Answer:

2

Step-by-step explanation:

Fill in the x and y with the values you are trying to find.

-7(2^2 -6)+2(-6)

distribute the -7 and 2 into the parenthesis after squaring the 2.

(-28+42)-12

simplify

A complex number is a number that can be written in the form a + bi, where a and b are real numbers. In the complex number 4 + 2
IRISSAK [1]

Answer:

In the complex number 4 + 2i, 4 is the <em>real </em>part. In the complex number 4 + 2i, 2 is the <em>imaginary </em>part.

Step-by-step explanation:

The two parts of the complex number are called the <em>real</em> part and the <em>imaginary</em> part. The imaginary part is identified by its multiplier of <em>i</em>.

In the given number, the 2 is multiplied by i, so 2 is the imaginary part. The other part, 4, is the real part.

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC b
iragen [17]

The student made the mistake in Step 2.

It should be m∠o + m∠p = 180 (Supplementary angles)

If this is corrected, then, since m∠m + m∠n + m∠o = 180 from Step 1,

we have,

m∠m + m∠n + m∠o = m∠o + m∠p which is Step 3.

Cancelling m∠o both sides, we get,

m∠m + m∠n = m∠p which is Step 4.

A study was conducted to determine whether magnets were effective in treating pain. The values represent measurements of pain us
amm1812

Answer:

Given:

Sham: n= 20,     x=0.44,   s=1.24,

Magnet:n= 20,  x =0.49,   s= 0.95

For Sham:

Sample size, n = 20

Sample mean = 0.44

Standard deviation = 1.24

For Magnet:

Sample size = 20

Sample mean = 0.49

Standard deviation = 0.95

The null and alternative hypotheses:

H0: s1²=s2²

H1: s1² ≠ s2²

a) To find the test statistics, use the formula:

\frac{s1^2}{s2^2}

\frac{1.24^2}{0.95^2} = \frac{1.5376}{0.9025} = 1.7037

Test statistics = 1.7037

b) P-value:

Sham: degrees of freedom = n - 1 = 20 - 1 = 19

Magnet: degrees of freedom = n - 1 = 20 - 1 = 19

The critical values:

[Za/2, df1, df2)], [(1 - Za/2), df1, df2]

f[0.05/2, 19, 19], f[(1 - 0.05/2), 19, 19]

f[0.025, 19, 19], f[0.975, 19, 19]

(2.526, 0.3958)

The rejection region:

Reject H0, if  F < 0.3958 or if F > 2.526

c) Conclusion:

Since the critical values of test statistic is between (0.3958 < 1.7037 < 2.526), we fail to reject null hypothesis H0.

There is insufficient evidence to to support the claim that those given a sham treatment have reductions that vary more than those treated with magnets

Jaquan practices soccer every three days. He practices basketball every five days Jaquan practiced both today. How many days unt
Svetach [21]

Answer: He will practice both on every 15 days.

Step-by-step explanation:

Given: Jaquan practices soccer every 3 days.

He practices basketball every 5 days Jaquan practiced both today.

The number of days until he practices both = Least common multiple of 3 and 5

= 3 x 5    [Both are primes]

= 15

Hence, he will practice both on every 15 days.

  • Least common multiple  of two numbers p and  q is the smallest number that is divisible by both p and q.
