Answer:

  ∠4 = 45°

Step-by-step explanation:

Angles 1, 2, and 4 are all congruent.

  ∠4 = ∠2

  x +30 = 2x +15

  15 = x . . . . . . . . . . . . . subtract x+15

  x + 30 = 45 = ∠4

sergey [27]

Answer:

  4. 11/6, 121/36

  5. 5/8, 25/64

  6. 4/7, 16/49

  7. 14/9, 196/81

Step-by-step explanation:

The ratio of perimeters is the same as the ratio of corresponding legs:

  perimeter ratio = red leg/blue leg

The area ratio is the square of that:

  area ratio = (perimeter ratio)²

__

<h3>4.</h3>

perimeter ratio = 11/6

area ratio = (11/6)² = 121/36

__

<h3>5.</h3>

perimeter ratio = 5/8

area ratio = (5/8)² = 25/64

__

<h3>6.</h3>

perimeter ratio = 4/7

area ratio = (4/7)² = 16/49

__

<h3>7.</h3>

perimeter ratio = 14/9

area ratio = (14/9)² = 196/81

1. A researcher is interested in whether drinking different sources of caffeine (tea vs. coffee) leads
g100num [7]

The researcher's scientific/alternative hypothesis is:

  • Different sources of caffeine leads to differences in women's attentional control performance.

The researcher's null hypothesis is:

  • Different sources of caffeine leads to no difference in women's attentional control performance.

The type of sample which the researcher is using is:

  • Probability sampling.

A disadvantage to using this sample type is:

  • It is time consuming.

The thing which the researcher can conclude about these data is:

  • It is conclusive based on the reaction of the women to the independent variables.

If, in the population, women actually show NO difference in attentional control performance after drinking black tea versus coffee, the type of statistical error which the researcher has made is:

  • Type I error

<h3>What is a Scientific Hypothesis?</h3>

This refers to the difference between two variables which is discovered during a scientific research and is an observed pattern.
