Answer:
Dante can make two different quadrilaterals with four sides equal
Step-by-step explanation:
we know that
A <u><em>rhombus</em></u> is a four-sided shape where all sides have equal length.
Also opposite sides are parallel and opposite angles are equal
A <u><em>square</em></u> has equal sides and every angle is a right angle (90°)
Also opposite sides are parallel.
therefore
Dante can make two different quadrilaterals with four sides equal
A Square and a Rhombus
Answer:
The correct answer is D
Step-by-step explanation:
The range of the function is all real numbers greater than or equal to 0.
X/6 + 4 = 15
First, subtract 4 to both sides:
x/6 = 11
Now multiply 6 to both sides:
x = 66
Answer:
90% confidence interval for the population mean is between a lower limit of $92.18 and an upper limit of $107.82.
Step-by-step explanation:
Confidence interval for a population mean is given as mean +/- margin of error (E)
mean = $100
sd = $25.20
n = 30
degree of freedom = n-1 = 30-1 = 29
confidence level (C) = 90% = 0.9
significance level = 1 - C = 1 - 0.9 = 0.1 = 10%
critical value (t) corresponding to 29 degrees of freedom and 10% significance level is 1.699
E = t×sd/√n = 1.699×25.20/√30 = $7.82
Lower limit of population mean = mean - E = 100 - 7.82 = $92.18
Upper limit of population mean = mean + E = 100 + 7.82 = $107.82
90% confidence interval is ($92.18, $107.82)
The name of place value of 9 in 199 is ones.
The second 9 has a value of tens.
The number 1 has a place value of hundreds.
