Solution:

we are given that

RSTV is an isosceles trapezoid with bases RV and ST and MN || RV.

As we can see from the given diagram the value of angle

Since the trapezoid is isosceles so the base angle will be equal.

Hence we can write

Since

Which expression fits this description?

otez555 [7]

Numerator:
the product of 5 and the sum of x and y = 5(x + y)

Denominator:
the product of negative 8 and x = -8x

So the quotient:

5(x + y)
------------
- 8x

Answer is the second one.

5(x + y)
------------
- 8x

A professor thinks that the students in her statistics class this term are less creative than most students at this university.

choli [55]

Answer:

It is not enough evidence to reject null hypothesis. It is not enough evidence to say that mean score is not equal to 35.

Step-by-step explanation:

$\mu=35\\n=23\\\=x=33\\s=5\\\alpha=0.1$

1. Null and alternative hypothesis

$H_{0}:\mu=35\\H_{1}:\mu$

2. Significance level

$\alpha=0.1\\1-\alpha=0.99$

Freedom degrees is given by:

$v=n-1\\v=23-1=22$

For a sgnificance level of 0,01 and 22 freedom degrees, t-student distribution value is:

$t_{0.01;23}=-2. 5083$

3. Test statistic

$t=\frac{\=x-\mu}{\frac{s}{\sqrt{n} } }$

$t=\frac{33-35}{\frac{5}{\sqrt{23} } }$

$t=-1,918$

In this case, we have an one left tailed analysis, it means that null hypothesis is rejected if $t$

$-1.918>-2.5083$

Conclusion:

It is not enough evidence to reject null hypothesis. It is not enough evidence to say that mean score is not equal to 35.

Here is a list of four fractions 1/16 2/8 15/60 3/9

aleksley [76]

Answer:

3/9

Step-by-step explanation:

15*4= 60 so 15/60 is equivalent to 1/4.

1/16 is just a smaller equivalent of 2/8 which is just a smaller equivaent of 1/4.

3/9 simplified is 1/3. I/s is bigger than 1/4.

Hope this helps

The point (4,-2) is the vertex of the graph of a quadratic function. The points (8,6) and (2,0) also fall on the graph of the fu

Elina [12.6K]

Answer:

Step-by-step explanation:

y = ax² + bx + c

~~~~~~~

(4, - 2), (8, 6), (2, 0)

a(4²) + b(4) + c = - 2

a(8²) + b(8) + c = 6

a(2²) + b(2) + c = 0

16a + 4b + c = - 2 .............. (1)

64a + 8b + c = 6 ............... (2)

4a + 2b + c = 0 ................. (3)

a = 0.5 ; b = - 4 ; c = 6

y = 0.5x² - 4x + 6

Part A: (0, 6), (6, 0)

Part B: (0,6)

Part C: (6, 0)

Part D: [ 4, ∞ )
