Answer:

Option B.

Step-by-step explanation:

In a circuit shown in the figure two diodes are attached in which arrow shows the direction of current allowed by the diodes.

When key S1 is closed current flows from electric source to S1 then bulb. Afterwards if key S3 is closed current will pass through S3 and diode. Therefore to light the bulb circuit will be a closed circuit if S1 and S3 both are closed.

Therefore option B. is the correct answer.

The answer is b because from s1 it goes to s3 and then it can go through the center of s2 and s3 and resume its curcuit

Assume the competing hypotheses take the following form: H0: µ1 – µ2 = 0, HA: µ1 – µ2 ≠ 0, where µ1 is the population mean for p
DedPeter [7]

Answer:

t=\frac{\bar x_1- \bar x_2}{\sqrt{\frac{s_1^2}{n_1} +\frac{s_2^2}{n_2} } }

Step-by-step explanation:

H0: µ1 – µ2 = 0

HA: µ1 – µ2 ≠ 0

We have given,

The population variances are not known and cannot be assumed equal.

The test statistic for the test is

t=\frac{\bar x_1- \bar x_2}{\sqrt{\frac{s_1^2}{n_1} +\frac{s_2^2}{n_2} } }

Where,

\bar x_1 = sample meaan of population 1

\bar x_2 = sample mean of population 2

n_1 = sample size of population 1

n_2 = sample size of population 2

Therefore, this is the test

t=\frac{\bar x_1- \bar x_2}{\sqrt{\frac{s_1^2}{n_1} +\frac{s_2^2}{n_2} } }

What expression is equivalent to 486-9+6+3^*2
sattari [20]

Answer:

The expression equivalent to 486-9+6+3^*2 is 500-7+6+5^*2

Step-by-step explanation:

486-9+6+3^*2 = 500-7+6+5^*2

486-9+6+9 = 500-7+6+25

486-24 = 500-38
