The statement that must be true about square WXYZ are as follows;

WX ≅ XY
WX ≅ YZ
∠W is a right angle.

<h3>Properties of a Square.</h3>

All sides are equal to each other.
Opposite sides are parallel to each other.
All the angles are right angle.
The diagonals bisect each other and are perpendicular.

Therefore, the statement that must be true about square WXYZ are as follows;

WX ≅ XY
WX ≅ YZ
∠W is a right angle.

Ten college students were randomly selected. Their grade point averages (GPAs) when they entered the program were between 3.5 a

solong [7]

Answer:

The 95% confidence interval for the true slope is (0.03985, 0.14206).

Step-by-step explanation:

For the regression equation:

$\hat y=\alpha +\hat \beta x$

The (1 - <em>α</em>)% confidence interval for the regression coefficient or slope $(\hat \beta )$ is:

$Ci=\hat \beta \pm t_{\alpha/2, (n-2)}\times SE(\hat \beta )$

The regression equation for current GPA (Y) of students based on their GPA's when entering the program (X) is:

$\hat Y=3.584756+0.090953 X$

The summary of the regression analysis is:

Predictor Coefficient SE t-stat p-value

Constant 3.584756 0.078183 45.85075 5.66 x 10⁻¹¹

Entering GPA 0.090953 0.022162 4.103932 0.003419

The regression coefficient and standard error are:

$\hat \beta = 0.090953\\SE (\hat \beta)=0.022162$

The critical value of <em>t</em> for 95% confidence level and 8 degrees of freedom is:

$t_{\alpha/2, n-2}=t_{0.05/2, 10-2}=t_{0.025, 8}=2.306$

Compute the 95% confidence interval for $(\hat \beta )$ as follows:

$CI=\hat \beta \pm t_{\alpha/2, (n-2)}\times SE(\hat \beta )\\=0.090953\pm 2.306\times 0.022162\\=0.090953\pm 0.051105572\\=(0.039847428, 0.142058572)\\\approx (0.03985, 0.14206)$

Thus, the 95% confidence interval for the true slope is (0.03985, 0.14206).

2kg of coconut juice, which costs $5/kg, were combined with 8kg of coconut milk, which costs $3/kg. Find the cost per kg of the

katen-ka-za [31]

Cost per kg=(total cost)/(total kg)

total cost
coconut juice: 2kg, at $5/kg, so 5*2=$10
coconut milk: 8kg, at $3/kb, so 8*3=$24

total cost=10+24=$34

total kg=2+8=10

cost per kg=$34/10kg=$3.40per kg
