Answer:

7 degrees

Step-by-step explanation:

It has a right angle and it's a triangle so the angle is a complementary angle so the total for the angle is 90 degrees.

So then you add 39 + 44 and get 83

So, 90 - 83 +7

So your total is 7 degrees

Answer:

The third choice 2(a^3+3a^2h+3ah^2+h^3)

Step-by-step explanation:

f(a+h)=2(a+h)^3

Ok ill answer the question but do you want me to evaluate it or find it to the simplest form ?

This question is incomplete, the complete question is;

Suppose that a random sample of eighteen recently sold houses in a certain city has a mean sales price of $280,000, with a standard deviation of $10,000. Under the assumption that house prices are normally distributed, find a 95% confidence interval for the mean sales price of all houses in this community. Then find the lower limit and upper limit of the confidence interval.

Answer:

At 95%, confidence interval is ( 275026.7, 284973.3 )

Hence;

Lower limit = 275026.7

Upper limit = 284973.3

Step-by-step explanation:

 Given that;

mean x = $280,000

standard deviation σ = $10,000

sample size n = 18

degree of freedom df = n - 1 = 18 - 1 = 17

∝ = 1 - 95% = 1 - 0.95 = 0.05  

so

Critical t value = tinv( 0.05, 17 ) = 2.11

now, at 95% confidence interval for mean will be;

⇒ x ± [ Critical t value × ( σ/√n) ]

so we substitute

⇒ 280,000 ± [  2.11 × ( 10000/√18) ]

⇒ 280,000 ± [  2.11 × 2357.0226 ]

⇒ 280,000 ± 4973.3

⇒ 280000 - 4973.3, 280000 + 4973.3

At 95%, confidence interval is ( 275026.7, 284973.3 )

Hence;

Lower limit = 275026.7

Upper limit = 284973.3

Sorry that it is in english.

Step-by-step explanation:

The arms of the compass mesure the radius.

[tex]r=10\\2r=diamater (d)\\2*10=d\\20=d[/tex]

Answer:

18 $1 bills and 11 $5 bills.

Step-by-step explanation:

First, we use the guess-and-check method.

$5X29=$145

Then, $5-$1=$4.

$145-$73=$72

$72 divided by 4 is 18.

29-11=18

11x$5=$55

$1x18=$18

$55+18=73.

Answer:

The answer will be 7(2x - 1)

Step-by-step explanation:

1) Convert 7 and 1/2 to improper fraction. Use this rule: a b/c = ac + b/c

[tex]7x + \frac{1}{2} + 7x - \frac{7 \times 2 + 1}{2} [/tex]

2) Simplify 7 × 2 to 14 .

[tex]7x + \frac{1}{2} + 7x - \frac{14 + 1}{2} [/tex]

3) Simplify 14 + 1 to 15.

[tex]7x + \frac{1}{2} + 7x - \frac{15}{2} [/tex]

4) Collect like terms.

[tex](7x + 7x) + ( \frac{1}{2} - \frac{15}{2} )[/tex]

5) simplify.

[tex]14x - 7[/tex]

6) Factor out the common term 7.

[tex]7(2x - 1)[/tex]

Therefor, the answer is 7( 2x - 1 ).

Answer:

ŷ = 1.85057X1 + 0.9688X2 + 84.77516

Step-by-step explanation:

Given the data:

Weekly Gross Revenue (Y) :

97

90

96

93

95

95

94

94

Television Advertising (X1) :

2.5

The regression equation obtained using a multiple regression calculator is :

ŷ = 1.85057X1 + 0.9688X2 + 84.77516

x1 and x2 are the predictor variables

y is the predicted variable (Weekly Gross Revenue).

Slope x1 = 1.85057

Slope x2 = 0.9688

Intercept = 84.77516

Answer:

I think it is 10:17 the ratio

Answer:

m - n = 501

Step-by-step explanation:

Remark

The first thing you have to do is find the number of odd and even numbers. This is where you have to be careful because there is a danger of being out by one.

equation

l = a + (n - 1)*d

Solution even

l = 1000

a = 2

d = 2

1000 = 2 + (n - 1)*2

998/2 = (n - 1) * 2 / 2

499 =  n - 1

n = 500

Solution odd

l = 1001

a = 1

d = 2

1001 = 1 + (n - 1)*2

1000 =  (n - 1)*2

1000/2 =  (n - 1)2/2

500 =  n - 1

501 = n

Sum Even of even numbers from 1 to 1001

Givens

a = 2

n = 500

l = 1000

Equation

Sum = (a + l ) * n / 2

Solution

Sum = (2 + 1000)*500/2

Sum = 1002 * 250

Sum = 250500

Sum of Odd numbers from 1 to 1001

a = 1

l = 1001

n = 501

Equation

sum = (a + l)*n/2

sum = (1 + 1001) * 501

sum = (1002)*501 / 2

Sum =  251001

Answer

m - n = 251001 - 250500 = 501

Step-by-step explanation:

Total Shares = 3 + 4 + 5 = 12 shares

12 Shares = R600

(12÷12) Share = R(600÷12)

1 Share = R50

(1×3) Shares = R(50×3)

3 Shares = R150

4 Shares = R(50×4) = R200

5 Shares = R(50×5) = R250

Tom Gets R150.

Paul gets R200.

Anne gets R250.

Answer:

234

Step-by-step explanation:

Answer:

3.79 centimetres

Step-by-step explanation:

1 day = 24 hours

91 ÷ 24 = 3.79 centimetres

Answer:

if the question you're asking is how many cm does bamboo grow per hour, then around 3.81 cm per hour.

Step-by-step explanation:

Let h be the number of hours.

Total Cost = Fixed Costs + Variable Cost

= Initial Fee + Hourly Charge

= 75 + 9h

Given,

[tex]75 + 9h = 250 \\ 9h = 250 - 75 \\ 9h = 175 \\ h = 175 \div 9 \\ = 19 \frac{4}{9} hr[/tex]

Since the car cannot be rent part of an hour, the highest possible whole number is 19 hours.

Step-by-step explanation:

I took the test on T4L and got it right.

Answer:

11.53 degrees.

Step-by-step explanation:

ok so we know the hyp and opp sides. this means that it is sin. according to SOHCAHTOA we do sin^-1(2/10). you should get 11.53

Answer:

11.5396°

Step-by-step explanation:

Please see the attached image

We can do sin(x)=2/10, which simplifies to sin(x)=1/5

To get x by itself do [tex]x=sin^{-1}[/tex](1/5) which ≈11.5396°
