The ratio of red marbles to blue marbles in simplest form is 36:29

Step-by-step explanation:

Given,

Number of red marbles = 180

Number of blue marbles = 145

Ratio;

Red marbles : Blue marbles

$180:145$

As both are multiples of 5;

$\frac{180}{5}:\frac{145}{5}\\36:29$

Professor York randomly surveyed 240 students at Oxnard University and found that 150 of the students surveyed watch more than 1

BaLLatris [955]

Answer:

1727 students

Step-by-step explanation:

Here we have the formula for sample size given as

$n = \frac{p(1-p)z^2}{ME^2}$

Where:

p = Mean

ME = Margin of error = 3

z = z score

Therefore, we have

p = 150/240 = 0.625

z at 99 % = 2.575

ME = $\pm$ 3%

Therefore $n = \frac{0.625(1-0.625)2.575^2}{0.03^2} = 1726.73$

The number of students Professor York have to sample to estimate the proportion of all Oxnard University students who watch more than 10 hours of television each week within ±3 percent with 99 percent confidence = 1727 students.

May someone please help me with this :)

1. The perimeter = 3.7 + 3.7 + 2.8 + 2.8
= 13
The area = 3.7 * 2.8 = 10.36

2. Perimeter = 11.2
Area = half base times height
2.6 * 1.5 = 3.9 squared

Use the figure to find the measures of the numbered angles. ∠5 = ∠6 =

Gwar [14]

Answer:

∠ 5 = 49°, ∠ 6 = 131°

Step-by-step explanation:

∠ 5 and 49° are corresponding angles and are congruent, then

∠ 5 = 49°

∠ 5 and ∠ 6 are adjacent angles and are supplementary, sum to 180° , that is

∠ 6 + ∠ 5 = 180°

∠ 6 + 49° = 180° ( subtract 49° from both sides )

∠ 6 = 131°

Simple Interest Rate Formula: $\displaystyle A = P(1 + r)^t$

A is final amount
P is principle (initial) amount
r is rate
t is time (in years)

Step-by-step explanation:

Step 1: Define

P = 7200

r = 0.75% = 0.0075

t = 5

Step 2: Solve for A

Substitute in variables [Simple Interest Rate Formula]: $\displaystyle A = 7200(1 + 0.0075)^5$
(Parenthesis) Add: $\displaystyle A = 7200(1.0075)^5$
Evaluate exponents: $\displaystyle A = 7200(1.03807)$
Multiply: $\displaystyle A = 7474.08$
