What is the value of y?

Mathematics
1 answer:
prohojiy [21]3 years ago
4 0

Answer:

<h2>C. 54°</h2>

Step-by-step explanation:

We know: measures of angles in a triangle add up to 180°.

Therefore we have the equation:

\gamma+\gamma+72^o=180^o      <em>subtract 72° from both sides</em>

2\gamma=108^o       <em>divide both sides by 2</em>

\gamma=54^o

4505 x 219 standard algorithm
Ymorist [56]

After throughfall calculating the multiplication 4505 x 219 in standard algorithm, we have come to find that product is 986595

<h3>What is standard algorithm?</h3>

In elementary math, a standard algorithm or method is a particular computation technique that is typically taught for resolving particular mathematical issues. In general, these techniques include exchanging, regrouping, long division, long multiplication using a standard notation, and standard formulas for average, area, and volume.

These techniques can vary somewhat by country and time, but they typically include these techniques. Similar techniques are also available for more complex functions like square roots, but they are no longer taught in general mathematics classes because calculators are more convenient.

4505 x 219 in standard algorithm is as follows:

⇒        4 5 0 5

         <u>×    2 1 9  </u>            

        4 0 5 4 5    

    +  4 5 0 5        

  +<u> 9 0 1 0         </u>

     9 8 6 5 9 5

How do u write 4 1/4 in simplest form and not in decimals I haven't learned that yet .
alexandr1967 [171]
It already is in simplest form because the numerator and denonimator don't have a common factor to then divide them by.

find the area of the figure below, composed of a rectangle and semicircle. Round it to the nearest tenth.
Alexandra [31]

Answer:

Step-by-step explanation:

radius of semicircle = 5

area of semicircle = πr² = 25π

area of rectangle = 10×14 = 140

total area = 140 + 25π ≅ 218.54 square units

mars1129 [50]

Answer:

The 80% confidence interval for difference between two means is (0.85, 1.55).

Step-by-step explanation:

The (1 - <em>α</em>) % confidence interval for difference between two means is:

CI=(\bar x_{1}-\bar x_{2})\pm t_{\alpha/2,(n_{1}+n_{2}-2)}\times SE_{\bar x_{1}-\bar x_{2}}

Given:

\bar x_{1}=M_{1}=6.1\\\bar x_{2}=M_{2}=4.9\\SE_{\bar x_{1}-\bar x_{2}}=0.25

Confidence level = 80%

t_{\alpha/2, (n_{1}+n_{2}-2)}=t_{0.20/2, (5+5-2)}=t_{0.10,8}=1.397

*Use a <em>t</em>-table for the critical value.

Compute the 80% confidence interval for difference between two means as follows:

CI=(6.1-4.9)\pm 1.397\times 0.25\\=1.2\pm 0.34925\\=(0.85075, 1.54925)\\\approx(0.85, 1.55)

Thus, the 80% confidence interval for difference between two means is (0.85, 1.55).
