Combine like terms : -1.1x + 8.1x

7x + 38 = -32

Subtract 38

7x = -70

Divide by 7

7x = -70/7

Answer:

x = -10

Answer:

1. start by subtracting 38 from both sides

-1.1x+8.1x+ (38-38)= (-38-32)

2. Solve

-1.1x+8.1x= -70

3. Add the x- values

7x=-70

Explanation:

You'll need to use a T table to answer this question. Your stats textbook should have such a table in the back appendix section.

If your textbook doesn't have the proper table, or you don't have your textbook with you, then I recommend searching online for "t table" and you should have tons of free options to choose from.

In the table you'll look for the degrees of freedom row 6, since the degrees of freedom are equal to n-1. In this case, n = 7.

In this row, locate the column labeled  "alpha = 0.005" and you'll be looking at "one tail". The value in this row and column is roughly 3.707

Since we're doing a left tailed test and we want P(t < C) = 0.005, where C is the critical value we're after. This must mean C < 0. So C = -3.707 approximately. Round this to two decimal places and we end up with -3.71

Answer:

78.383%

Step-by-step explanation:

The pH of randomly selected swimming pools follows a normal distribution with mean 7.4 and standard deviation 0.22. A pool should have a pH between 7.2 and 7.8 so that chlorine treatment is effective.

Using z score formula

z = (x-μ)/σ, where

x is the raw score

μ is the population mean

σ is the population standard deviation.

For x = 7.2

z = 7.2 - 7.4/0.22

z = -0.90909

Probability value from Z-Table:

P(x = 7.2) = 0.18165

For x = 7.8

z = 7.8 - 7.4/0.22

z = 1.81818

Probability alue from Z-Table:

P(x = 7.8) = 0.96548

The probability of pools having an acceptable pH level(7.2 and 7.8)

= P(x = 7.8) - P(x = 7.2)

= 0.96548 - 0.18165

= 0.78383

Converting to percentage

0.78383 × 100

= 78.383%

The percentage of pools having an acceptable pH level is 78.383%

The given triangle is an acute triangle and this can be determined by using the distance formula and the Pythagorean theorem.

Given :

Coordinates of triangle are --- J(-7, -7), K(-9, 1), L(-1, -1)

The following steps can be used in order to classify the given triangle:

Step 1 - First, determine the distance between the points.

[tex]\rm JK = \sqrt{(-9+7)^2+(1+7)^2} = \sqrt{4+64} = \sqrt{68}[/tex]

[tex]\rm KL = \sqrt{(-1+9)^2+(-1-1)^2} = \sqrt{64+4} = \sqrt{68}[/tex]

[tex]\rm JL = \sqrt{(-1+7)^2+(-1+7)^2} = \sqrt{36+36} = \sqrt{72}[/tex]

Step 2 - In order to classify the given triangle, the Pythagorean theorem can be used.

[tex]\rm H^2 = P^2 + B^2[/tex]

Step 3 - Substitute the values of P, H, and B in the above expression.

[tex]\rm (\sqrt{72} )^2 = (\sqrt{68} )^2 + (\sqrt{68} )^2[/tex]

Step 4 - Simplify the above expression.

72 < 136

Therefore, the given triangle is an acute triangle.

Step-by-step explanation:

Here we will use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

In this case, n = 11, r ≥ 7, p = 0.6, and q = 0.4.

P = ₁₁C₇ (0.6)⁷ (0.4)⁴ + ₁₁C₈ (0.6)⁸ (0.4)³ + ₁₁C₉ (0.6)⁹ (0.4)² + ₁₁C₁₀ (0.6)¹⁰ (0.4)¹ + ₁₁C₁₁ (0.6)¹¹ (0.4)⁰

P = 0.236 + 0.177 + 0.089 + 0.027 + 0.004

P = 0.533

Answer:1/64

Step-by-step explanation: I got it right

Based on the pattern in the table, the value of a is StartFraction 1 Over 64 EndFraction.

Exponents are the method of writing numbers, especially large numbers, in terms of a base and an exponent, which is written as the power of base.

Given is a pattern, which is the powers of 2.

The first term is 2⁻¹ = 1/2

The second term is 2⁻² = 1/ 2² = 1/4

The third term is 2⁻³ = 1 / 2³ = 1/8

The fourth term is 2⁻⁴ =  1 / 2⁴ = 1/16

The fifth term is 2⁻⁵ = 1/ 2⁵ = 1/32

The sixth term is 2⁻⁶ = 1/ 2⁶ = 1/64

So the value of a is 1/64.

Hence the value of a is 1/64.

Answer:

B

Step-by-step explanation:

Just took test on edge.

Average rate of change, miles per hour, during the interval 0.75 to 1.00 hours is 5 miles per hour.

Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.

Given a table which shows how far a distance runner has traveled since the race began.

If f(x) is a function, the average rate of change of the function in the interval [a, b] is,

f(b) - f(a) / b - a

Here the interval is (0.75, 1).

Average rate of change of the function is,

Average rate of change = (4.75 - 3.50) / (1 - 0.75)

                                        = 1.25 / 0.25

                                        = 5

Hence the required average rate of change is 5 miles per hour.
