Find the value of x to the nearest tenth

Bess [88]

Answer:

X = 7.24 or 7.2

Step-by-step explanation:

Tan46/1 = x/7

Cross multiply to get this outcome:

7tan(46)

Put into calculator

Then your answer will be X = 7.24 or 7.2

Hope that helps :)

If the point A (10, 4) is reflected above the line y = x. Identify the transformed point?

Nataliya [291]

The transformed point if reflected over y = x is (4, 10)

<h3>Reflection of coordinate</h3>

Reflections are transformation technique used to change the position of an image on an xy-plane.

Given the coordinate (10, 4), if this coordinate points are reflected over y =x, this shows that we will simply swap the coordinate points to have (4, 10)

Hence the transformed point if reflected over y = x is (4, 10)

2529.56068773 rouned to the nearest ten! Please help!

Nimfa-mama [501]

It would be 2529.6
Because the .5 is the 10ths place
If the number after it it 5 or greater, make it 1 number greater
If the number after is 4 or below, keep it the same
Hope this helps!

3(4g+6)=6(2y+1)<br><br><br> Does this equation have one solution, no solution, or infinite?

Inga [223]

Explanation: When finding how many solutions an equation has you need to look at the constants and coefficients. The coefficients are the numbers alongside the variables. ... If the coefficients are the same on both sides then the sides will not equal, therefore no solutions will occur.

A random sample of 16 ATM transactions at the Last National Bank of Flat Rock revealed a mean transaction time of 2.8 minutes wi

ddd [48]

The width (in minutes) of the 95 percent confidence interval for the true mean transaction time is <u>1.2786 minutes</u>.

Sample size (n) = 16.

Sample mean = 2.8 minutes.

Sample standard deviation (σ) = 1.2 minutes.

Confidence interval given = 95%.

The degree of freedom (df) can be calculated as n - 1.

df = n - 1 = 16 - 1 = 15.

Since, the level of confidence is 95%, the level of significance α = 1 - 0.95 = 0.05.

From the T-Distribution table, we take the value at critical value α/2 with the degree of freedom 15.

$t_{\frac{\alpha }{2} ,15}$ = 2.131.

Now, the margin of error can be shown as follows:

$E = t_{\frac{\alpha }{2} ,15} * \frac{\sigma}{\sqrt{n} } \\\Rightarrow E = 2.131 * \frac{1.2}{\sqrt{16} }\\ \Rightarrow E = 0.6393$

The width at the confidence interval of 95%, is twice the margin of error, that is:

Width = 2*E = 2*0.6393 = 1.2786.

Thus, the width (in minutes) of the 95 percent confidence interval for the true mean transaction time is <u>1.2786 minutes</u>.
