Answer:

0.6

Step-by-step explanation:

Given the trapezoid formula:

1/2(b1+b2/2)xH

We are given the numbers for the trapezoid:

0.3,0.9,1

To solve this here is what we are going to do.

1/2(0.9+0.3)x1

So add 0.9+0.3=1.2

Then Divide 1.2/2=0.6

So multiply 0.6 x 1=0.6

0.6 is your answer

For each situation, write an expression answering the question. The expression should only

siniylev [52]

Answer:

The expressions for each statement are as follows:

a: 2500+(0.10*2500)

b: 40 * 0.85

c: 250 + (0.075*250)

Step-by-step explanation:

Part a:

Given

Salary = $2500

Percentage of raise = 10%

The new salary will be:

$= 2500+ (10\%\ of\ 2500)\\=2500 + (0.10*2500)\\=2500+250\\=\$ 2750$

Part b:

Given

Total questions = 40

Percentage of correct answers = 85%

The required expression for correct answers is:

$= 85\%\ of\ 40\\= 0.85*40\\=34$

Part c:

Given

Price of phone = $250

Percentage of sales tax = 7.5%

The required expression is:

$Cost\ with\ sales\ tax = 250 + (7.5\%\ of\ 250) \\= 250 + (0.075*250)\\=250+18.75\\=268.75$

Hence,

The expressions for each statement are as follows:

a: 2500+(0.10*2500)

b: 40 * 0.85

c: 250 + (0.075*250)

In a certain experiment, the error made in determining the density of a substance is a random variable having a uniform density

Ganezh [65]

Answer:

The required probability is 0.1667

Step-by-step explanation:

Consider the provided information.

According to Probability Density Function: $f(x)\left\{\begin{matrix} \frac{1}{b-a}& a$

Therefore,

$f(x)\left\{\begin{matrix} \frac{1}{0.030}& -0.015$

The probability that such errors will be between –0.002 and 0.003 is:

$P(-0.002\leq x\leq 0.003)=\int\limits^{0.003}_{-0.002} {\frac{1}{0.030}} \, dx$

$P(-0.002\leq x\leq 0.003)=\frac{1}{0.030}[x]^{0.003}_{-0.002}$

$P(-0.002\leq x\leq 0.003)=\frac{0.003+0.002}{0.030}=0.1667$

Hence, the required probability is 0.1667
