Answer:

x = 7/6

Step-by-step explanation:

Solve for x:

35/74 (4/3 + 21/(5 x)) - 4/5 = 23/15

Bring 35/74 (4/3 + 21/(5 x)) - 4/5 together using the common denominator 1110 x:

(2205 - 188 x)/(1110 x) = 23/15

Cross multiply:

15 (2205 - 188 x) = 25530 x

Expand out terms of the left hand side:

33075 - 2820 x = 25530 x

Subtract 25530 x + 33075 from both sides:

-28350 x = -33075

Divide both sides by -28350:

Answer:  x = 7/6

QUICK WHATS THIS ANSWER?!?
Mars2501 [29]

Answer:

C. -x-6>-3.5

Step-by-step explanation:

One is asked to find which inequality has (x=-3) in its solution set. Remember that an inequality is another way to represent a set of solutions. In essence, it states that all numbers less than; less than or equal to; greater than; or greater than or equal to, are a part of the solution. One simplifies an inequality in a similar manner to how one simplifies an equation, by using inverse operations and simplification. Just note that when multiplying or dividing the inequality by a negative number, one has to flip the inequality sign to ensure the expression remains true.

Simplify each of the inequalities, then evaluate to see which one has (x=-3) as a part of its solution set.

A. -x -6

-x

x>-2.5

B. -x-6>3.5

-x>9.5

x

C. -x-6>-3.5

-x>2.5

x

D. x-6>-3.5

x>2.5

As can be seen, option (C -x-6>-3.5) is the only one that fits this requirement. Since option (C) simplifies down to (x) or in words, (x) is less than (-2.5). This option is the only one that fits the solution since (-3) is less than (-2.5).

A quality control engineer is interested in estimating the proportion of defective items coming off a production line. In a samp
fenix001 [56]

Answer:

The lower bound of a 99% C.I for the proportion of defectives = 0.422

Step-by-step explanation:

From the given information:

The point estimate = sample proportion \hat p

\hat p = \dfrac{x}{n}

\hat p = \dfrac{55}{100}

\hat p = 0.55

At Confidence interval of 99%, the level of significance = 1 - 0.99

= 0.01

Z_{\alpha/2} =Z_{0.01/2} \\ \\ = Z_{0.005} = 2.576

Then the margin of error E = Z_{\alpha/2} \times \sqrt{\dfrac{\hat p(1-\hat p)}{n}}

E = 2.576 \times \sqrt{\dfrac{0.55(1-0.55)}{100}}

E = 2.576 \times \sqrt{\dfrac{0.2475}{100}}

E = 2.576 \times0.04975

E = 0.128156

E ≅ 0.128

At 99% C.I for the population proportion p is: \hat p - E

= 0.55 - 0.128

= 0.422

Thus, the lower bound of a 99% C.I for the proportion of defectives = 0.422

A triangle has sides of lengths 12,14 and 19 . Is it a right triangle?
Scorpion4ik [409]

Answer:

It could be

Step-by-step explanation:

The calculation of sides of a rectangular triangle can be done by applying the Pythagorean theorem (the sum of the squares of the legs is equal to the square of the hypotenuse), both legs must form a right angle, and the value of the hypotenuse must be different from the legs. In the example what you give could be a value of one leg and the other of the hypotenuse.

podryga [215]

Answer:

22 minus 4 = 18

18 divided by 3 is equal to 6

then following from the question now that we got the answer

so she have 6 cards first then it tripled and now it's 18 Then she added four now it's 22

your welcome
