefore 2/5 is bigger.

Hence, The solution is: 2/5 is the fraction which fraction is larger than 1/4.

Answer:

D is correct

Step-by-step explanation:

I got it right on my edge math unit test review.

The value of |c| = 9√2 and θ = 225⁰

The magnitude or size of a mathematical object is a property which determines whether the object is larger or smaller than other objects of the same kind.

Here, given values;

a = (-7, 3)  and b = (-2, -12)

Now, c = a + b

        c = (-7, 3) + (-2, -12)

        c = (-9, -9)

Now, |c| = √(9²+9²)

         |c| = 9√2

Now, tan θ = |y/x|

        tan θ = |-9/-9|

       tan θ = 1

       tan θ = tan 225⁰

         θ = 225⁰

Thus, the value of |c| = 9√2 and θ = 225⁰

Answer:

-1, 1, 5

Step-by-step explanation:

Factor by grouping:

Factor out x² from the first two terms:

f(x) = x³ - 5x² - x + 5

f(x) = x²(x - 5) - x + 5

Factor out -1 from the last two terms:

f(x) = x²(x - 5) -1(x - 5)

Then, put the two terms together:

f(x) = (x² - 1)(x - 5)

(x² - 1) is a difference of squares that can be factored further:

f(x) = (x + 1)(x - 1)(x - 5)

Set this equal to 0, and set each factor equal to zero. Then, solve for x:

x + 1 = 0

x = -1

x - 1 = 0

x = 1

x - 5 = 0

x = 5

So, the zeroes are -1, 1, and 5

Answer:

The warranty the company should use is of 57,520 mile.

Step-by-step explanation:

Let X denote the tread life of a particular brand of tire.

It is provided that,  [tex]X\sim N(60,000, 1600^{2})[/tex].

Also provided that the company wants 94% of the tires to outlast the warranty.

Let x denote the warranty .

That is, P (X > x) = 0.94.

⇒ P (X < x) = 0.06

⇒ P (Z < z) = 0.06

The corresponding value of z is -1.55.

*Use a z-table.

Compute the value of x as follows:

[tex]z=\frac{X-\mu}{\sigma}\\\\-1.55=\frac{x-60000}{1600}\\\\x=60000-(1.55\times 1600)\\\\x=57520[/tex]

Thus, the warranty the company should use is of 57,520 mile.

Answer:

A) $32,000 B) $37,500 C) $5,500

Step-by-step explanation:

Price of jeep: $37,000

Michael uses $5,000 of his own money toward that total $37,000-$5,000= $32,000

Monthly payments $625.00×60months=$37,500

After paying $5,000 of his own money, & bringing theamount owed to $32,000. Michael still has to pay back $37,500. Making, the finance chardge $5,500. ($37,500-$32,000= $5,500)

Amount financed =  $32000, total amount of monthly payment = $37500 and total amount of the finance charge = $5500.

"Dealer financing is a type of loan that is originated by a retailer to its customers and then sold to a bank or other third-party financial institution. The bank purchases these loans at a discount and then collects principle and interest payments from the borrower. This is also called an indirect loan."

According to the question,

Given,

Price of jeep = $37000

Down payment = $5000

Total number of monthly payment = 60

Amount to be paid after down payment

= $37000 - $5000

= $32000                                                  ____( 1 )

Amount paid in Monthly payments = $625.00 × 60months

                                                          = $37500          ____( 2 )

From ( 1 ) and ( 2 ) we get,

Finance charge amount = Total monthly amount - Total amount financed

                                        = $37500 - $32000                                    

                                        = $5500

Hence, amount financed , total amount monthly payment and total amount of the finance charge is $32000 , $37500 and $5500.

Answer:

Add both of the function together.

Step-by-step explanation:

s(x) + a(x) = 450 + 6(x - 2)

Answer:

1) The function that represents how the money in her suit case is s(x) = 450

The function that represents the amount she is able to make from baby sitting is a(x) = 6(x - 2)

Given that the values of the two function are the same units, dollars, and the amount are to be put to the same use for spending money for her first year of college, the combination of the two functions is the sum of their values given as follows;

f(x) = s(x) + a(x) = 450 + 6(x - 2)

2) For simplification, we expand the second term and add the constant terms as follows;

f(x) = 450 + 6·x - 12

f(x) = 450 + 6·x - 12

f(x) = 438 + 6·x

The sum of the two terms becomes, f(x) = 438 + 6·x
