Analyze the reflectional symmetry of the letters.

1 answer:

Alona [7]3 years ago

5 0

Answer:

C , T , I , O , S , H , K

Step-by-step explanation:

A 1-fold reflectional symmety means that if the letter is folded in the middle (either horizontally or vertically) then both sides will be identical and match up perfectly. From the words provided the letters that have this symmetry are the following.

From "RAINY" = I

From "ACTION" = C , T , I , O

From "SHARK" = S , H , K

Each of these letters can be folded once and have both parts identical to one another.

Answer:

Option C is correct

Step-by-step explanation:

5c – 20 ≤ 15c + 10

<=> 5c - 15c ≤ 20 + 10

<=>-10c ≤ 30

<=> c ≥ -3

A random sample of 70 printers discovered that 25 of them were being used in small businesses. find the 95% limit for the popula

kvasek [131]

Answer:

The sample proportion of printers used in small business is:

$\hat{p}=\frac{25}{70}=0.3571$

The 95% confidence interval for the population proportion of printers that are used in small businesses is:

$\hat{p} \pm z_{\frac{0.05}{2}} \sqrt{\frac{\hat{p}(1-\hat{p})}{n} }$

Where:

$z_{\frac{0.05}{2}}=1.96$ is the critical value at 0.05 significance level

$\therefore 0.3571 \pm 1.96 \sqrt{\frac{0.3571(1-0.3571)}{70} }$

$0.3571 \pm 0.1122$

$\left ( 0.3571 - 0.1122, 0.3571 + 0.1122 \right)$

$\left(0.245,0.469 \right)$

Therefore, the 95% confidence interval for the population proportion of printers that are used in small businesses is (0.245 , 0.469)

HELP GEOMETRY!!!!!! The newest feature at the Great Park is the big orange balloon. The volume of this perfectly spherical ballo

WITCHER [35]

Answer: 8.3 ft

Step-by-step explanation:

Here, The volume of this perfectly spherical balloon is approximately 2361.7 cubic feet.

Since, the volume of a sphere, $V= \frac{4}{3} \pi r^3$

Where r is the radius of the sphere.

Here V= 2361.7 cubic feet

Therefore, $2361.7=\frac{4}{3} \pi r^3$

⇒ $r^3= \frac{21\times 2361.7}{88}$

⇒ $r= 563.5875^{1/3}=8.2601344693$ ≈8.3 feet

Thus, the radius of the sphere = 8.3 feet
