The distance between A and B is 5.

SOVA2 [1]2 years ago
6 0

Answer:

6.4 to nearest tenth.

Step-by-step explanation:

AB = √[(x2 - x1)^2 + (y2-y1)^2]

= √[(-1 - 4)^2 + (2 - (-2))^2]

= √(25 + 16)

= 6.403

in 2001 John makes an investment investment and $50,000 decreases in value of the rate of 2.5% per year write an exponential fun
VARVARA [1.3K]

Answer:

$39811.77

Step-by-step explanation:

If we put y as the unit of year, the function will be 50000x0.975^y (100%-2.5% is 97.5%). And so from 2001 to 2010, nine years has passed, so the equation will be 50000x0.975^9 And if you calculate and round the answer to the nearest hundredth (cent), you will find $39811.77.

12What mistake did the student make when solvingtheir two-step equation?(a)b) If correctly solved what should the value of be?
mixas84 [53]

Given the equation:

\frac{x}{6}+3=-18

(a) You can identify that the student applied the Subtraction Property of Equality by subtraction 3 from both sides of the equation:

\frac{x}{6}+3-(3)=-18-(3)

However, the student made a mistake when adding the numbers on the right side.

Since you have two numbers with the same sign on the right side of the equation, you must add them, not subtract them and use the same sign in the result. Then, the steps to add them are:

- Add their Absolute values (their values without the negative sign).

- Write the sum with the negative sign.

Then:

\frac{x}{6}=-21

(b) The correct procedure is:

1. Apply the Subtraction Property of Equality by subtracting 3 from both sides (as you did in the previous part):

\begin{gathered} \frac{x}{6}+3-(3)=-18-(3) \\  \\ \frac{x}{6}=-21 \end{gathered}

2. Apply the Multiplication Property of Equality by multiplying both sides of the equation by 6:

\begin{gathered} (6)(\frac{x}{6})=(-21)(6) \\  \\ x=-126 \end{gathered}

Hence, the answers are:

(a) The student made a mistake by adding the numbers -18 and -3:

-18-3=-15\text{ (False)}

(b) The value of "x" should be:

x=-126

A software firm survey of 595 randomly selected adults showed that 38​% of them would erase all of their personal information on
algol [13]

Answer:

a. \ p=0.38\\\\b. \ \ H_o:p=0.38\\\ \ \ \ \\H_A:p\neq 0.38

Step-by-step explanation:

a. Let, p be the parameter being tested. From the sample, 38% would erase all of their personal information.

-we know that the value of probabilities are in the range [0,1]:

-Given that 38% is the true value of the claim can be symbolically expressed as p=0.5

b. The null hypothesis usually represents the true value parameter under study.

-As stated above, the true value of the parameter is 38%;

-Hence, the null hypothesis is H_o:p=0.38

#Alternative hypothesis is the control value, given the value of the parameter  p=0.38, the alternative hypothesis is that p has a different value other than 0.39:

H_A:p\neq 0.38
