The product od 2 and y is at least 10

Hey can you please help me

Answer:

C

Step-by-step explanation:

General Form of an equation of a line is given by: $y=mx+b$

Where,

m is the slope, and

b is the y-intercept (point where line cuts the y-axis)

Also, parallel lines have equal slopes.

Equation of first plane is given as $d=3.67t+4.81$

Comparing this with general form of a line, we see that 3.67 is the slope and 4.81 is the y-intercept.

The second plane is going parallel to this. So slope should be same. Hence second plane has slope of 3.67. We can write:

$d=3.67t+c$

To find the equation of second plane, we need to solve for c. Also, a point given for second plane is $(t=0, d=2.14)$ , substituting these values into the equation we got, we get the value of c:

$2.14=3.67(0)+c\\2.14=0+c\\c=2.14$

We already know m and now we know c, so we can write final equation as:

$d=3.67t+2.14$

Answer choice C is right.

Which equation has no solution

Olegator [25]

Answer:

The first option has no solution.

Step-by-step explanation:

The absolute value of any number, whether it be positive or negative, results as positive.

With the equation listed, you CAN NOT obtain a negative number as your result, therefore this equation has NO SOLUTION.

The pH of a solution is measured eight times by one operator using the same instrument. She obtains the following data: 7.15, 7.

Nikolay [14]

Answer:

(a)7.185

(b)0.000371

(c) 0.019

(d)Sample variance and Sample standard deviation

Step-by-step explanation:

We are given the following sample data.

7.15, 7.20, 7.18, 7.19, 7.21, 7.20, 7.17, 7.18.

(a) Calculate the sample mean. Round your answer to 3 decimal places.

The formula for sample mean =

Sum of terms/Number of terms

= 7.15 + 7.20+ 7.18+7.19+7.21+7.20+7.17+ 7.18/8

= 57.48/8

= 7.185

(b) Calculate the sample variance. Round your answer to 6 decimal places.

The formula for sample Variance =

(x - mean)²/n - 1

n = 8

Sample variance = (7.15 - 7.185)² + (7.20-

7.185)²+ (7.18 -7.185)² + (7.19 -7.185)² + (7.21 - 7.185)² + (7.20 - 7.185)² + (7.17 - 7.185)² + (7.18 - 7.185)² /8 - 1

= 0.001225 + 0.000225+ 0.000025+ 0.000025 + 0.000625 + 0.000225 + 0.000225 + 0.000025/7

= 0.0026/7

= 0.000371428571

Approximately to 6 decimal places = 0.000371

(c) Calculate the sample standard deviation. Round your answer to 3 decimal places.

The formula for Sample Standard Deviation = √Sample variance

= √0.000371428571

= 0.01927248223

To 3 decimal places = 0.019

(d) Which of the following are potential major sources of variability in the experiment
