The point estimate would be 2.25%.

Confidence intervals are centered around a point estimate; that is, the point estimate is in the very middle of the confidence interval.  We can find the point estimate by averaging both ends of the confidence interval together:

(1.1+3.4)/2 = 2.25.

Suvita spent 25% of her pocket money on her clothes ,11% on her shoes and saved Rs. 1600 . What is her pocket money?
solong [7]

Answer:

Rs. 4,444

Step-by-step explanation:

Let her pocket money be represented as A

She spent 25% of A on her clothes and 11% on shoes and then saved Rs. 1600

Total percentage spent = 25 + 11 = 36%

So, she spent 36% of A and was left with Rs. 1600

This can be represented by the equation below

36% of A = 1600

36/100 x A = 1600

0.36 x A = 1600

Divide both sides by 0.36

0.36/0.36 A = 1600/0.36

A = 4444.44

A = Rs. 4,444

Her pocket money was approximately Rs. 4,444

In the floor tile pattern, the figure is a square and the two triangles are congruent.
Licemer1 [7]

Answer:

7.1

Step-by-step explanation:

Since it is a square you can use the Pythagorean theorem (a²+b²=c²) by filling in what you know. a²=5 and b²=5 so you have 5²+5²=c². This simplfies to 25+25=c². Now you simplify again to get 50=c². Finally you have to square root everything because the equation can't end in c², it has to be the most simplified it can be. This equals ≈7.1
