Answer: 11

Step-by-step explanation:

We know that the degree of freedom for a t-distribution is given by :-

df=n-1, where n is the sample size.

Given : A repeated-measures experiment and a matched-subjects experiment each produce a t statistic with df = 10.

Then, the number of  individuals participated in each study = df+1=10+1=11

Hence, the number of  individuals participated in each study =11.

What are the zeros of this function? (pictured above) How do you know?
arlik [135]

Answer:

x=-1 and x=3

Step-by-step explanation:

The zeroes of a function are its x-intercepts when the function passes through the x-axis. In this case, the parabola passes through (0,-1) and (0,3) which means the x-intercepts are x=-1 and x=3, which are also the zeroes.

aliya0001 [1]

Question:

A new auditorium is being built for a college. The balcony has 200 seats. The floor has 25 rows with x seats in each row. The number of people in the auditorium must be under 750 to meet safety regulations. What is the solution of this inequality, and what is its meaning?​

Answer:

200 + 25x < 750

Number of seats in a row must be less than 22

Step-by-step explanation:

Given

Total = Less than 750

Current Seats = 200

Rows = 25

Seat per row = x

Required

Represent as an inequality

The scenario will be represented as:

Current\ Seats + Rows * x = Total

Substitute 200 for Current Seats

200 + Rows * x = Total

Substitute 25 for Rows

200 + 25* x = Total

200 + 25x = Total

Substitute <750 for Total.

The equation then becomes

200 + 25x < 750

Solving further:

25x < 750 - 200

25x < 550

x < \frac{550}{25}

x < 22

This means that:

Number of seats in a row must be less than 22
