In square ABCD, diagonals AC and DB intersect at point E, m∠EBC=(3x+9y)°, and m∠EAB=(5x+5y)°.

telo118 [61]

Answer:

Step-by-step explanation:

m∠EBC = 45°

3x + 9y = 45

Divide the entire equation by 3

x + 3y = 15 --------------------(I)

m∠EAB = 45

5x + 5y = 45

Divide the entire equation by 5

x +y = 9 -------------(II)

Multiply equation (II) by (-1)

(I) x + 3y = 15

(II)*(-1) <u> - x - y = -9</u> {Now add}

2y = 6

y = 6/2

y = 3

Plugin y = 3 in equation (I)

x + 3*3 = 15

x + 9 = 15

x = 15 - 9

x = 6

Langston estimated the temperature to be 45°F . The thermometer showed the actual temperature to be 50°F. Complete the steps bel

The percentage error is 11.1%

<h3>What is percentage error?</h3>

Percentage error is simply the difference between the exact and the estimated values as a percentage

The given parameters are:

Estimate = 45
Actual = 50

The percentage error is then calculated as:

$\% E = \frac{50 - 45}{45} \times 100\%$

Evaluate the difference

$\% E = \frac{5}{45} \times 100\%$

So, we have:

$\% E = \frac{500}{45} \%$

$\% E = 11.1\%$

Hence, the percentage error is 11.1%

The Toylot company makes an electric train with a motor that it claims will draw an average of only 0.8 ampere (A) under a norma

Igoryamba

Answer:

Step-by-step explanation:

Given that population average is 0.8 ampere

Sample size = 9

Sample mean x bar = 1.34 A

Sample std dev s = 0.48

$H_o: x bar =0.8\\H_a: x bar >0.8$

(one tailed test)

Mean difference - $1.34-0.8 =0.54$

Std error = $\frac{s}{\sqrt{n} } =0.16$

t test can be used since sigma is not known and sample size small

t statistic = mean diff/std error = 3.5

df = 8

p value = 0.00404
