What is the value of the t score for a 99% confidence interval if we take a sample of size 22?

Elanso [62]

Answer: 2.831

Step-by-step explanation:

As per given , we have

sample size : n= 22

Degree of freedom = n-1 = 22-1=21

Significance level for 99% confidence interval = $\dfrac{1-0.99}{2}=0.005$

Using student's t-value table, we have

$t_{0.005,\ 21}=2.831$

Hence, the t score for a 99% confidence interval if we take a sample of size 22= 2.831

Does (3,4) satisfy the equation-5x + 2y = 23?

jek_recluse [69]

Answer:

$- 5x + 2y = 23 \\ when \: \: x = 3 \: and \: y = 4 \\ = - 5(3) + 2(4) \\ = - 15 + 8 \\ = 7 \\ no \: it \: doesnot \\ \\ \\ if \: equation \: is \: 5x + 2y = 23 \\ = 15 + 8 \\ = 23 \\ hence \: it \: satisfies$

Given the function f(x) = 4|x – 5| + 3, for what values of x is f(x) = 15?

KengaRu [80]

F(x) = 15 <=> 4|x-5| + 3 = 15
<=> 4|x-5| = 12
<=> |x-5| = 3
<=> x-5 = 3 (1) <=> x-5 = -3 (2)
<=> x = 8 (1) <=> x = 2 (2)
x = 8; x = 2
