Answer:
x≥4
Step-by-step explanation
24+4x≥40. Subtract 24 from both sides to get 4x≥16. Divide both sides by 4 to get x≥4.
For this case, the first thing we must do is define a variable.
We have then:
x: unknown number
We now write the expression that models the problem:
From here, we clear the value of x.
We have then:
Answer:
4/9 divided by 1/27 equals 12
To evaluate this function, we use the calculator. We change the setting to radian first because we are using pi and thensimply input the cosine of 7 pi over 8. Then we square the answer. <span>We expect this number to be less than 1. </span>The function value is 0.8536.
Answer:
HL
Step-by-step explanation:
Since both triangles are right angle triangles that means one angle is 90°. other two sides are given congruent .
that means lengths of hypotenuse and the leg of the one right angle triangle is equal to the corresponding other hypotenuse and leg of other triangle.
This fulfills the condition of HL congruency.
Answer:
Step-by-step explanation:
The margin of error is computed using the formula:
The critical of <em>z</em> for 95% confidence level and 90% confidence level are:
*Use a <em>z</em>-table.
The sample size is n = 44.
Compare the MOE for 95% confidence level and 90% confidence level as follows:
