Patty says that if you add the same negative integer five times, the sign of the sum is negative and its size is five times the

size of the original integer.
For example:
(-7) + (-7) + (-7) + (-7) + (-7)
= 5 x (-7)
= - 35

Is Patty’s statement true for all integers?

Answer:

Interval is given with 97% confidence. Thus there is 3% probability that interval is not true.

Step-by-step explanation:

In Statistics, estimated intervals are given with some confidence level. In this example person develop the interval with 97% confidence.

<em>Statistically</em>, this means that the person can be 97% sure (not 100%)  that population mean is 74.3 < µ < 78.3. There is still 3% probability that population mean falls outside of the interval.

Small sample size may also lead wrong estimates.

The area of a parallelogram is 3.36 square feet. the base is 2.8 feet. if the measures of the base and height are each doubled,
kolbaska11 [484]
A =bh

Plug in values and solve for height (h).
A=3.36
b=2.8

3.36 = 2.8h
/2.8      /2.8
1.2 = h

Base and Height doubled:
b = 2.8
h = 1.2

2(2.8)=5.6
2(1.2)=2.4

Plug in new b and h to area equation given to find area:
5.6(2.4) = 13.44

Resulting parallelogram area = 13.44 ft^2

irga5000 [103]

Answer:

The tall of the flag pole is 51 ft answer (A)

Step-by-step explanation:

∵ The tall of the man = 6 ft

∵ The his shadow = 10 ft

∵ The shadow of the flag pole = 85 ft

∵ Tall of the man/tall of the flag = shadow of the man/shadow

   of the flag

∴ 6/x = 10/85 ⇒ where x is the tall of the flag

∴ x = (6 × 85) ÷ 10 = 510 ÷ 10 = 51 ft

∴ The tall of the flag pole is 51 ft
