Please Answer!!!!

Morgarella [4.7K]

Answer:

A). F = $\frac{9C}{5}+32$

B). 374°F

Step-by-step explanation:

A). Formula to convert the temperature from degree centigrade to °F is,

C = $\frac{5}{9}(F-32)$

We have to solve the formula to get the value of F,

9 × C = $9\times \frac{5}{9}(F-32)$

9C = 5(F - 32)

$\frac{9C}{5}=\frac{5(F-32)}{5}$

$\frac{9C}{5}=(F-32)$

F = $\frac{9C}{5}+32$

B). In this part we have to find the value of 190° C in °F.

From the formula given in part (A),

F = $\frac{9\times 190}{5}+32$

= 374°

Therefore, 190°C = 374°F

Suppose that the probability a seed will germinate is 85%. What is the probability that 7 of these seeds will germinate when 10

Viktor [21]

Total number of outcomes of 7 from 10 = 10*9*8 / 3*2*1 = 120
probability of each outcoe is 0.85^7* (0.15)^(3) = 0.0010819

Required probability = 120 * 0.0010819 = 0.1298

Triangle SUT is an isosceles triangle and you can prove this by a geometric proof.
We can set SU = ST.
2x + 11 = 11x - 16

Solve for x:
9x = 27
x = 3
