According to the National Center for Health​ Statistics, in​ 1990, 28 % of babies in the United States were born to parents who

were not married. Throughout the​ 1990s, this increased by approximately 0.6% per year. If this trend​ continues, in which year will 79% of babies be born out of​ wedlock?

Subtract 79% by 28% to find out how much % you would have to rise. We get 51. We will divide that by 0.6 because we want to know how many 0.6's are in 51 years.

The result is 85, so 1990 + 85 is 2075.

For a random sample of Harvard University psychology majors, the responses on political ideology had a mean of 3.18 and standard
Nutka1998 [239]

Answer:

From the test give in the question it is obvious that  there is enough evidence to show that population mean varies for vegetarian and non-vegetarian

The P-value helps affirm the null hypothesis claims,The P-value attains  values relatively as large as that which exists in the sample given,if the null hypothesis is right

Step-by-step explanation:

From the question we are told that

Sample mean \=x_1=3.18

Standard deviation \delta_! =1.72

Sample size n_1 =51

Sample mean \=x_2=2.22

Standard deviation \delta_2 =0.67

Sample size n_2=20

Generally this is a two tailed test

therefore

   Null hypothesis  = h_0 :P_v_e_g= P_n_o_n_v_e_g

  Alternative hypothesis H_a : P_v_e_g \neq  P_n_o_n_v_e_g

From the test give in the question it is obvious that  there is enough evidence to show that population mean varies for vegetarian and non-vegetarian

The P-value helps affirm the null hypothesis claims,The P-value attains  values relatively as large as that which exists in the sample given,if the null hypothesis is right

I need help with this question :|
True [87]

Answer:

see explanation

Step-by-step explanation:

Note the ratios between consecutive terms is constant, that is

- 220 ÷ 11 = 4400 ÷ - 220 = - 88000 ÷ 4400 = - 20

Thus to obtain the next term in the sequence multiply the previous term by - 20

Start with 11 and multiply by - 20

The temperature in degrees Celsius, c, can be converted to degrees Fahrenheit, f, using the equation f-c+32. Which
Basile [38]

It is a function because every Celsius temperature is associated with only one Fahrenheit temperature. Therefore, option B is true.

<h3>How to convert Celsius into Fahrenheit ?</h3>

We are given that the temperature in degrees Celsius C can be converted to degrees Fahrenheit F

We know that the formula

\dfrac{C}{5} = \dfrac{F - 32}{9}

If we are substituting c = -40

Then, we get

\dfrac{C}{5} = \dfrac{F - 32}{9}\\\\\dfrac{-40}{5} = \dfrac{F - 32}{9}\\\\-8 \times 9 = F - 32\\\\F = -72 + 32\\\\F = -40

For every Celsius temperature, we get only one value of Fahrenheit.

The function is one-one because for every value of Celsius we get a unique value of Fahrenheit.

Hence, it is a function because every Celsius temperature is associated with only one Fahrenheit temperature.

Therefore, option B is true.
