Yellow or blue is 5/7 of the spinner

Multiply 70 by 5/7 to find the prediction of the number of times it will land there

70(5/7) = 50

If a triangle with vertices A(-1, 4), B(-1, -2), C(2, -2) is dilated with a scale factor of 2 and a center of dilation at the or

givi [52]

Answer:

A' (-2,8) B' (-2,-4) C' (4,-4)

Step-by-step explanation:

Dilations Rule :

(x,y) → (kx,ky)

Scale factor = K

When your scale factor is more than one our triangle gets bigger. When your scale factor is less than one our triangle gets smaller.

( you plug in 2 in every point and those are your answers).

Remember negative times negative is positive and positive times negative is negative.

In an effort to make childrenâs toys safer and more tamperproof, toy packaging has become cumbersome for parents to remove in ma

Monica [59]

Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Old design samples(n1) = 220

New design samples (n2) = 220

P1 = 81/220 = 0.368 ; P2 = 41/220 = 0.186

Null hypothesis : p1 - p2 ≥ 0.05

Alternative hypothesis : p1 - p2 < 0.05

Using the test statistic formula :

t = (P1 - P2) / √[P(1-P)(1/n1 + 1/n2)]

P = (81 + 41)/(220 + 220) = 122/440 = 0.277

1 - P = 0.723

t = (0.368 - 0.186) / (√(0.277(0.723)(1/220 + 1/220)))

t = 4.265

P value from z test at α = 0.05

P value = 0.00002

Test for significance at α = 0.01 ;

Test for significance at α = 0.1

Result is significant at both α levels, hence reject the Null.

0.325 is _____ 100 percent. less than greater than equal to

Liono4ka [1.6K]

Answer:

Option A is correct.

0.325 is less than 100 percent.

Step-by-step explanation:

Given: 0.325 is ____100 percent

Convert decimal into percent..

It is done by multiplying the decimal value by 100.

0.325 becomes

$0.325 \times 100 = \frac{325}{1000} \times 100 = 32.5\%$

32.5 % < 100 %

⇒ 32.5 % is less than 100 %

Therefore, 0.325 is less than 100 percent.
