In Triangle XYZ, m triangles?<br> O XYZ = TUV<br> O XYZ = VUT<br> O No congruency statement can be made because only two angles

ahrayia [7]

Answer:

No congruency statement can be made because the side lengths are unknown.

Step-by-step explanation:

We are given the measure of two angles in ∆XYZ, as 90 and 30 respectively. The 3rd angle can be known without being given. Since sum of angles in a triangle is 180°, the 3rd angle would be 180 - (90+30) = 60°.

Same applies to ∆TUV.

We only know the 3 angles of each triangle, but we are not given any of the side lengths. Therefore, we cannot make any congruency statement since the side lengths are unknown.

There is no prior information about the proportion of Americans who support the gun control in 2018. If we want to estimate 99%

Romashka-Z-Leto [24]

Answer: 13

Step-by-step explanation:

If the prior population proportion is unavailable then the formula to find the sample size is given by :-

$n=0.25(\dfrac{z^*}{E})^2$

, where z* = Critical z-value

E = margin of error

Let p be the proportion of Americans who support the gun control in 2018.

As per given , we have

Confidence level = 99%

The critical z-value for 99% confidence interval is 2.576 ( BY z-table)

Margin of error : E= 0.36

Since there no prior information about the proportion of Americans who support the gun control in 2018.

So , the required sample size to estimate 99% confidence interval would be:

$n=0.25(\dfrac{2.576}{0.36})^2=0.25(7.16)^2$

$n=0.25(51.2656)=12.8164\approx13$

Hence, 13 Americans should be surveyed.
