Find the value of x. 7 Х 3 Z X =√[?] Pls help explain !!

Alisiya [41]

Answer:

Answer:

x = √70

Step-by-step explanation:

The triangles shown are all similar, so the corresponding sides are proportional.

hypotenuse/long side = x/7 = (7+3)/x

Cross-multiplying gives ...

x^2 = 7(10)

x = √70

_____

You will note that the value of x (the long side) is the geometric mean of the long segment and the whole hypotenuse.

A similar "geometric mean" relation holds for the short side:

BC = √(CD·CA)

There is yet another "geometric mean" relation that holds for the altitude:

BD = √(CD·AD)

Find the measure of the angle. I need to show my work, please, thank you!!!

Rina8888 [55]

Answer:

148

Step-by-step explanation

A you may have studies,

x+125+23=180

x+148=180

x=132

Angle S = 132

but to find ? you have to add U and T

so it's y=125+23=148

-n+(-4)-(-4n)+6 solve

tigry1 [53]

Answer:

3n + 2

Step-by-step explanation:

-n+(-4)-(-4n)+6

= -n -4 +4n +6 [positive plus negative = negative; ∴ +(-4) = -4

=4n - n +6 - 4 negative plus negative = positive; ∴ -(-4n) = 4]

now subtract n from 4n and subtract 4 from 6

=3n + 2

Solve 4(4f-9)=-(2-f)

Whitepunk [10]

Answer:

f = $\frac{7}{15}$

Step-by-step explanation:

1. 4(4f - 9) = -(2-f) distribute the negative

2. 4(4f - 9) = -2 + f Distribute the 4

3. 16f - 9 = -2 + f Subtract f on both sides

4. 15f - 9 = -2 Add 9 on both sides

5. 15f = 7 Divide both equations by 15

6. $\frac{15f}{15} = \frac{7}{15}$

f = $\frac{7}{15}$

(Small sample confidence intervals for a population mean) suppose you are taking a sampling of 15 measurements. you find that x=

Luda [366]

Answer:

The 99% confidence interval is $71.67 < \mu < 78.33$

Step-by-step explanation:

From the question we are told that

The sample size is $n = 15$

The sample mean is $\= x = 75$

The standard deviation is $s = 5$

Given that confidence is 99% then the level of significance is mathematically represented as

$\alpha = 100 - 99$

$\alpha = 1\%$

$\alpha = 0.01$

Next we obtain the critical values of $\frac{ \alpha }{2}$ from the normal distribution table

The value is

$Z_{\frac{ \alpha }{2} } = 2.58$

Generally the margin for error is mathematically represented as

$E = Z_{\frac{ \alpha }{2} } * \frac{ s}{ \sqrt{n} }$

=> $E = 2.58 * \frac{ 5}{ \sqrt{15} }$

=> $E = 3.3307$

The 99% confidence interval is mathematically represented as

$\= x -E < \mu < \= x +E$

=> $75 - 3.3307 < \mu$

=> $71.67 < \mu < 78.33$
